14 * Christophe Boyanique -- added an optional egrep alias for grep.
15 * Christophe Boyanique -- added optional 'rm -i' support.
16 * Kenneth Chalmers and Erik Andersen -- fixed ln so it

121 * Larry Doolittle -- shell data structure cleanup, fixed buglets
122 in read, exec, and piped builtins
123 * Erik Andersen -- md5sum was broken in 0.48. Now fixed (and doesn't

125 * ?? -- squashed memory leak in shell prompt handling
126 * Mark Whitley -- Updates to style guide
127 * Mark Whitley -- Big cleanup in utility.c: style guide compliance,

132 * Erik Andersen -- updates so you can now select from the Makefile
133 whether or not to use the system's passwd and group functions.
134 Since most systems use GNU libc, this can save you from having to
135 install the /etc/nsswitch.conf configuration file and the required
136 libnss_* libraries. Adds 1.5k. You can now, also, disable this,
137 causing busybox to use the system's pwd.h and grp.h functions.
140 -Erik Andersen, 27 January 2001
144 * Glenn McGrath -- tar now supports uncompressing tar files,
145 define BB_FEATURE_TAR_GZIP to use the -z option.
146 * Matt Kraai -- fix all usage of TRUE and FALSE so all apps now
147 return EXIT_SUCCESS or EXIT_FAILURE to the system.
148 Now TRUE and FALSE are set to the C standard where TRUE=1.
149 * me -- Fixed uname problem causing the kernel version to be
150 mis-detected (causing problems with poweroff, init,
152 * Alcove, Julien Gaulmin <julien.gaulmin@alcove.fr> and
153 Nicolas Ferre <nicolas.ferre@alcove.fr> -- insmod support on ARM
154 and StrongArm, and suport for lsmod on older 2.0.x kernels.
155 * Kent Robotti -- Renamed unrpm to original rpmunpack, so you can use
156 an included shell script called unrpm as a front end to it. There's
157 also a shell script called undeb included for debian packages.
158 * Matt Kraai -- fix an infinite loop with ls -aR
159 * Larry Doolittle -- Shaved off about 100 bytes and 200 bytes heap
160 from date.c. Also document the "-d" option in the usage message.
161 * Gennady Feldman -- fixed dd to use blocksize when reading/writing,
162 (it was reading the whole thing and then writing it out). Also
163 updated usage information (was missing conv=notrunc) and added
165 * Larry Doolittle (in collaboration with Matt Kraai) -- allow for a
166 pristine source directory -- where all the .o files and such are
167 not placed into the source tree. Thanks Larry!
168 * Larry Doolittle -- use the applet definitions in applets.h
169 to autogenerate the applet function and usage prototypes.
170 * Sebastien Huet, Arne Bernin, and Kent Robotti -- Add in tar -X and
171 fixed a bug breaking tar --exclude.
172 * Jonas Holmberg -- echo option handling made GNU-echo compatible
173 * Aleksey Demidov <asd@ixcelerator.com> -- date option handling made
175 * me -- Progress meter (optional) in wget
176 * Doolittle/me -- programs invoked by full path name take
177 precedence over applets unless BB_FEATURE_SH_BUILTINS_ALWAYS_WIN
178 * Gaute B Strokkenes <gs234@cam.ac.uk> -- applets found using a
179 binary search instead of linear search. Much faster!
180 * new applets: cmp readlink
181 * Mark Whitley -- Removed advertising clause of Berkeley license
182 according to decision by the Regents of the University of
183 California; included reference
184 * tail's confusing special treatment of single digit options removed;
185 people should use -n instead
186 * Larry Doolittle -- \r handled now in echo and tr
187 * Matt Kraai -- rewrite of uniq
188 * Mark Whitley -- remix of xargs
189 * Jim Gleason <jimg@lineo.com> -- fixed tar so it no longer breaks
191 * Matt Kraai -- logger now logs all arguments, not just the first
192 * Gennady Feldman -- syslogd no longer logs to localhost if compiled
193 for remote logging...
194 * Richard June <rjune@ims1.imagestream-is.com> -- support for 'gzip -d'
195 * various artists -- Other good stuff that I forgot to document.
