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

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

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

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