140 given just one arg (tries to make a link in the cwd).
141 * Magnus Damm -- added a tftp applet
142 * Magnus Damm -- powerpc support for busybox insmod.
143 * David Douthitt -- fixed a build error in df.c when

257 install the /etc/nsswitch.conf configuration file and the required
258 libnss_* libraries. Adds 1.5k. You can now, also, disable this,
259 causing busybox to use the system's pwd.h and grp.h functions.
262 -Erik Andersen, 27 January 2001
266 * Glenn McGrath -- tar now supports uncompressing tar files,
267 define BB_FEATURE_TAR_GZIP to use the -z option.
268 * Matt Kraai -- fix all usage of TRUE and FALSE so all apps now
269 return EXIT_SUCCESS or EXIT_FAILURE to the system.

271 * me -- Fixed uname problem causing the kernel version to be
272 mis-detected (causing problems with poweroff, init,
274 * Alcove, Julien Gaulmin <julien.gaulmin@alcove.fr> and
275 Nicolas Ferre <nicolas.ferre@alcove.fr> -- insmod support on ARM
276 and StrongArm, and suport for lsmod on older 2.0.x kernels.
277 * Kent Robotti -- Renamed unrpm to original rpmunpack, so you can use
278 an included shell script called unrpm as a front end to it. There's
279 also a shell script called undeb included for debian packages.
280 * Matt Kraai -- fix an infinite loop with ls -aR
281 * Larry Doolittle -- Shaved off about 100 bytes and 200 bytes heap
282 from date.c. Also document the "-d" option in the usage message.
283 * Gennady Feldman -- fixed dd to use blocksize when reading/writing,
284 (it was reading the whole thing and then writing it out). Also
285 updated usage information (was missing conv=notrunc) and added
287 * Larry Doolittle (in collaboration with Matt Kraai) -- allow for a
288 pristine source directory -- where all the .o files and such are
289 not placed into the source tree. Thanks Larry!
290 * Larry Doolittle -- use the applet definitions in applets.h
291 to autogenerate the applet function and usage prototypes.
292 * Sebastien Huet, Arne Bernin, and Kent Robotti -- Add in tar -X and
293 fixed a bug breaking tar --exclude.

299 precedence over applets unless BB_FEATURE_SH_BUILTINS_ALWAYS_WIN
300 * Gaute B Strokkenes <gs234@cam.ac.uk> -- applets found using a
301 binary search instead of linear search. Much faster!
302 * new applets: cmp readlink
303 * Mark Whitley -- Removed advertising clause of Berkeley license
304 according to decision by the Regents of the University of
305 California; included reference
306 * tail's confusing special treatment of single digit options removed;

308 * Larry Doolittle -- \r handled now in echo and tr
309 * Matt Kraai -- rewrite of uniq
310 * Mark Whitley -- remix of xargs
311 * Jim Gleason <jimg@lineo.com> -- fixed tar so it no longer breaks
313 * Matt Kraai -- logger now logs all arguments, not just the first
314 * Gennady Feldman -- syslogd no longer logs to localhost if compiled
315 for remote logging...
316 * Richard June <rjune@ims1.imagestream-is.com> -- support for 'gzip -d'
317 * various artists -- Other good stuff that I forgot to document.
320 -Erik Andersen, 13 December 2000
324 * A bug in syslogd was fixed that allowed it to potentially fork-bomb
325 your system. Anyone using 0.46 syslogd should upgrade.
326 * Renamed busybox.defs.h to the more sensible "Config.h"
327 * Improved portability between different libcs.
328 * Many apps ported to use getopt()

335 * 'getopt' from "Alfred M. Szmidt" <ams@trillian.itslinux.org>
336 * dos2unix, unix2dos, reset, and unrpm.c (and lots of help
337 debugging) thanks to Kent Robotti <robotti@metconnect.com>.
