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

560 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
561 paying me to make these updates. If you have any problems with busybox,
562 or notice any bugs -- please let me know so I can fix it. These
566 * busybox can now invoke apps in two ways: via symlinks to the
567 busybox binary, and as 'busybox [function] [arguments]...'
568 * When invoked as busybox, the list of currently compiled in
569 functions is printed out (no this is not bloat -- the list has
570 to be there anyway to map invocation name to function).
571 * busybox no longer parses command lines for apps or displays their
572 usage info. Each app gets to handle (or not handle) this for
574 * Eliminated monadic, dyadic, descend, block_device, and
575 postprocess. It was cumbersome to have so many programs
576 cobbled together in this way. Without them, the app is much
578 * All shared code now lives in utility.c, and is properly
579 ifdef'ed to be only included for those apps requiring it.
580 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
581 so now each app has the function prototype of (da-dum): extern
582 int foo_main(int argc, char** argv); which speeds integration
584 * Adjusted the Makefile to make it easier to
585 {en|dis}able debugging.
586 * Changed default compiler optimization to -Os
587 (optimize for smaller binaries).
590 * To cope with the new app function prototype and the removal of
591 monadic, dyadic, etc, the following apps were re-written:
592 * cat - Works same as always. chgrp, chmod, chown -
593 * rewrite. Combined into a single
594 source file. Absorbed patches from Enrique Zanardi
595 <ezanard@debian.org> that removes the dependency on
596 libc6 libnss* libraries.
597 * cp - Can now do 'cp -a' can can copy devices,
598 pipes, symlinks, as well as recursive or non-recursive
600 * fdflush - adjusted to remove dependancy on struct
601 * FileInfo. find - Now includes some basic regexp matching
602 which will be the basic of a future mini-sed.
603 * ln - Same functionality. mkdir - Added -p flag to
604 * feature set. mv - rewrite. rm - Added -f flag to
605 * feature set. rmdir - Same functionality. swapon,
606 * swapoff - Combined into a single binary. No longer
607 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
609 * touch - Same functionality. date - adjusted with a patch
610 * from Matthew Grant <grantma@anathoth.gen.nz>
611 to accomodate glibc timezone support. I then ripped out GNU
613 * mkswap -- new version merged from util-linux. Can now make
615 * Replaced the old and star, unstar, and tarcat with the tar
616 implementation from sash. Now tar behaves as god intended it
617 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
618 * dd -- rewritten. Can with with files, stdin, stdout. Added the
619 * following new apps: loadfont -- added from debian boot floppies
620 * chroot -- added based on a patch from Paolo Molaro
621 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
622 * simple strings ps -- I just wrote it. Has _no_ options at all,
623 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
625 internationalization and such to make them smaller.
626 * sfdisk -- Added from util-linux (minus
627 * internationalization and such). Probably some other
628 * changes that I forgot to document...
630 -Erik Andersen, Oct 20, 1999
633 This version was a messy pre-alpha. stay away or it will bite you.
634 -Erik Andersen, Sep 24, 1999
637 mini-netcat (mnc) rewritten.
640 Mount now supports -a, and -t auto.
641 Mount now updates mtab correctly for 'ro'.
642 More checks screen rows size, outputs bytes percentage.
643 Printf added as module.
645 Touch now creates files. -c option for no create.
