3 * Updates to handle Linux 2.4.0 kernels (kludged around the
4 "none" entries in /proc/mounts, added a hack to make sysinfo
5 work with both old and new kernels).
6 * Fixed a nasty bug in tar when could mess up saved symlinks.
12 * Now compiles vs libc5 (which can save lots of space for
14 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
15 help messages (i.e --help). Saves 17k over a full compile.
16 * Added cut and tr from minix, since due to the license change,
17 we can now use minix code. Minix tr saves 4k.
18 * insmod now works. It costs 29k, but imagine an initrd with a
19 staticly linked busybox containing only insmod and sh, a few /dev
20 entries, and a kernel module or two... It doesn't get smaller
21 then this folks (I pity the fool that writes insmod in asm ;-).
22 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
23 * Added a mini ar archive utility, especially written for BusyBox by
24 Glenn McGrath <bug1@netconnect.com.au>
25 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
26 * Added setkeycodes, for those that have wierd keyboard buttons.
27 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
28 <ams@trillian.itslinux.org> for contributing these.
29 * Added 'grep -v' option (inverted search) and updated
30 docs accordingly. -beppu
32 * Replaced the telnet implementation with one written by
33 Tomi Ollila <too@iki.fi> It works great and costs 3k.
34 * BusyBox sh (lash) now supports being used as a standalone shell. When
35 BB_FEATURE_STANDALONE_SHELL is defined, all the busybox commands may
36 be invoked as shell internals. Best used when compiling staticly
38 * BusyBox sh (lash) internals now behave as expected wrt pipes
40 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
41 * Fixed update segfault
42 * Fixed mknod -- minor number was always 0
43 * Fixed tar option parsing, so both "tar xvf foo.tar" and
44 "tar -xvf foo.tar" now work (i.e. no "-" before options)
45 (this was very broken in 0.43).
46 * Several contributions from Randolph Chung <tausq@debian.org>.
47 * cp/mv now accepts the -f flag
48 * tail can now accept -<num> commands (e.g. -10) for better
49 compatibility with the standard tail command
50 * added a simple id implementation; doesn't support sup. groups yet
51 * logname used getlogin(3) which uses utmp. Now it doesn't.
52 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
53 * Add support for "noatime" and "nodiratime" mount flags to mount.
54 * Changed 'umount -f' to mean force, and actually use umount2.
55 * Changed 'umount -l' to mean "Do not free loop device".
56 * Fixed basename to support stripping of suffixes. Patch thanks
57 to xiong jianxin <jxiong@uiuc.edu>
58 * cp -fa now works as expected for symlinks (it didn't before)
59 * zcat now works (wasn't working since option parsing was broken)
60 * Renamed "mnc" to the more correct "nc" (for netcat).
61 * Makefile intelligence updates
62 * Changed the way init parses /etc/inittab entries to avoid problems
63 with commands that contain colons in them. Fix thanks to
64 Pavel Roskin <proski@gnu.org>
65 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
66 Fix thanks to Pavel Roskin <proski@gnu.org>
67 * Made "killall" complain (not error and exit) about processes that it
68 cannot find by name -- Pavel Roskin <proski@gnu.org>
69 * Fixed more and ps to have sensible terminal width defaults, thanks
71 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
72 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
73 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
74 * Fixed segfault caused by "touch -c"
75 * Fixed segfault caused by "rm -f"
76 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
77 and "--" support from Pavel Roskin.
78 * Fixed segfault caused by "cp -a -a" and similar abuses.
79 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
80 * "which" rewritten to use stat(). Fixes to improve its compatability
81 with traditional implementations -- Pavel Roskin.
82 * "mount" now reports errors from nfsmount() and assumes NFS mount
83 if ':' is present in the device name - Pavel Roskin
84 * Fixed exit status for killall - Pavel Roskin
85 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
86 * Fixed 'mount -a' so it works as expected.
87 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
88 * Implemented "ping -s", fixed error messages and argument parsing -
90 * Syslogd will not go to background if "-n" is given. Better help
91 and argument checking -- Pavel Roskin
92 * Fixed a small bug that could cause tar to emit warning messages
93 and not extract the first file in a directory in some cases
94 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
95 for helping track this one down.