338 * 'renice' command, thanks to Dave Cinege <dcinege@psychosis.com>
339 * 'xargs' (written by me)
340 * 'expr' contributed by Edward Betts <edward@debian.org>, based
342 * lsmod now uses the query_module syscall, rather then /proc (me)
343 * syslogd can now log messages to remote hosts -- patch thanks
344 to Gyepi Sam <gyepi@praxis-sw.com>
345 * chroot can now call the builtin shell - Pavel Roskin <proski@gnu.org>
346 * 'make install' now creates relative symlinks, and added a new
347 'make install-hardlinks' target to (tada) install hardlinks.
348 * Rewrite of 'tail' to make it simpler, smaller, and more robust.
349 It now weighs only 2.25k (3k when full featured). The code is
350 cleaner too, thanks to Allen Soard <esp-software@mail.hypermart.net>
351 * Add optional ls file sorting, thanks to a patch from
352 Sterling Huxley <sterling@europa.com>
353 * Fixed chmod option parsing so things like 'chmod -r /tmp/file'

355 * Fixed tar handling of stdin and stdout
356 * Renamed "internal.h" to the more sensible "busybox.h"
357 * Preliminary support for GNU HURD.
358 * Updated my devps and devmtab kernel patches for the latest 2.2.x
359 kernel, for those wanting to go proc-less.
360 * Tons of other bugfixes.
363 -Erik Andersen, 25 September 2000
368 * Better portability. Now should compile cleanly with libc5,
369 GNU libc 2.0 and 2.1, and various Linux kernels including
370 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
371 to make /proc/mounts behave included in the kernel-patches dir).
372 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
373 local files that matched tarball contents!!! Fix thanks
374 to Marius Groeger <mgroeger@sysgo.de>
375 * Fixed a nasty bug in tar when could mess up saved symlinks.
376 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
377 thanks to Daniel Quinlan <quinlan@transmeta.com>
378 * Updates to handle Linux 2.4.0 kernels (kludged around the
379 "none" entries in /proc/mounts, added a hack to make sysinfo
380 work with both old and new kernels).
381 * Fixed insmod module option parsing for options lacking an '='.
382 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
383 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
384 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
385 * Several fixes from Marius Groeger <mag@sysgo.de>
386 - Added support for "sh -c command args..."
387 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
388 - Added shell environment variable substitution
389 - Added the "read" shell builtin.
390 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
391 used to create an infinite loop: ls, cursor up, left, down.
392 * Added support for being a login shell, so things like
393 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
394 invoke the shell. Now you can use BusyBox as a login shell.
395 * ls.c now ignores '-g', since some ftp clients like that sort
396 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
397 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
398 it always sets the controlling terminal before running any programs
399 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
400 - Fixed tr so it recognizes standard escape sequences.
401 Merged common escape seq. code from tr and echo into utility.c.
402 - Major work in updating/cleaning up the docs, and getting the
403 new SGML based docs into shape.
405 - BusyBox should now poweroff when asked to do so.
406 - Fixed 'ln -n' and 'ln -s' so they both work properly.
407 * Reorganized signal names in kill.c for better architecture support
408 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
409 * In 0.43, backspace and delete worked properly, but with 0.45,
410 it just echoed a ^? for backspace, and ^H for control-h. This
411 was due to a broken macro in init.c, that is now fixed.
412 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
413 couldn't maintain it very well, so including it was not really
414 very appropriate. Those wanting an fdisk are invited to
415 grab a copy from util-linux.
416 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
417 then be loaded in by 'loadkmap' -- submitted by
418 Arne Bernin <arne@matrix.loopback.org>
419 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
420 * Brand, new versions of grep and sed which use libc regex routines,
421 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
422 "regexp.[ch]" files have been removed. Much help on these from
426 -Erik Andersen, 11 July 2000
430 * Now compiles vs libc5 (which can save lots of space for
432 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
433 help messages (i.e --help). Saves 17k over a full compile.
434 * Added cut and tr from minix, since due to the license change,
435 we can now use minix code. Minix tr saves 4k.
436 * insmod now works. It costs 29k, but imagine an initrd with a
437 staticly linked busybox containing only insmod and sh, a few /dev
438 entries, and a kernel module or two... It doesn't get smaller
439 then this folks (I pity the fool that writes insmod in asm ;-).
