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

522 * I added a changelog for version 0.30. adjusted find internals to
523 * make it smaller, and removed
525 * Fixed a segfault in ps when /etc/passwd or /etc/group
526 are absent. Now will warn you and carry on.
527 * Added in optional _real_ regular expression support (to be
528 the basis for a future sed utility). When compiled in it adds
529 3.9k, but makes grep much more capable.
530 * Checked out using nftw(3) for recursive stuff, but unfortunatly
531 it wasn't supported before GNU libc 2.1, and some folks use glibc
532 2.0.7 since it is much smaller than that latest and greatest.

537 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
538 paying me to make these updates. If you have any problems with busybox,
539 or notice any bugs -- please let me know so I can fix it. These
543 * busybox can now invoke apps in two ways: via symlinks to the
544 busybox binary, and as 'busybox [function] [arguments]...'
545 * When invoked as busybox, the list of currently compiled in
546 functions is printed out (no this is not bloat -- the list has
547 to be there anyway to map invocation name to function).
548 * busybox no longer parses command lines for apps or displays their
549 usage info. Each app gets to handle (or not handle) this for
551 * Eliminated monadic, dyadic, descend, block_device, and
552 postprocess. It was cumbersome to have so many programs
553 cobbled together in this way. Without them, the app is much
555 * All shared code now lives in utility.c, and is properly
556 ifdef'ed to be only included for those apps requiring it.
557 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
558 so now each app has the function prototype of (da-dum): extern
559 int foo_main(int argc, char** argv); which speeds integration
561 * Adjusted the Makefile to make it easier to
562 {en|dis}able debugging.
563 * Changed default compiler optimization to -Os
564 (optimize for smaller binaries).
567 * To cope with the new app function prototype and the removal of
568 monadic, dyadic, etc, the following apps were re-written:
569 * cat - Works same as always. chgrp, chmod, chown -
570 * rewrite. Combined into a single
571 source file. Absorbed patches from Enrique Zanardi
572 <ezanard@debian.org> that removes the dependency on
573 libc6 libnss* libraries.
574 * cp - Can now do 'cp -a' can can copy devices,
575 pipes, symlinks, as well as recursive or non-recursive
577 * fdflush - adjusted to remove dependancy on struct
578 * FileInfo. find - Now includes some basic regexp matching
579 which will be the basic of a future mini-sed.
580 * ln - Same functionality. mkdir - Added -p flag to
581 * feature set. mv - rewrite. rm - Added -f flag to
582 * feature set. rmdir - Same functionality. swapon,
583 * swapoff - Combined into a single binary. No longer
584 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
586 * touch - Same functionality. date - adjusted with a patch
587 * from Matthew Grant <grantma@anathoth.gen.nz>
588 to accomodate glibc timezone support. I then ripped out GNU
590 * mkswap -- new version merged from util-linux. Can now make
592 * Replaced the old and star, unstar, and tarcat with the tar
593 implementation from sash. Now tar behaves as god intended it
594 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
595 * dd -- rewritten. Can with with files, stdin, stdout. Added the
596 * following new apps: loadfont -- added from debian boot floppies
597 * chroot -- added based on a patch from Paolo Molaro
598 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
599 * simple strings ps -- I just wrote it. Has _no_ options at all,
600 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
602 internationalization and such to make them smaller.
603 * sfdisk -- Added from util-linux (minus
604 * internationalization and such). Probably some other
605 * changes that I forgot to document...

610 This version was a messy pre-alpha. stay away or it will bite you.
611 -Erik Andersen, Sep 24, 1999
614 mini-netcat (mnc) rewritten.
617 Mount now supports -a, and -t auto.
618 Mount now updates mtab correctly for 'ro'.
619 More checks screen rows size, outputs bytes percentage.
620 Printf added as module.
622 Touch now creates files. -c option for no create.