97 * Fixed grep "Line too long" problem -- John Beppu
98 * Fixed 'grep -q -i B some_file' so it works
99 * math takes input from stdin if no args are given. -- John Beppu
100 * math was renamed to dc. Although it deviates from dc's behaviour,
101 this will probably be remedied in the future. -- John Beppu
104 -Erik Andersen, June 21, 2000
108 Previously, an erronous announcement of BusyBox 0.44 was made, so to
109 avoid possible confusion, we are skipping straight to 0.45, and calling
116 * Major update to the provided documentation.
117 * Busybox now includes a shell! It currently costs 7.5 k (plus an
118 additional 2.5 k if you compile in command line editing). Handles
119 job control, has the usual set of builtins, and does everything
120 except for handling programming statements (if, while, etc...)
121 * Busybox can now work perfectly when /proc is disabled, thereby
122 saving a bunch of memory (kernel /proc support is not thin). This
123 is done by making use of some nice kernel patches I wrote up to
124 support the features that busybox requires and that /proc usually
125 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
126 patch your kernel with the devps patch in the kernel-patches/
128 * Wrote basename, dirname, killall, and uptime.
129 * tar has been completely rewritten by me. Both tar creation and
130 extraction are now well behaved. Costs 7.6k with all optional
131 tar features enabled, and 5k for just tar extraction support.
132 * Added freeramdisk, which will free up all memory associated
133 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
134 and then adjusted a bit by me.
135 * Added tr from John Lombardo <john@deltanet.com>
136 * Added echo and test (from me).
137 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
138 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
139 * Several fixes from Pavel Roskin <proski@gnu.org>:
140 - When `tail' fails to open a file it now exits.
141 - When `syslogd' is given the `-n' option it should still use
142 fork() for running klogd.
143 * nslookup types are now changed to u_int32_t (instead of uint32_t)
144 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
145 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
146 to count hard-linked files more then once). Many thanks to
147 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
148 * Removed /proc dependancies for init and free (while maintaining
149 exactly the same functionality). /proc takes up 90k of kernel
150 space, so it is nice to avoid using it at all costs.
151 * init no longer tries to mount /proc (unless there is less the 1 meg
152 free). Use of /proc (or not) is policy that should be set up in
153 /etc/fstab (or in hardcoded scripts), not in init.
154 * Fixed rebooting when init runs as an initrd.
155 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
156 - update.c rewritten to look more like update-2.11
157 - moveed the inode hash out of du.c and into utility.c to make
158 it a common resource that can be used by other apps.
159 - cp_mv.c now checks inodes to see if a source and dest are
160 the same, and prints an error (instead of endlessly looping).
161 - mv now attempts to do a rename, and will fall back to doing
162 a copy only if the rename fails.
163 - Syslogd now supports multiple concurrent connections
164 * Several fixes from Pavel Roskin <proski@gnu.org>:
165 - Fixes to sort. Removed "-g", fixed and added "-r"
166 - Fixes to the makefile for handling "strip"
167 * An initial telnet implementation was added by
168 Randolph Chung <tausq@debian.org>.
169 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
170 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
171 to match the terminal (defaults to width=79 when this is off).
172 * ps now accepts (and ignores) all options except for "--help" (which
173 as would be expected displays help).
174 * Fixed mount'ing loop devices when the filesystem type was not
175 specified. It used to revert to non-loop after the first try.
176 * all mallocs now use xmalloc (and so are OOM error safe), and
177 the common error handling saves a few bytes. Thanks to
178 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
179 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
180 * Fix symlink following bug in chmod -R and friends.
181 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
182 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
191 * Fairly massive restructuring of umount.c to deal with remounting
192 busy devices read-only. Adds a -r option to control that; it is
193 optionally compiled in with BB_FEATURE_REMOUNT
194 * Added a bunch of functions to mtab.c to interact with the
195 {get,set,end}mntent interface; as it turns out, those functions do
196 not appear to be re-entrant, and that causes a lot of problems with
197 the way umount was originally written.
198 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
199 to be more consistent with sysvinit
200 * Changes to init.c to use the new -r option to umount. Also increased
201 the sleep time between the time the TERM and KILL signals are sent
206 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
207 extensively rewritten from the original cp.c.
208 * Fixed cp and mv so if the source and destination are a the
209 same directory it will print an error and continue.