440 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
441 * Added a mini ar archive utility, especially written for BusyBox by
442 Glenn McGrath <bug1@netconnect.com.au>
443 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
444 * Added setkeycodes, for those that have wierd keyboard buttons.
445 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
446 <ams@trillian.itslinux.org> for contributing these.
447 * Added 'grep -v' option (inverted search) and updated
448 docs accordingly. -beppu
450 * Replaced the telnet implementation with one written by
451 Tomi Ollila <too@iki.fi> It works great and costs 3k.
452 * BusyBox sh (lash) now supports being used as a standalone shell. When
453 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
454 be invoked as shell internals. Best used when compiling staticly
456 * BusyBox sh (lash) internals now behave as expected wrt pipes
458 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
459 * Fixed update segfault
460 * Fixed mknod -- minor number was always 0
461 * Fixed tar option parsing, so both "tar xvf foo.tar" and
462 "tar -xvf foo.tar" now work (i.e. no "-" before options)
463 (this was very broken in 0.43).
464 * Several contributions from Randolph Chung <tausq@debian.org>.
465 * cp/mv now accepts the -f flag
466 * tail can now accept -<num> commands (e.g. -10) for better
467 compatibility with the standard tail command
468 * added a simple id implementation; doesn't support sup. groups yet
469 * logname used getlogin(3) which uses utmp. Now it doesn't.
470 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
471 * Add support for "noatime" and "nodiratime" mount flags to mount.
472 * Changed 'umount -f' to mean force, and actually use umount2.
473 * Changed 'umount -l' to mean "Do not free loop device".
474 * Fixed basename to support stripping of suffixes. Patch thanks
475 to xiong jianxin <jxiong@uiuc.edu>
476 * cp -fa now works as expected for symlinks (it didn't before)
477 * zcat now works (wasn't working since option parsing was broken)
478 * Renamed "mnc" to the more correct "nc" (for netcat).
479 * Makefile intelligence updates
480 * Changed the way init parses /etc/inittab entries to avoid problems
481 with commands that contain colons in them. Fix thanks to
482 Pavel Roskin <proski@gnu.org>
483 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
484 Fix thanks to Pavel Roskin <proski@gnu.org>
485 * Made "killall" complain (not error and exit) about processes that it
486 cannot find by name -- Pavel Roskin <proski@gnu.org>
487 * Fixed more and ps to have sensible terminal width defaults, thanks
489 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
490 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
491 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
492 * Fixed segfault caused by "touch -c"
493 * Fixed segfault caused by "rm -f"
494 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
495 and "--" support from Pavel Roskin.
496 * Fixed segfault caused by "cp -a -a" and similar abuses.
497 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
498 * "which" rewritten to use stat(). Fixes to improve its compatability
499 with traditional implementations -- Pavel Roskin.
500 * "mount" now reports errors from nfsmount() and assumes NFS mount
501 if ':' is present in the device name - Pavel Roskin
502 * Fixed exit status for killall - Pavel Roskin
503 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
504 * Fixed 'mount -a' so it works as expected.
505 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
506 * Implemented "ping -s", fixed error messages and argument parsing -
508 * Syslogd will not go to background if "-n" is given. Better help
509 and argument checking -- Pavel Roskin
510 * Fixed a small bug that could cause tar to emit warning messages
511 and not extract the first file in a directory in some cases
512 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
513 for helping track this one down.
515 * Fixed grep "Line too long" problem -- John Beppu
516 * Fixed 'grep -q -i B some_file' so it works
517 * math takes input from stdin if no args are given. -- John Beppu
518 * math was renamed to dc. Although it deviates from dc's behaviour,
519 this will probably be remedied in the future. -- John Beppu
522 -Erik Andersen, June 21, 2000
526 Previously, an erronous announcement of BusyBox 0.44 was made, so to
527 avoid possible confusion, we are skipping straight to 0.45, and calling
534 * Major update to the provided documentation.
535 * Busybox now includes a shell! It currently costs 7.5 k (plus an
536 additional 2.5 k if you compile in command line editing). Handles
537 job control, has the usual set of builtins, and does everything
538 except for handling programming statements (if, while, etc...)