198 -Erik Andersen, 13 December 2000
202 * A bug in syslogd was fixed that allowed it to potentially fork-bomb
203 your system. Anyone using 0.46 syslogd should upgrade.
204 * Renamed busybox.defs.h to the more sensible "Config.h"
205 * Improved portability between different libcs.
206 * Many apps ported to use getopt()
207 * Common handling of '--help'
208 * All usage messages centralized.
209 * Added a bunch of new commands:
210 * 'rdate' contributed by Sterling Huxley <sterling@europa.com>
211 * 'wget' contributed by Chip Rosenthal <chip@unicom.com>,
212 <crosenth@covad.com> and Covad Communications
213 * 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
214 * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
215 debugging) thanks to Kent Robotti <robotti@metconnect.com>.
216 * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
217 * 'xargs' (written by me)
218 * 'expr' contributed by Edward Betts <edward@debian.org>, based
220 * lsmod now uses the query_module syscall, rather then /proc (me)
221 * syslogd can now log messages to remote hosts -- patch thanks
222 to Gyepi Sam <gyepi@praxis-sw.com>
223 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
224 * 'make install' now creates relative symlinks, and added a new
225 'make install-hardlinks' target to (tada) install hardlinks.
226 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
227 It now weighs only 2.25k (3k when full featured). The code is
228 cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
229 * Add optional ls file sorting, thanks to a patch from
230 Sterling Huxley <sterling@europa.com>
231 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'
232 now work (previously it thought -r was an option). Doh!
233 * Fixed tar handling of stdin and stdout
234 * Renamed "internal.h" to the more sensible "busybox.h"
235 * Preliminary support for GNU HURD.
236 * Updated my devps and devmtab kernel patches for the latest 2.2.x
237 kernel, for those wanting to go proc-less.
238 * Tons of other bugfixes.
241 -Erik Andersen, 25 September 2000
246 * Better portability. Now should compile cleanly with libc5,
247 GNU libc 2.0 and 2.1, and various Linux kernels including
248 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
249 to make /proc/mounts behave included in the kernel-patches dir).
250 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
251 local files that matched tarball contents!!! Fix thanks
252 to Marius Groeger <mgroeger@sysgo.de>
253 * Fixed a nasty bug in tar when could mess up saved symlinks.
254 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
255 thanks to Daniel Quinlan <quinlan@transmeta.com>
256 * Updates to handle Linux 2.4.0 kernels (kludged around the
257 "none" entries in /proc/mounts, added a hack to make sysinfo
258 work with both old and new kernels).
259 * Fixed insmod module option parsing for options lacking an '='.
260 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
261 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
262 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
263 * Several fixes from Marius Groeger <mag@sysgo.de>
264 - Added support for "sh -c command args..."
265 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
266 - Added shell environment variable substitution
267 - Added the "read" shell builtin.
268 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
269 used to create an infinite loop: ls, cursor up, left, down.
270 * Added support for being a login shell, so things like
271 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
272 invoke the shell. Now you can use BusyBox as a login shell.
273 * ls.c now ignores '-g', since some ftp clients like that sort
274 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
275 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
276 it always sets the controlling terminal before running any programs
277 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
278 - Fixed tr so it recognizes standard escape sequences.
279 Merged common escape seq. code from tr and echo into utility.c.
280 - Major work in updating/cleaning up the docs, and getting the
281 new SGML based docs into shape.
283 - BusyBox should now poweroff when asked to do so.
284 - Fixed 'ln -n' and 'ln -s' so they both work properly.
285 * Reorganized signal names in kill.c for better architecture support
286 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
287 * In 0.43, backspace and delete worked properly, but with 0.45,
288 it just echoed a ^? for backspace, and ^H for control-h. This
289 was due to a broken macro in init.c, that is now fixed.
290 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
291 couldn't maintain it very well, so including it was not really
292 very appropriate. Those wanting an fdisk are invited to
293 grab a copy from util-linux.
294 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
295 then be loaded in by 'loadkmap' -- submitted by
296 Arne Bernin <arne@matrix.loopback.org>
297 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
298 * Brand, new versions of grep and sed which use libc regex routines,
299 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
300 "regexp.[ch]" files have been removed. Much help on these from
304 -Erik Andersen, 11 July 2000
308 * Now compiles vs libc5 (which can save lots of space for
310 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
311 help messages (i.e --help). Saves 17k over a full compile.