210 * Also added a warning message to the `mv' usage string saying that
211 this is not GNU mv, and it will break hard links. cp also breaks
213 * ln.c: implemented `-n' switch, no-deref symlinks.
214 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
215 * name buffer overrun guards to prevent future crashes.
216 - Always check exit status.
217 - Purge all use of `creat()', replace with `open()'.
219 - recursiveAction was overriding the value of followLinks thus
221 - isDirectory now takes a followLinks boolean, updated all callers
222 - copyFile had the followLinks logic reversed.
223 * messages.c: New file. Put common error message strings all in
224 one place in an attempt to shrink the binary a little.
229 * changed fsck_minix.c to reduce its .bss size significantly
231 * Made tar creation support in busybox tar optional. You no longer
232 * _have_ to put a "-" in front of tar options. Tar could inadvertently
233 * change permissions and ownership on
234 certain directories pointed to by symlinks.
235 * Made grep and grep -h do the right thing wrt printing
236 the file name (it failed to print files names in many cases).
237 * Fix a namespace aliasing problem wereby if du was built in, the
238 symlink for both du and dutmp would be installed, or then rm was
239 built in, the symlinks for both rm and rmmod would be installed.
240 * Added a closelog() to init.c after loging -- fix thanks to
241 Taketoshi Sano <kgh12351@nifty.ne.jp>
242 * Rewrote and simplified logger. Added the "-t" option, and made it
243 behave itself a bit better.
244 * Optional support contributed by Ben Collins <bcollins@debian.org>
245 for the kernel init chroot patch by Werner Almesberger, which
246 allows init to chroot to a new device, and umount the old one.
247 * Fixed bug that wouldn't let one chown a symlink -- it would
248 always dereference before. -beppu
249 * Fixed a bug where init could have reference already freed memory.
250 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
251 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
252 * Added (and documented) "-n" option for head
253 * Cleanup for a number of usage messages -- also
254 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
255 * Cosmetic fix to busybox.c (Don't print a comma at the
256 end of line if there are no more application names).
257 * Fixed a stupid bug in "head" option handling ("head -n"
259 * Moved commonly used functions "xmalloc()" and "exit()"
260 to utility.c (with proper #ifdef's).
261 * Created a tiny tail implementation, removing -c, -q, -v, and making
262 tail -f work only with a single file. This reduced tail from 6k to
263 2.4k. The bigger/more featured tail can still be had by disabling
264 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
265 * Ping now falls back to doing the right thing if /etc/protocols
267 * Fixed mount and umount. Previously they could leak loop device
268 allocations, causing the system to quickly run out. Fix for umount
269 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
270 * ls formatting on eight charactor user names fixed by
271 Randolph Chung <tausq@debian.org>.
272 * cp could, when copying symlinks, change permissions of the
273 files pointed to by the symlinks.
274 * Several fixes from Pavel Roskin <proski@gnu.org>:
275 - `chown' with 1 argument displayed the error incorrectly
276 - `fdflush', `length' and `printf' crashed if run without arguments
277 - `fdflush' tried to flush itself using *argv
278 - added "skip" and "seek" to dd.
279 - ls no longer messus up output when combining files and
280 directories on the command line
281 * swapoff -a was not working. Now it is.
282 * init did not cleanly unmount filesystems on reboot. Now it does.
283 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
285 * Some architectures (PowerPc) assume chars are unsigned, so they could
286 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
287 * Began converting error handling to use some common routines
289 * syslogd now has better message handling and ignores SIGHUP.
290 * install.sh had a bug preventing installation to the specified
291 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
292 * You can now spefify alternative strip commands -- change
293 also from Gilbert Coville.
299 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
300 by Edward Betts <edward@debian.org>
301 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
302 type commands (file in a directory to another directory) from
304 * Fixed a logger bug that caused garbage to be written to the syslog
305 (unless you used busybox syslog, which hid the bug). Thanks to
306 Alex Holden <alex@linuxhacker.org> for the fix.
307 * /bin/true and /bin/false were echoing a blank line when run.
309 * mkdir -p would print an error when asked to mkdir an existing dir
310 with no interveining subdirectories.