539 * Busybox can now work perfectly when /proc is disabled, thereby
540 saving a bunch of memory (kernel /proc support is not thin). This
541 is done by making use of some nice kernel patches I wrote up to
542 support the features that busybox requires and that /proc usually
543 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
544 patch your kernel with the devps patch in the kernel-patches/
546 * Wrote basename, dirname, killall, and uptime.
547 * tar has been completely rewritten by me. Both tar creation and
548 extraction are now well behaved. Costs 7.6k with all optional
549 tar features enabled, and 5k for just tar extraction support.
550 * Added freeramdisk, which will free up all memory associated
551 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
552 and then adjusted a bit by me.
553 * Added tr from John Lombardo <john@deltanet.com>
554 * Added echo and test (from me).
555 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
556 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
557 * Several fixes from Pavel Roskin <proski@gnu.org>:
558 - When `tail' fails to open a file it now exits.
559 - When `syslogd' is given the `-n' option it should still use
560 fork() for running klogd.
561 * nslookup types are now changed to u_int32_t (instead of uint32_t)
562 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
563 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
564 to count hard-linked files more then once). Many thanks to
565 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
566 * Removed /proc dependancies for init and free (while maintaining
567 exactly the same functionality). /proc takes up 90k of kernel
568 space, so it is nice to avoid using it at all costs.
569 * init no longer tries to mount /proc (unless there is less the 1 meg
570 free). Use of /proc (or not) is policy that should be set up in
571 /etc/fstab (or in hardcoded scripts), not in init.
572 * Fixed rebooting when init runs as an initrd.
573 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
574 - update.c rewritten to look more like update-2.11
575 - moveed the inode hash out of du.c and into utility.c to make
576 it a common resource that can be used by other apps.
577 - cp_mv.c now checks inodes to see if a source and dest are
578 the same, and prints an error (instead of endlessly looping).
579 - mv now attempts to do a rename, and will fall back to doing
580 a copy only if the rename fails.
581 - Syslogd now supports multiple concurrent connections
582 * Several fixes from Pavel Roskin <proski@gnu.org>:
583 - Fixes to sort. Removed "-g", fixed and added "-r"
584 - Fixes to the makefile for handling "strip"
585 * An initial telnet implementation was added by
586 Randolph Chung <tausq@debian.org>.
587 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
588 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
589 to match the terminal (defaults to width=79 when this is off).
590 * ps now accepts (and ignores) all options except for "--help" (which
591 as would be expected displays help).
592 * Fixed mount'ing loop devices when the filesystem type was not
593 specified. It used to revert to non-loop after the first try.
594 * all mallocs now use xmalloc (and so are OOM error safe), and
595 the common error handling saves a few bytes. Thanks to
596 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
597 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
598 * Fix symlink following bug in chmod -R and friends.
599 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
600 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
609 * Fairly massive restructuring of umount.c to deal with remounting
610 busy devices read-only. Adds a -r option to control that; it is
611 optionally compiled in with BB_FEATURE_REMOUNT
612 * Added a bunch of functions to mtab.c to interact with the
613 {get,set,end}mntent interface; as it turns out, those functions do
614 not appear to be re-entrant, and that causes a lot of problems with
615 the way umount was originally written.
616 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
617 to be more consistent with sysvinit
618 * Changes to init.c to use the new -r option to umount. Also increased
619 the sleep time between the time the TERM and KILL signals are sent
624 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
625 extensively rewritten from the original cp.c.
626 * Fixed cp and mv so if the source and destination are a the
627 same directory it will print an error and continue.
628 * Also added a warning message to the `mv' usage string saying that
629 this is not GNU mv, and it will break hard links. cp also breaks
631 * ln.c: implemented `-n' switch, no-deref symlinks.
632 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
633 * name buffer overrun guards to prevent future crashes.
634 - Always check exit status.
635 - Purge all use of `creat()', replace with `open()'.
637 - recursiveAction was overriding the value of followLinks thus
639 - isDirectory now takes a followLinks boolean, updated all callers
640 - copyFile had the followLinks logic reversed.
641 * messages.c: New file. Put common error message strings all in
642 one place in an attempt to shrink the binary a little.