312 * Added cut and tr from minix, since due to the license change,
313 we can now use minix code. Minix tr saves 4k.
314 * insmod now works. It costs 29k, but imagine an initrd with a
315 staticly linked busybox containing only insmod and sh, a few /dev
316 entries, and a kernel module or two... It doesn't get smaller
317 then this folks (I pity the fool that writes insmod in asm ;-).
318 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
319 * Added a mini ar archive utility, especially written for BusyBox by
320 Glenn McGrath <bug1@netconnect.com.au>
321 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
322 * Added setkeycodes, for those that have wierd keyboard buttons.
323 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
324 <ams@trillian.itslinux.org> for contributing these.
325 * Added 'grep -v' option (inverted search) and updated
326 docs accordingly. -beppu
328 * Replaced the telnet implementation with one written by
329 Tomi Ollila <too@iki.fi> It works great and costs 3k.
330 * BusyBox sh (lash) now supports being used as a standalone shell. When
331 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
332 be invoked as shell internals. Best used when compiling staticly
334 * BusyBox sh (lash) internals now behave as expected wrt pipes
336 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
337 * Fixed update segfault
338 * Fixed mknod -- minor number was always 0
339 * Fixed tar option parsing, so both "tar xvf foo.tar" and
340 "tar -xvf foo.tar" now work (i.e. no "-" before options)
341 (this was very broken in 0.43).
342 * Several contributions from Randolph Chung <tausq@debian.org>.
343 * cp/mv now accepts the -f flag
344 * tail can now accept -<num> commands (e.g. -10) for better
345 compatibility with the standard tail command
346 * added a simple id implementation; doesn't support sup. groups yet
347 * logname used getlogin(3) which uses utmp. Now it doesn't.
348 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
349 * Add support for "noatime" and "nodiratime" mount flags to mount.
350 * Changed 'umount -f' to mean force, and actually use umount2.
351 * Changed 'umount -l' to mean "Do not free loop device".
352 * Fixed basename to support stripping of suffixes. Patch thanks
353 to xiong jianxin <jxiong@uiuc.edu>
354 * cp -fa now works as expected for symlinks (it didn't before)
355 * zcat now works (wasn't working since option parsing was broken)
356 * Renamed "mnc" to the more correct "nc" (for netcat).
357 * Makefile intelligence updates
358 * Changed the way init parses /etc/inittab entries to avoid problems
359 with commands that contain colons in them. Fix thanks to
360 Pavel Roskin <proski@gnu.org>
361 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
362 Fix thanks to Pavel Roskin <proski@gnu.org>
363 * Made "killall" complain (not error and exit) about processes that it
364 cannot find by name -- Pavel Roskin <proski@gnu.org>
365 * Fixed more and ps to have sensible terminal width defaults, thanks
367 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
368 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
369 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
370 * Fixed segfault caused by "touch -c"
371 * Fixed segfault caused by "rm -f"
372 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
373 and "--" support from Pavel Roskin.
374 * Fixed segfault caused by "cp -a -a" and similar abuses.
375 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
376 * "which" rewritten to use stat(). Fixes to improve its compatability
377 with traditional implementations -- Pavel Roskin.
378 * "mount" now reports errors from nfsmount() and assumes NFS mount
379 if ':' is present in the device name - Pavel Roskin
380 * Fixed exit status for killall - Pavel Roskin
381 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
382 * Fixed 'mount -a' so it works as expected.
383 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
384 * Implemented "ping -s", fixed error messages and argument parsing -
386 * Syslogd will not go to background if "-n" is given. Better help
387 and argument checking -- Pavel Roskin
388 * Fixed a small bug that could cause tar to emit warning messages
389 and not extract the first file in a directory in some cases
390 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
391 for helping track this one down.
393 * Fixed grep "Line too long" problem -- John Beppu
394 * Fixed 'grep -q -i B some_file' so it works
395 * math takes input from stdin if no args are given. -- John Beppu
396 * math was renamed to dc. Although it deviates from dc's behaviour,
397 this will probably be remedied in the future. -- John Beppu
400 -Erik Andersen, June 21, 2000
404 Previously, an erronous announcement of BusyBox 0.44 was made, so to
405 avoid possible confusion, we are skipping straight to 0.45, and calling
412 * Major update to the provided documentation.