311 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
312 * and support in umount for loop
313 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
314 <bcollins@debian.org>
315 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
316 * fullWrite() not only if BB_TAR is defined, but also
317 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
318 * add some compiler optimizations to further reduce executable size
319 (as a side note, on my machines the largest code is generated
320 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
322 * Compile now won't fail if busybox.def.h defines
323 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
324 referenced, but not compiled)
325 * Fixed a bug in setting TERM for serial console support. TERM now
326 defaults to "ansi" for serial consoles.
327 * Fixed a bug in handling the CONSOLE env. variable for serial
330 -Erik Andersen, Jan 15, 2000
333 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
334 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
335 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
336 for loading application character maps for Unicode fonts.
337 * Major init re-work. init now supports inittab (slightly different
338 but similar to sysvinit), allowing me to get all the policy out of
339 init and into the conf file. It works just fine without inittab
340 being present, but if you dont like the defautl behavior you can
341 now do something about it. Init is much cleaner as a result.
342 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
343 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
344 * failure of 'logger -p'. -erik Added the -s option to du -beppu
345 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
346 with the 2.0.x Linux kernel.
347 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
349 * Grep -i previously failed on UPPER CASE patterns due to a silly
350 regexp implementation bug that is now fixed.
351 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
352 * Fixed a bug where tar would not set the user and group on device
354 * Fixed a bug where tar would not restore the time to files. Fixed a
355 * major security problem with tar -- it changed ownership
356 of any file pointed to by a symlink to 777 (like say libc....)
358 * cp and mv were very broken when moving directories. I have rewritten
359 them so they should now work as expected.
360 * sed now supports addresses (numeric or regexp, with negation) and
361 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
362 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
363 * Some cosmetic fixes to ls output formatting to make it behave more
365 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
366 * <fwv@myrtle.lahn.de>:
367 - Added gunzip -t, removed gunzip.c dead code,
368 - fixed several typos
369 - Glibc 2.0.7 and libc5 compile fixes
370 * Fixed a bug where 'mknod --help' would segfault.
373 -Erik Andersen, Jan 07, 2000
376 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
377 <tausq@debian.org>. 3 items off the TODO list!
378 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
379 * tail from GNU textutils-1.19, but adjusted
380 to suit my evil purposes. Costs 6k. I'll make it smaller
382 * on reboot, init called 'umount -a -n', which caused errors
383 when BB_MTAB was not enabled. Changed to 'umount -a', which does
385 * init will now try to run /sbin/getty if it is present (for easy
386 integration with the about-to-be-released tinylogin.)
387 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
388 * -l' was failing on long directories, since my_getid was leaking
389 one file descriptor per file. Oops.
390 * Fixed rebooting from init. I'd accidently left some debugging code
392 which blocked reboots.
393 * Fixed reboot, halt (and added poweroff) such that they handle it when
394 init is not at PID 1 (like when running in an initrd).
395 * Added a prelinary du implementation. Some parameter parsing
396 stuff still needs to be added. -beppu (John Beppu
398 * Implemented tee. -beppu Implemented head. -beppu
400 -Erik Andersen, Dec 10, 1999
403 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
405 * df will not exit on error, but will stat all mounted filesystems.
406 * Fixed tar so uid/gid/permissions on extracted tarballs will be
408 * Fixed find -name so it properly uses shell wildcard patterns
409 (i.e. `*', `?', and `[]') instead of regular expressions, which
410 was causing some confusing and unexpected behavior.
411 * Added klogd to syslogd, so now the log will contain both system and
413 * syslogd now creates the /dev/log socket to make sure it is there, and
414 is actually a socket with the right permissions.
415 * I've taken a first step to making busybox not need the /proc
416 filesystem. Most apps don't need it. Those that _require_ it,
417 will complain if you enable them when you disable
418 BB_FEATURE_USE_PROCFS.
420 -Erik Andersen, Dec 5, 1999
423 * Wrote a micro syslogd, and a logger util (to log things to the syslog
424 from the command line or scripts) With both compiled in, costs 4k.
425 * Fixed 'make install' so symlinks are installed in their proper
426 * locations. Changed the build system slightly so that features can
428 or disabled from the busybox.defs.h header file, without trying to
429 compile in a source file named after that featue (unless that file
431 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
432 * -r' both work. dd now properly handles input beyond 1 block from
433 * stdin. Fixed a bug where tar unpacked everything a directories.