647 * changed fsck_minix.c to reduce its .bss size significantly
649 * Made tar creation support in busybox tar optional. You no longer
650 * _have_ to put a "-" in front of tar options. Tar could inadvertently
651 * change permissions and ownership on
652 certain directories pointed to by symlinks.
653 * Made grep and grep -h do the right thing wrt printing
654 the file name (it failed to print files names in many cases).
655 * Fix a namespace aliasing problem wereby if du was built in, the
656 symlink for both du and dutmp would be installed, or then rm was
657 built in, the symlinks for both rm and rmmod would be installed.
658 * Added a closelog() to init.c after loging -- fix thanks to
659 Taketoshi Sano <kgh12351@nifty.ne.jp>
660 * Rewrote and simplified logger. Added the "-t" option, and made it
661 behave itself a bit better.
662 * Optional support contributed by Ben Collins <bcollins@debian.org>
663 for the kernel init chroot patch by Werner Almesberger, which
664 allows init to chroot to a new device, and umount the old one.
665 * Fixed bug that wouldn't let one chown a symlink -- it would
666 always dereference before. -beppu
667 * Fixed a bug where init could have reference already freed memory.
668 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
669 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
670 * Added (and documented) "-n" option for head
671 * Cleanup for a number of usage messages -- also
672 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
673 * Cosmetic fix to busybox.c (Don't print a comma at the
674 end of line if there are no more application names).
675 * Fixed a stupid bug in "head" option handling ("head -n"
677 * Moved commonly used functions "xmalloc()" and "exit()"
678 to utility.c (with proper #ifdef's).
679 * Created a tiny tail implementation, removing -c, -q, -v, and making
680 tail -f work only with a single file. This reduced tail from 6k to
681 2.4k. The bigger/more featured tail can still be had by disabling
682 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
683 * Ping now falls back to doing the right thing if /etc/protocols
685 * Fixed mount and umount. Previously they could leak loop device
686 allocations, causing the system to quickly run out. Fix for umount
687 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
688 * ls formatting on eight charactor user names fixed by
689 Randolph Chung <tausq@debian.org>.
690 * cp could, when copying symlinks, change permissions of the
691 files pointed to by the symlinks.
692 * Several fixes from Pavel Roskin <proski@gnu.org>:
693 - `chown' with 1 argument displayed the error incorrectly
694 - `fdflush', `length' and `printf' crashed if run without arguments
695 - `fdflush' tried to flush itself using *argv
696 - added "skip" and "seek" to dd.
697 - ls no longer messus up output when combining files and
698 directories on the command line
699 * swapoff -a was not working. Now it is.
700 * init did not cleanly unmount filesystems on reboot. Now it does.
701 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
703 * Some architectures (PowerPc) assume chars are unsigned, so they could
704 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
705 * Began converting error handling to use some common routines
707 * syslogd now has better message handling and ignores SIGHUP.
708 * install.sh had a bug preventing installation to the specified
709 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
710 * You can now spefify alternative strip commands -- change
711 also from Gilbert Coville.
717 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
718 by Edward Betts <edward@debian.org>
719 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
720 type commands (file in a directory to another directory) from
722 * Fixed a logger bug that caused garbage to be written to the syslog
723 (unless you used busybox syslog, which hid the bug). Thanks to
724 Alex Holden <alex@linuxhacker.org> for the fix.
725 * /bin/true and /bin/false were echoing a blank line when run.
727 * mkdir -p would print an error when asked to mkdir an existing dir
728 with no interveining subdirectories.
729 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
730 * and support in umount for loop
731 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
732 <bcollins@debian.org>
733 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
734 * fullWrite() not only if BB_TAR is defined, but also
735 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
736 * add some compiler optimizations to further reduce executable size
737 (as a side note, on my machines the largest code is generated
738 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
740 * Compile now won't fail if busybox.def.h defines
741 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
742 referenced, but not compiled)
743 * Fixed a bug in setting TERM for serial console support. TERM now
744 defaults to "ansi" for serial consoles.
745 * Fixed a bug in handling the CONSOLE env. variable for serial
748 -Erik Andersen, Jan 15, 2000
751 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
752 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
753 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
754 for loading application character maps for Unicode fonts.