413 * Busybox now includes a shell! It currently costs 7.5 k (plus an
414 additional 2.5 k if you compile in command line editing). Handles
415 job control, has the usual set of builtins, and does everything
416 except for handling programming statements (if, while, etc...)
417 * Busybox can now work perfectly when /proc is disabled, thereby
418 saving a bunch of memory (kernel /proc support is not thin). This
419 is done by making use of some nice kernel patches I wrote up to
420 support the features that busybox requires and that /proc usually
421 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
422 patch your kernel with the devps patch in the kernel-patches/
424 * Wrote basename, dirname, killall, and uptime.
425 * tar has been completely rewritten by me. Both tar creation and
426 extraction are now well behaved. Costs 7.6k with all optional
427 tar features enabled, and 5k for just tar extraction support.
428 * Added freeramdisk, which will free up all memory associated
429 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
430 and then adjusted a bit by me.
431 * Added tr from John Lombardo <john@deltanet.com>
432 * Added echo and test (from me).
433 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
434 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
435 * Several fixes from Pavel Roskin <proski@gnu.org>:
436 - When `tail' fails to open a file it now exits.
437 - When `syslogd' is given the `-n' option it should still use
438 fork() for running klogd.
439 * nslookup types are now changed to u_int32_t (instead of uint32_t)
440 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
441 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
442 to count hard-linked files more then once). Many thanks to
443 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
444 * Removed /proc dependancies for init and free (while maintaining
445 exactly the same functionality). /proc takes up 90k of kernel
446 space, so it is nice to avoid using it at all costs.
447 * init no longer tries to mount /proc (unless there is less the 1 meg
448 free). Use of /proc (or not) is policy that should be set up in
449 /etc/fstab (or in hardcoded scripts), not in init.
450 * Fixed rebooting when init runs as an initrd.
451 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
452 - update.c rewritten to look more like update-2.11
453 - moveed the inode hash out of du.c and into utility.c to make
454 it a common resource that can be used by other apps.
455 - cp_mv.c now checks inodes to see if a source and dest are
456 the same, and prints an error (instead of endlessly looping).
457 - mv now attempts to do a rename, and will fall back to doing
458 a copy only if the rename fails.
459 - Syslogd now supports multiple concurrent connections
460 * Several fixes from Pavel Roskin <proski@gnu.org>:
461 - Fixes to sort. Removed "-g", fixed and added "-r"
462 - Fixes to the makefile for handling "strip"
463 * An initial telnet implementation was added by
464 Randolph Chung <tausq@debian.org>.
465 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
466 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
467 to match the terminal (defaults to width=79 when this is off).
468 * ps now accepts (and ignores) all options except for "--help" (which
469 as would be expected displays help).
470 * Fixed mount'ing loop devices when the filesystem type was not
471 specified. It used to revert to non-loop after the first try.
472 * all mallocs now use xmalloc (and so are OOM error safe), and
473 the common error handling saves a few bytes. Thanks to
474 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
475 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
476 * Fix symlink following bug in chmod -R and friends.
477 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
478 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
487 * Fairly massive restructuring of umount.c to deal with remounting
488 busy devices read-only. Adds a -r option to control that; it is
489 optionally compiled in with BB_FEATURE_REMOUNT
490 * Added a bunch of functions to mtab.c to interact with the
491 {get,set,end}mntent interface; as it turns out, those functions do
492 not appear to be re-entrant, and that causes a lot of problems with
493 the way umount was originally written.
494 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
495 to be more consistent with sysvinit
496 * Changes to init.c to use the new -r option to umount. Also increased
497 the sleep time between the time the TERM and KILL signals are sent
502 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
503 extensively rewritten from the original cp.c.
504 * Fixed cp and mv so if the source and destination are a the
505 same directory it will print an error and continue.
506 * Also added a warning message to the `mv' usage string saying that
507 this is not GNU mv, and it will break hard links. cp also breaks
509 * ln.c: implemented `-n' switch, no-deref symlinks.