435 from createPath into mkdir where it belonged, thereby making tar
437 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
439 last file in the list.
440 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
442 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
443 are presented properly.
447 -Erik Andersen, Nov 25, 1999
450 * fixed dd so it properly defaults to stdin and stdout when no
451 if= and of= are set (fix thanks to Eric Delaunay).
452 * Don't try to close the file descriptor of a pipein tar. (fix also
455 * Made createPath be quiet (again thanks to Eric Delaunay). If
456 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
457 command you define it as will be run if the init script exits.
458 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
459 * NFS support added to mount by Eric Delaunay. It costs 10k when
461 in, but that is still a big win for those that use NFS.
462 * Made 'rm -f' be silent for non-existant files (thanks to Eric
463 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
465 and acts as god intended gunzip and zcat to act. They answer
466 --help and obey the '-c' flag.
467 * Fixed a bug in mv which caused it to not move files when the
470 * Fixed a decimal-instead-of-octal bug causing mkdir to make
472 with very wrong permissions.
473 * chmod would overwrite file permissions instead of modifying them.
474 Now it properly modifies permissions.
475 * Init now sends warnings destined for the console to /dev/console to
477 they show up on whatever the active console it. Otherwise
478 important messages (for example that the system is rebooting) were
479 not seen when switched to a different VT.
481 -Erik Andersen, Nov 17, 1999
484 * gzip now obeys the principle of least surprise and acts like god
486 (i.e. it accepts a file name, answers --help, and obeys the '-c'
487 flag and only then outputs to stdout).
488 * Fixed more.c to compile autowidth on sparc and set initial winsize
489 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
491 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
492 * tar now accepts --help chmod, chown, and chgrp usage now works
493 * General usage (i.e. --help) cleanups for most apps umount now parses
494 * options correctly tar can now unpack tarballs containing device
496 sockets, and fifos (though it can't pack them up) thanks to Matt
497 Porter. Creating archives containing these is still left to the
499 * fixed up the license in more.c to properly point to Bruce Perens.
501 -Erik Andersen, Nov 11, 1999
504 * ls -l now displays link names outside the current directory,
505 Patch thanks to Eric Delaunay
506 * init now properly handles sparc serial consoles and does a
507 better job of finding the real console device rather than using
508 /dev/console which doesn't support job control. Patch also thanks
510 * more started to read from stdin after the last file was finished, and
511 options were not parsed correctly (fix thanks to Eric Delaunay).
512 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
513 * rm wouldn't remove a symlink unless the symlink was valid. This was
514 a side effect of the busybox 0.32 recursiveAction() fix. Things
515 should now work correctly.
516 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
517 * it does. sed was appending a \n to the end of lines with
519 Now it doesn't do that.
520 * ls -l now bypasses libc6 nss when displaying user/group names.
521 Now uses my_getpwuid and my_getgrgid.
523 -Erik Andersen, Nov 8, 1999
526 * Fixed a bug where init could hang instead of rebooting.
527 * Removed some debugging noise from init.c
528 * Fixed ln so it works now (it was very broken).
529 * Fixed df so it won't segfault when there is no /etc/fstab,
530 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
531 is not installed (since they cannot fixup "/dev/root" to
532 state the real root device name)
533 * merged some redundant code from mtab.c/df.c into utility.c
535 -Erik Andersen, Nov 5, 1999
538 * More changes -- many thanks to Lineo for paying me to work on
539 busybox. If you have any problems please let me know ASAP at
540 andersen@lineo.com or andersee@debian.org
541 * usage() now prints the BusyBox version. This will help folks
542 realize that they are not in Kansas anymore.
543 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
544 * arguments. Now it doesn't do that. kill wasn't properly accepting
545 * signal names. It does now. Added new apps chvt and deallocvt (I
546 * should probably add open) Major rewrite of init.c. Code is now
547 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
548 * with full regular expressions!). Fixed a stupid seg-fault in sync
549 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
550 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
551 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
552 * cost of ~1.5k and the need for a rw /etc)
553 folks to use a real /etc/mtab file instead of a symlink to
554 /proc/mounts. mount, and umount will add/remove entries and df
555 will now use /etc/mtab if BB_MTAB is defined.