755 * Major init re-work. init now supports inittab (slightly different
756 but similar to sysvinit), allowing me to get all the policy out of
757 init and into the conf file. It works just fine without inittab
758 being present, but if you dont like the default behavior you can
759 now do something about it. Init is much cleaner as a result.
760 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
761 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
762 * failure of 'logger -p'. -erik Added the -s option to du -beppu
763 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
764 with the 2.0.x Linux kernel.
765 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
767 * Grep -i previously failed on UPPER CASE patterns due to a silly
768 regexp implementation bug that is now fixed.
769 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
770 * Fixed a bug where tar would not set the user and group on device
772 * Fixed a bug where tar would not restore the time to files. Fixed a
773 * major security problem with tar -- it changed ownership
774 of any file pointed to by a symlink to 777 (like say libc....)
776 * cp and mv were very broken when moving directories. I have rewritten
777 them so they should now work as expected.
778 * sed now supports addresses (numeric or regexp, with negation) and
779 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
780 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
781 * Some cosmetic fixes to ls output formatting to make it behave more
783 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
784 * <fwv@myrtle.lahn.de>:
785 - Added gunzip -t, removed gunzip.c dead code,
786 - fixed several typos
787 - Glibc 2.0.7 and libc5 compile fixes
788 * Fixed a bug where 'mknod --help' would segfault.
791 -Erik Andersen, Jan 07, 2000
794 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
795 <tausq@debian.org>. 3 items off the TODO list!
796 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
797 * tail from GNU textutils-1.19, but adjusted
798 to suit my evil purposes. Costs 6k. I'll make it smaller
800 * on reboot, init called 'umount -a -n', which caused errors
801 when BB_MTAB was not enabled. Changed to 'umount -a', which does
803 * init will now try to run /sbin/getty if it is present (for easy
804 integration with the about-to-be-released tinylogin.)
805 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
806 * -l' was failing on long directories, since my_getid was leaking
807 one file descriptor per file. Oops.
808 * Fixed rebooting from init. I'd accidently left some debugging code
810 which blocked reboots.
811 * Fixed reboot, halt (and added poweroff) such that they handle it when
812 init is not at PID 1 (like when running in an initrd).
813 * Added a prelinary du implementation. Some parameter parsing
814 stuff still needs to be added. -beppu (John Beppu
816 * Implemented tee. -beppu Implemented head. -beppu
818 -Erik Andersen, Dec 10, 1999
821 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
823 * df will not exit on error, but will stat all mounted filesystems.
824 * Fixed tar so uid/gid/permissions on extracted tarballs will be
826 * Fixed find -name so it properly uses shell wildcard patterns
827 (i.e. `*', `?', and `[]') instead of regular expressions, which
828 was causing some confusing and unexpected behavior.
829 * Added klogd to syslogd, so now the log will contain both system and
831 * syslogd now creates the /dev/log socket to make sure it is there, and
832 is actually a socket with the right permissions.
833 * I've taken a first step to making busybox not need the /proc
834 filesystem. Most apps don't need it. Those that _require_ it,
835 will complain if you enable them when you disable
836 BB_FEATURE_USE_PROCFS.
838 -Erik Andersen, Dec 5, 1999
841 * Wrote a micro syslogd, and a logger util (to log things to the syslog
842 from the command line or scripts) With both compiled in, costs 4k.
843 * Fixed 'make install' so symlinks are installed in their proper
844 * locations. Changed the build system slightly so that features can
846 or disabled from the busybox.defs.h header file, without trying to
847 compile in a source file named after that featue (unless that file
849 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
850 * -r' both work. dd now properly handles input beyond 1 block from
851 * stdin. Fixed a bug where tar unpacked everything a directories.
853 from createPath into mkdir where it belonged, thereby making tar
855 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
857 last file in the list.
858 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
860 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
861 are presented properly.
865 -Erik Andersen, Nov 25, 1999
868 * fixed dd so it properly defaults to stdin and stdout when no
869 if= and of= are set (fix thanks to Eric Delaunay).