510 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
511 * name buffer overrun guards to prevent future crashes.
512 - Always check exit status.
513 - Purge all use of `creat()', replace with `open()'.
515 - recursiveAction was overriding the value of followLinks thus
517 - isDirectory now takes a followLinks boolean, updated all callers
518 - copyFile had the followLinks logic reversed.
519 * messages.c: New file. Put common error message strings all in
520 one place in an attempt to shrink the binary a little.
525 * changed fsck_minix.c to reduce its .bss size significantly
527 * Made tar creation support in busybox tar optional. You no longer
528 * _have_ to put a "-" in front of tar options. Tar could inadvertently
529 * change permissions and ownership on
530 certain directories pointed to by symlinks.
531 * Made grep and grep -h do the right thing wrt printing
532 the file name (it failed to print files names in many cases).
533 * Fix a namespace aliasing problem wereby if du was built in, the
534 symlink for both du and dutmp would be installed, or then rm was
535 built in, the symlinks for both rm and rmmod would be installed.
536 * Added a closelog() to init.c after loging -- fix thanks to
537 Taketoshi Sano <kgh12351@nifty.ne.jp>
538 * Rewrote and simplified logger. Added the "-t" option, and made it
539 behave itself a bit better.
540 * Optional support contributed by Ben Collins <bcollins@debian.org>
541 for the kernel init chroot patch by Werner Almesberger, which
542 allows init to chroot to a new device, and umount the old one.
543 * Fixed bug that wouldn't let one chown a symlink -- it would
544 always dereference before. -beppu
545 * Fixed a bug where init could have reference already freed memory.
546 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
547 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
548 * Added (and documented) "-n" option for head
549 * Cleanup for a number of usage messages -- also
550 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
551 * Cosmetic fix to busybox.c (Don't print a comma at the
552 end of line if there are no more application names).
553 * Fixed a stupid bug in "head" option handling ("head -n"
555 * Moved commonly used functions "xmalloc()" and "exit()"
556 to utility.c (with proper #ifdef's).
557 * Created a tiny tail implementation, removing -c, -q, -v, and making
558 tail -f work only with a single file. This reduced tail from 6k to
559 2.4k. The bigger/more featured tail can still be had by disabling
560 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
561 * Ping now falls back to doing the right thing if /etc/protocols
563 * Fixed mount and umount. Previously they could leak loop device
564 allocations, causing the system to quickly run out. Fix for umount
565 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
566 * ls formatting on eight charactor user names fixed by
567 Randolph Chung <tausq@debian.org>.
568 * cp could, when copying symlinks, change permissions of the
569 files pointed to by the symlinks.
570 * Several fixes from Pavel Roskin <proski@gnu.org>:
571 - `chown' with 1 argument displayed the error incorrectly
572 - `fdflush', `length' and `printf' crashed if run without arguments
573 - `fdflush' tried to flush itself using *argv
574 - added "skip" and "seek" to dd.
575 - ls no longer messus up output when combining files and
576 directories on the command line
577 * swapoff -a was not working. Now it is.
578 * init did not cleanly unmount filesystems on reboot. Now it does.
579 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
581 * Some architectures (PowerPc) assume chars are unsigned, so they could
582 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
583 * Began converting error handling to use some common routines
585 * syslogd now has better message handling and ignores SIGHUP.
586 * install.sh had a bug preventing installation to the specified
587 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
588 * You can now spefify alternative strip commands -- change
589 also from Gilbert Coville.
595 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
596 by Edward Betts <edward@debian.org>
597 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
598 type commands (file in a directory to another directory) from
600 * Fixed a logger bug that caused garbage to be written to the syslog
601 (unless you used busybox syslog, which hid the bug). Thanks to
602 Alex Holden <alex@linuxhacker.org> for the fix.
603 * /bin/true and /bin/false were echoing a blank line when run.
605 * mkdir -p would print an error when asked to mkdir an existing dir
606 with no interveining subdirectories.
607 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
608 * and support in umount for loop
609 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
610 <bcollins@debian.org>
611 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
612 * fullWrite() not only if BB_TAR is defined, but also
613 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
614 * add some compiler optimizations to further reduce executable size
615 (as a side note, on my machines the largest code is generated
616 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
618 * Compile now won't fail if busybox.def.h defines
619 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
620 referenced, but not compiled)
621 * Fixed a bug in setting TERM for serial console support. TERM now
622 defaults to "ansi" for serial consoles.