556 * Fixed a nice bug in recursiveAction() which caused it to infinitely
557 hunt through /proc/../fd/* creating new file descriptors if it
558 followed the /dev/fd link over to /proc. recursiveAction() now
559 lstat's the file when followLinks==FALSE so it won't follow links
560 as the name suggests. Fix thanks to Matt Porter
564 -Erik Andersen, Nov 4, 1999
567 * I added a changelog for version 0.30. adjusted find internals to
568 * make it smaller, and removed
570 * Fixed a segfault in ps when /etc/passwd or /etc/group
571 are absent. Now will warn you and carry on.
572 * Added in optional _real_ regular expression support (to be
573 the basis for a future sed utility). When compiled in it adds
574 3.9k, but makes grep much more capable.
575 * Checked out using nftw(3) for recursive stuff, but unfortunatly
576 it wasn't supported before GNU libc 2.1, and some folks use glibc
577 2.0.7 since it is much smaller than that latest and greatest.
579 -Erik Andersen, Oct 21, 1999
582 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
583 paying me to make these updates. If you have any problems with busybox,
584 or notice any bugs -- please let me know so I can fix it. These
588 * busybox can now invoke apps in two ways: via symlinks to the
589 busybox binary, and as 'busybox [function] [arguments]...'
590 * When invoked as busybox, the list of currently compiled in
591 functions is printed out (no this is not bloat -- the list has
592 to be there anyway to map invocation name to function).
593 * busybox no longer parses command lines for apps or displays their
594 usage info. Each app gets to handle (or not handle) this for
596 * Eliminated monadic, dyadic, descend, block_device, and
597 postprocess. It was cumbersome to have so many programs
598 cobbled together in this way. Without them, the app is much
600 * All shared code now lives in utility.c, and is properly
601 ifdef'ed to be only included for those apps requiring it.
602 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
603 so now each app has the function prototype of (da-dum): extern
604 int foo_main(int argc, char** argv); which speeds integration
606 * Adjusted the Makefile to make it easier to
607 {en|dis}able debugging.
608 * Changed default compiler optimization to -Os
609 (optimize for smaller binaries).
612 * To cope with the new app function prototype and the removal of
613 monadic, dyadic, etc, the following apps were re-written:
614 * cat - Works same as always. chgrp, chmod, chown -
615 * rewrite. Combined into a single
616 source file. Absorbed patches from Enrique Zanardi
617 <ezanard@debian.org> that removes the dependency on
618 libc6 libnss* libraries.
619 * cp - Can now do 'cp -a' can can copy devices,
620 pipes, symlinks, as well as recursive or non-recursive
622 * fdflush - adjusted to remove dependancy on struct
623 * FileInfo. find - Now includes some basic regexp matching
624 which will be the basic of a future mini-sed.
625 * ln - Same functionality. mkdir - Added -p flag to
626 * feature set. mv - rewrite. rm - Added -f flag to
627 * feature set. rmdir - Same functionality. swapon,
628 * swapoff - Combined into a single binary. No longer
629 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
631 * touch - Same functionality. date - adjusted with a patch
632 * from Matthew Grant <grantma@anathoth.gen.nz>
633 to accomodate glibc timezone support. I then ripped out GNU
635 * mkswap -- new version merged from util-linux. Can now make
637 * Replaced the old and star, unstar, and tarcat with the tar
638 implementation from sash. Now tar behaves as god intended it
639 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
640 * dd -- rewritten. Can with with files, stdin, stdout. Added the
641 * following new apps: loadfont -- added from debian boot floppies
642 * chroot -- added based on a patch from Paolo Molaro
643 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
644 * simple strings ps -- I just wrote it. Has _no_ options at all,
645 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
647 internationalization and such to make them smaller.
648 * sfdisk -- Added from util-linux (minus
649 * internationalization and such). Probably some other
650 * changes that I forgot to document...

655 This version was a messy pre-alpha. stay away or it will bite you.
656 -Erik Andersen, Sep 24, 1999
659 mini-netcat (mnc) rewritten.
662 Mount now supports -a, and -t auto.
663 Mount now updates mtab correctly for 'ro'.
664 More checks screen rows size, outputs bytes percentage.
665 Printf added as module.
667 Touch now creates files. -c option for no create.