870 * Don't try to close the file descriptor of a pipein tar. (fix also
873 * Made createPath be quiet (again thanks to Eric Delaunay). If
874 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
875 command you define it as will be run if the init script exits.
876 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
877 * NFS support added to mount by Eric Delaunay. It costs 10k when
879 in, but that is still a big win for those that use NFS.
880 * Made 'rm -f' be silent for non-existant files (thanks to Eric
881 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
883 and acts as god intended gunzip and zcat to act. They answer
884 --help and obey the '-c' flag.
885 * Fixed a bug in mv which caused it to not move files when the
888 * Fixed a decimal-instead-of-octal bug causing mkdir to make
890 with very wrong permissions.
891 * chmod would overwrite file permissions instead of modifying them.
892 Now it properly modifies permissions.
893 * Init now sends warnings destined for the console to /dev/console to
895 they show up on whatever the active console it. Otherwise
896 important messages (for example that the system is rebooting) were
897 not seen when switched to a different VT.
899 -Erik Andersen, Nov 17, 1999
902 * gzip now obeys the principle of least surprise and acts like god
904 (i.e. it accepts a file name, answers --help, and obeys the '-c'
905 flag and only then outputs to stdout).
906 * Fixed more.c to compile autowidth on sparc and set initial winsize
907 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
909 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
910 * tar now accepts --help chmod, chown, and chgrp usage now works
911 * General usage (i.e. --help) cleanups for most apps umount now parses
912 * options correctly tar can now unpack tarballs containing device
914 sockets, and fifos (though it can't pack them up) thanks to Matt
915 Porter. Creating archives containing these is still left to the
917 * fixed up the license in more.c to properly point to Bruce Perens.
919 -Erik Andersen, Nov 11, 1999
922 * ls -l now displays link names outside the current directory,
923 Patch thanks to Eric Delaunay
924 * init now properly handles sparc serial consoles and does a
925 better job of finding the real console device rather than using
926 /dev/console which doesn't support job control. Patch also thanks
928 * more started to read from stdin after the last file was finished, and
929 options were not parsed correctly (fix thanks to Eric Delaunay).
930 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
931 * rm wouldn't remove a symlink unless the symlink was valid. This was
932 a side effect of the busybox 0.32 recursiveAction() fix. Things
933 should now work correctly.
934 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
935 * it does. sed was appending a \n to the end of lines with
937 Now it doesn't do that.
938 * ls -l now bypasses libc6 nss when displaying user/group names.
939 Now uses my_getpwuid and my_getgrgid.
941 -Erik Andersen, Nov 8, 1999
944 * Fixed a bug where init could hang instead of rebooting.
945 * Removed some debugging noise from init.c
946 * Fixed ln so it works now (it was very broken).
947 * Fixed df so it won't segfault when there is no /etc/fstab,
948 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
949 is not installed (since they cannot fixup "/dev/root" to
950 state the real root device name)
951 * merged some redundant code from mtab.c/df.c into utility.c
953 -Erik Andersen, Nov 5, 1999
956 * More changes -- many thanks to Lineo for paying me to work on
957 busybox. If you have any problems please let me know ASAP at
958 andersen@lineo.com or andersee@debian.org
959 * usage() now prints the BusyBox version. This will help folks
960 realize that they are not in Kansas anymore.
961 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
962 * arguments. Now it doesn't do that. kill wasn't properly accepting
963 * signal names. It does now. Added new apps chvt and deallocvt (I
964 * should probably add open) Major rewrite of init.c. Code is now
965 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
966 * with full regular expressions!). Fixed a stupid seg-fault in sync
967 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
968 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
969 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
970 * cost of ~1.5k and the need for a rw /etc)
971 folks to use a real /etc/mtab file instead of a symlink to
972 /proc/mounts. mount, and umount will add/remove entries and df
973 will now use /etc/mtab if BB_MTAB is defined.