623 * Fixed a bug in handling the CONSOLE env. variable for serial
626 -Erik Andersen, Jan 15, 2000
629 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
630 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
631 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
632 for loading application character maps for Unicode fonts.
633 * Major init re-work. init now supports inittab (slightly different
634 but similar to sysvinit), allowing me to get all the policy out of
635 init and into the conf file. It works just fine without inittab
636 being present, but if you dont like the default behavior you can
637 now do something about it. Init is much cleaner as a result.
638 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
639 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
640 * failure of 'logger -p'. -erik Added the -s option to du -beppu
641 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
642 with the 2.0.x Linux kernel.
643 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
645 * Grep -i previously failed on UPPER CASE patterns due to a silly
646 regexp implementation bug that is now fixed.
647 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
648 * Fixed a bug where tar would not set the user and group on device
650 * Fixed a bug where tar would not restore the time to files. Fixed a
651 * major security problem with tar -- it changed ownership
652 of any file pointed to by a symlink to 777 (like say libc....)
654 * cp and mv were very broken when moving directories. I have rewritten
655 them so they should now work as expected.
656 * sed now supports addresses (numeric or regexp, with negation) and
657 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
658 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
659 * Some cosmetic fixes to ls output formatting to make it behave more
661 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
662 * <fwv@myrtle.lahn.de>:
663 - Added gunzip -t, removed gunzip.c dead code,
664 - fixed several typos
665 - Glibc 2.0.7 and libc5 compile fixes
666 * Fixed a bug where 'mknod --help' would segfault.
669 -Erik Andersen, Jan 07, 2000
672 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
673 <tausq@debian.org>. 3 items off the TODO list!
674 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
675 * tail from GNU textutils-1.19, but adjusted
676 to suit my evil purposes. Costs 6k. I'll make it smaller
678 * on reboot, init called 'umount -a -n', which caused errors
679 when BB_MTAB was not enabled. Changed to 'umount -a', which does
681 * init will now try to run /sbin/getty if it is present (for easy
682 integration with the about-to-be-released tinylogin.)
683 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
684 * -l' was failing on long directories, since my_getid was leaking
685 one file descriptor per file. Oops.
686 * Fixed rebooting from init. I'd accidently left some debugging code
688 which blocked reboots.
689 * Fixed reboot, halt (and added poweroff) such that they handle it when
690 init is not at PID 1 (like when running in an initrd).
691 * Added a prelinary du implementation. Some parameter parsing
692 stuff still needs to be added. -beppu (John Beppu
694 * Implemented tee. -beppu Implemented head. -beppu
696 -Erik Andersen, Dec 10, 1999
699 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
701 * df will not exit on error, but will stat all mounted filesystems.
702 * Fixed tar so uid/gid/permissions on extracted tarballs will be
704 * Fixed find -name so it properly uses shell wildcard patterns
705 (i.e. `*', `?', and `[]') instead of regular expressions, which
706 was causing some confusing and unexpected behavior.
707 * Added klogd to syslogd, so now the log will contain both system and
709 * syslogd now creates the /dev/log socket to make sure it is there, and
710 is actually a socket with the right permissions.
711 * I've taken a first step to making busybox not need the /proc
712 filesystem. Most apps don't need it. Those that _require_ it,
713 will complain if you enable them when you disable
714 BB_FEATURE_USE_PROCFS.
716 -Erik Andersen, Dec 5, 1999
719 * Wrote a micro syslogd, and a logger util (to log things to the syslog
720 from the command line or scripts) With both compiled in, costs 4k.
721 * Fixed 'make install' so symlinks are installed in their proper
722 * locations. Changed the build system slightly so that features can
724 or disabled from the busybox.defs.h header file, without trying to
725 compile in a source file named after that featue (unless that file
727 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
728 * -r' both work. dd now properly handles input beyond 1 block from
729 * stdin. Fixed a bug where tar unpacked everything a directories.
731 from createPath into mkdir where it belonged, thereby making tar
733 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
735 last file in the list.
736 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
738 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
739 are presented properly.
743 -Erik Andersen, Nov 25, 1999
746 * fixed dd so it properly defaults to stdin and stdout when no
747 if= and of= are set (fix thanks to Eric Delaunay).
748 * Don't try to close the file descriptor of a pipein tar. (fix also
751 * Made createPath be quiet (again thanks to Eric Delaunay). If
752 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
753 command you define it as will be run if the init script exits.
754 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
755 * NFS support added to mount by Eric Delaunay. It costs 10k when
757 in, but that is still a big win for those that use NFS.
758 * Made 'rm -f' be silent for non-existant files (thanks to Eric
759 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
761 and acts as god intended gunzip and zcat to act. They answer
762 --help and obey the '-c' flag.
763 * Fixed a bug in mv which caused it to not move files when the
766 * Fixed a decimal-instead-of-octal bug causing mkdir to make
768 with very wrong permissions.
769 * chmod would overwrite file permissions instead of modifying them.
770 Now it properly modifies permissions.
771 * Init now sends warnings destined for the console to /dev/console to
773 they show up on whatever the active console it. Otherwise
774 important messages (for example that the system is rebooting) were
775 not seen when switched to a different VT.
777 -Erik Andersen, Nov 17, 1999
780 * gzip now obeys the principle of least surprise and acts like god
782 (i.e. it accepts a file name, answers --help, and obeys the '-c'
783 flag and only then outputs to stdout).
784 * Fixed more.c to compile autowidth on sparc and set initial winsize
785 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
787 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
788 * tar now accepts --help chmod, chown, and chgrp usage now works
789 * General usage (i.e. --help) cleanups for most apps umount now parses
790 * options correctly tar can now unpack tarballs containing device
792 sockets, and fifos (though it can't pack them up) thanks to Matt
793 Porter. Creating archives containing these is still left to the
795 * fixed up the license in more.c to properly point to Bruce Perens.
797 -Erik Andersen, Nov 11, 1999
800 * ls -l now displays link names outside the current directory,
801 Patch thanks to Eric Delaunay
802 * init now properly handles sparc serial consoles and does a
803 better job of finding the real console device rather than using
804 /dev/console which doesn't support job control. Patch also thanks
806 * more started to read from stdin after the last file was finished, and
807 options were not parsed correctly (fix thanks to Eric Delaunay).
808 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
809 * rm wouldn't remove a symlink unless the symlink was valid. This was
810 a side effect of the busybox 0.32 recursiveAction() fix. Things
811 should now work correctly.
812 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
813 * it does. sed was appending a \n to the end of lines with
815 Now it doesn't do that.
816 * ls -l now bypasses libc6 nss when displaying user/group names.
817 Now uses my_getpwuid and my_getgrgid.
819 -Erik Andersen, Nov 8, 1999
822 * Fixed a bug where init could hang instead of rebooting.
823 * Removed some debugging noise from init.c
824 * Fixed ln so it works now (it was very broken).
825 * Fixed df so it won't segfault when there is no /etc/fstab,
826 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
827 is not installed (since they cannot fixup "/dev/root" to
828 state the real root device name)
829 * merged some redundant code from mtab.c/df.c into utility.c
831 -Erik Andersen, Nov 5, 1999
834 * More changes -- many thanks to Lineo for paying me to work on
835 busybox. If you have any problems please let me know ASAP at
836 andersen@lineo.com or andersee@debian.org
837 * usage() now prints the BusyBox version. This will help folks
838 realize that they are not in Kansas anymore.
839 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
840 * arguments. Now it doesn't do that. kill wasn't properly accepting
841 * signal names. It does now. Added new apps chvt and deallocvt (I
842 * should probably add open) Major rewrite of init.c. Code is now
843 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
844 * with full regular expressions!). Fixed a stupid seg-fault in sync
845 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
846 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
847 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
848 * cost of ~1.5k and the need for a rw /etc)
849 folks to use a real /etc/mtab file instead of a symlink to
850 /proc/mounts. mount, and umount will add/remove entries and df
851 will now use /etc/mtab if BB_MTAB is defined.