974 * Fixed a nice bug in recursiveAction() which caused it to infinitely
975 hunt through /proc/../fd/* creating new file descriptors if it
976 followed the /dev/fd link over to /proc. recursiveAction() now
977 lstat's the file when followLinks==FALSE so it won't follow links
978 as the name suggests. Fix thanks to Matt Porter
982 -Erik Andersen, Nov 4, 1999
985 * I added a changelog for version 0.30. adjusted find internals to
986 * make it smaller, and removed
988 * Fixed a segfault in ps when /etc/passwd or /etc/group
989 are absent. Now will warn you and carry on.
990 * Added in optional _real_ regular expression support (to be
991 the basis for a future sed utility). When compiled in it adds
992 3.9k, but makes grep much more capable.
993 * Checked out using nftw(3) for recursive stuff, but unfortunatly
994 it wasn't supported before GNU libc 2.1, and some folks use glibc
995 2.0.7 since it is much smaller than that latest and greatest.

1000 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
1001 paying me to make these updates. If you have any problems with busybox,
1002 or notice any bugs -- please let me know so I can fix it. These
1006 * busybox can now invoke apps in two ways: via symlinks to the
1007 busybox binary, and as 'busybox [function] [arguments]...'
1008 * When invoked as busybox, the list of currently compiled in
1009 functions is printed out (no this is not bloat -- the list has
1010 to be there anyway to map invocation name to function).
1011 * busybox no longer parses command lines for apps or displays their
1012 usage info. Each app gets to handle (or not handle) this for
1014 * Eliminated monadic, dyadic, descend, block_device, and
1015 postprocess. It was cumbersome to have so many programs
1016 cobbled together in this way. Without them, the app is much
1018 * All shared code now lives in utility.c, and is properly
1019 ifdef'ed to be only included for those apps requiring it.
1020 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
1021 so now each app has the function prototype of (da-dum): extern
1022 int foo_main(int argc, char** argv); which speeds integration
1024 * Adjusted the Makefile to make it easier to
1025 {en|dis}able debugging.
1026 * Changed default compiler optimization to -Os
1027 (optimize for smaller binaries).
1030 * To cope with the new app function prototype and the removal of
1031 monadic, dyadic, etc, the following apps were re-written:
1032 * cat - Works same as always. chgrp, chmod, chown -
1033 * rewrite. Combined into a single
1034 source file. Absorbed patches from Enrique Zanardi
1035 <ezanard@debian.org> that removes the dependency on
1036 libc6 libnss* libraries.
1037 * cp - Can now do 'cp -a' can can copy devices,
1038 pipes, symlinks, as well as recursive or non-recursive
1040 * fdflush - adjusted to remove dependancy on struct
1041 * FileInfo. find - Now includes some basic regexp matching
1042 which will be the basic of a future mini-sed.
1043 * ln - Same functionality. mkdir - Added -p flag to
1044 * feature set. mv - rewrite. rm - Added -f flag to
1045 * feature set. rmdir - Same functionality. swapon,
1046 * swapoff - Combined into a single binary. No longer
1047 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
1049 * touch - Same functionality. date - adjusted with a patch
1050 * from Matthew Grant <grantma@anathoth.gen.nz>
1051 to accomodate glibc timezone support. I then ripped out GNU
1053 * mkswap -- new version merged from util-linux. Can now make
1055 * Replaced the old and star, unstar, and tarcat with the tar
1056 implementation from sash. Now tar behaves as god intended it
1057 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
1058 * dd -- rewritten. Can with with files, stdin, stdout. Added the
1059 * following new apps: loadfont -- added from debian boot floppies
1060 * chroot -- added based on a patch from Paolo Molaro
1061 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
1062 * simple strings ps -- I just wrote it. Has _no_ options at all,
1063 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
1065 internationalization and such to make them smaller.
1066 * sfdisk -- Added from util-linux (minus
1067 * internationalization and such). Probably some other
1068 * changes that I forgot to document...
1070 -Erik Andersen, Oct 20, 1999
1073 This version was a messy pre-alpha. stay away or it will bite you.
1074 -Erik Andersen, Sep 24, 1999
1077 mini-netcat (mnc) rewritten.
1080 Mount now supports -a, and -t auto.
1081 Mount now updates mtab correctly for 'ro'.
1082 More checks screen rows size, outputs bytes percentage.
1083 Printf added as module.
1085 Touch now creates files. -c option for no create.