852 * Fixed a nice bug in recursiveAction() which caused it to infinitely
853 hunt through /proc/../fd/* creating new file descriptors if it
854 followed the /dev/fd link over to /proc. recursiveAction() now
855 lstat's the file when followLinks==FALSE so it won't follow links
856 as the name suggests. Fix thanks to Matt Porter
860 -Erik Andersen, Nov 4, 1999
863 * I added a changelog for version 0.30. adjusted find internals to
864 * make it smaller, and removed
866 * Fixed a segfault in ps when /etc/passwd or /etc/group
867 are absent. Now will warn you and carry on.
868 * Added in optional _real_ regular expression support (to be
869 the basis for a future sed utility). When compiled in it adds
870 3.9k, but makes grep much more capable.
871 * Checked out using nftw(3) for recursive stuff, but unfortunatly
872 it wasn't supported before GNU libc 2.1, and some folks use glibc
873 2.0.7 since it is much smaller than that latest and greatest.
875 -Erik Andersen, Oct 21, 1999
878 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
879 paying me to make these updates. If you have any problems with busybox,
880 or notice any bugs -- please let me know so I can fix it. These
884 * busybox can now invoke apps in two ways: via symlinks to the
885 busybox binary, and as 'busybox [function] [arguments]...'
886 * When invoked as busybox, the list of currently compiled in
887 functions is printed out (no this is not bloat -- the list has
888 to be there anyway to map invocation name to function).
889 * busybox no longer parses command lines for apps or displays their
890 usage info. Each app gets to handle (or not handle) this for
892 * Eliminated monadic, dyadic, descend, block_device, and
893 postprocess. It was cumbersome to have so many programs
894 cobbled together in this way. Without them, the app is much
896 * All shared code now lives in utility.c, and is properly
897 ifdef'ed to be only included for those apps requiring it.
898 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
899 so now each app has the function prototype of (da-dum): extern
900 int foo_main(int argc, char** argv); which speeds integration
902 * Adjusted the Makefile to make it easier to
903 {en|dis}able debugging.
904 * Changed default compiler optimization to -Os
905 (optimize for smaller binaries).
908 * To cope with the new app function prototype and the removal of
909 monadic, dyadic, etc, the following apps were re-written:
910 * cat - Works same as always. chgrp, chmod, chown -
911 * rewrite. Combined into a single
912 source file. Absorbed patches from Enrique Zanardi
913 <ezanard@debian.org> that removes the dependency on
914 libc6 libnss* libraries.
915 * cp - Can now do 'cp -a' can can copy devices,
916 pipes, symlinks, as well as recursive or non-recursive
918 * fdflush - adjusted to remove dependancy on struct
919 * FileInfo. find - Now includes some basic regexp matching
920 which will be the basic of a future mini-sed.
921 * ln - Same functionality. mkdir - Added -p flag to
922 * feature set. mv - rewrite. rm - Added -f flag to
923 * feature set. rmdir - Same functionality. swapon,
924 * swapoff - Combined into a single binary. No longer
925 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
927 * touch - Same functionality. date - adjusted with a patch
928 * from Matthew Grant <grantma@anathoth.gen.nz>
929 to accomodate glibc timezone support. I then ripped out GNU
931 * mkswap -- new version merged from util-linux. Can now make
933 * Replaced the old and star, unstar, and tarcat with the tar
934 implementation from sash. Now tar behaves as god intended it
935 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
936 * dd -- rewritten. Can with with files, stdin, stdout. Added the
937 * following new apps: loadfont -- added from debian boot floppies
938 * chroot -- added based on a patch from Paolo Molaro
939 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
940 * simple strings ps -- I just wrote it. Has _no_ options at all,
941 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
943 internationalization and such to make them smaller.
944 * sfdisk -- Added from util-linux (minus
945 * internationalization and such). Probably some other
946 * changes that I forgot to document...
948 -Erik Andersen, Oct 20, 1999
951 This version was a messy pre-alpha. stay away or it will bite you.
952 -Erik Andersen, Sep 24, 1999
955 mini-netcat (mnc) rewritten.
958 Mount now supports -a, and -t auto.
959 Mount now updates mtab correctly for 'ro'.
960 More checks screen rows size, outputs bytes percentage.
961 Printf added as module.
963 Touch now creates files. -c option for no create.
