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

273 install the /etc/nsswitch.conf configuration file and the required
274 libnss_* libraries. Adds 1.5k. You can now, also, disable this,
275 causing busybox to use the system's pwd.h and grp.h functions.
278 -Erik Andersen, 27 January 2001
282 * Glenn McGrath -- tar now supports uncompressing tar files,
283 define BB_FEATURE_TAR_GZIP to use the -z option.

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

315 precedence over applets unless BB_FEATURE_SH_BUILTINS_ALWAYS_WIN
316 * Gaute B Strokkenes <gs234@cam.ac.uk> -- applets found using a
317 binary search instead of linear search. Much faster!
318 * new applets: cmp readlink
319 * Mark Whitley -- Removed advertising clause of Berkeley license
320 according to decision by the Regents of the University of
321 California; included reference
322 * tail's confusing special treatment of single digit options removed;

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

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

371 * Fixed tar handling of stdin and stdout
372 * Renamed "internal.h" to the more sensible "busybox.h"
373 * Preliminary support for GNU HURD.
374 * Updated my devps and devmtab kernel patches for the latest 2.2.x
375 kernel, for those wanting to go proc-less.
376 * Tons of other bugfixes.
379 -Erik Andersen, 25 September 2000
384 * Better portability. Now should compile cleanly with libc5,
385 GNU libc 2.0 and 2.1, and various Linux kernels including
386 2.0.x, 2.2.x, and to 2.4.0-test*. (patch for 2.4.x kernels
387 to make /proc/mounts behave included in the kernel-patches dir).
388 * Fixed a _horrible_ bug where 'tar -tvf' could unlink
389 local files that matched tarball contents!!! Fix thanks
390 to Marius Groeger <mgroeger@sysgo.de>
391 * Fixed a nasty bug in tar when could mess up saved symlinks.
392 * Fixed tar creation support when reading from stdin ('tar -cf - . ')
393 thanks to Daniel Quinlan <quinlan@transmeta.com>
394 * Updates to handle Linux 2.4.0 kernels (kludged around the
395 "none" entries in /proc/mounts, added a hack to make sysinfo
396 work with both old and new kernels).
397 * Fixed insmod module option parsing for options lacking an '='.
398 Fix thanks to Marc Nijdam <marc_nijdam@hp.com>
399 * Fixed segfault with 'cut -f 1 -d:' and added 'cut -s' suport.
400 Fix thanks to Arne Bernin <arne@matrix.loopback.org>
401 * Several fixes from Marius Groeger <mag@sysgo.de>
402 - Added support for "sh -c command args..."
403 - Fixed globbing, i.e. 'echo * *' and 'echo "******"' now work.
404 - Added shell environment variable substitution
405 - Added the "read" shell builtin.
406 * Fixed cursor editing in cmdedit.c. The following keyboard sequence
407 used to create an infinite loop: ls, cursor up, left, down.
408 * Added support for being a login shell, so things like
409 '-su' or '-sh' (stuff where argv[0][0]=='-') will now always
410 invoke the shell. Now you can use BusyBox as a login shell.
411 * ls.c now ignores '-g', since some ftp clients like that sort
412 of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
413 * Fix to init.c from Stuart Menefy <Stuart.Menefy@st.com> so that
414 it always sets the controlling terminal before running any programs
415 * Several fixes from Matt Kraai <kraai@alumni.carnegiemellon.edu>
416 - Fixed tr so it recognizes standard escape sequences.
417 Merged common escape seq. code from tr and echo into utility.c.
418 - Major work in updating/cleaning up the docs, and getting the
419 new SGML based docs into shape.
421 - BusyBox should now poweroff when asked to do so.
422 - Fixed 'ln -n' and 'ln -s' so they both work properly.
423 * Reorganized signal names in kill.c for better architecture support
424 -- patch thanks to simon wood <simon@mungewell.uklinux.net>
425 * In 0.43, backspace and delete worked properly, but with 0.45,
426 it just echoed a ^? for backspace, and ^H for control-h. This
427 was due to a broken macro in init.c, that is now fixed.
428 * Removed sfdisk from BusyBox. It was buggy, fat, and we really
429 couldn't maintain it very well, so including it was not really
430 very appropriate. Those wanting an fdisk are invited to
431 grab a copy from util-linux.
432 * Added 'dumpkmap' to allow people to dump a binary keymap, which can
433 then be loaded in by 'loadkmap' -- submitted by
434 Arne Bernin <arne@matrix.loopback.org>
435 * Fixed NFS so it supports 2.4.x kernels and NFSv3.
436 * Brand, new versions of grep and sed which use libc regex routines,
437 thanks to Mark Whitley <markw@lineo.com>. The hand-tooled
438 "regexp.[ch]" files have been removed. Much help on these from
442 -Erik Andersen, 11 July 2000
446 * Now compiles vs libc5 (which can save lots of space for
448 * Added BB_FEATURE_TRIVIAL_HELP which compiles out most all of the
449 help messages (i.e --help). Saves 17k over a full compile.
450 * Added cut and tr from minix, since due to the license change,
451 we can now use minix code. Minix tr saves 4k.
452 * insmod now works. It costs 29k, but imagine an initrd with a
453 staticly linked busybox containing only insmod and sh, a few /dev
454 entries, and a kernel module or two... It doesn't get smaller
455 then this folks (I pity the fool that writes insmod in asm ;-).
456 Many kudos go to Ron Alder <alder@lineo.com> for finishing this off!
457 * Added a mini ar archive utility, especially written for BusyBox by
458 Glenn McGrath <bug1@netconnect.com.au>
459 * Added mktemp, contributed by Daniel Jacobowitz <dan@debian.org>
460 * Added setkeycodes, for those that have wierd keyboard buttons.
461 * Added md5sum, uuencode and uudecode -- thanks to Alfred M. Szmidt
462 <ams@trillian.itslinux.org> for contributing these.
463 * Added 'grep -v' option (inverted search) and updated
464 docs accordingly. -beppu
466 * Replaced the telnet implementation with one written by
467 Tomi Ollila <too@iki.fi> It works great and costs 3k.
468 * BusyBox sh (lash) now supports being used as a standalone shell. When
469 BB_FEATURE_SH_STANDALONE_SHELL is defined, all the busybox commands may
470 be invoked as shell internals. Best used when compiling staticly
472 * BusyBox sh (lash) internals now behave as expected wrt pipes
474 * Fixed ping warnings -- fix from Sascha Ziemann <szi@aibon.ping.de>
475 * Fixed update segfault
476 * Fixed mknod -- minor number was always 0
477 * Fixed tar option parsing, so both "tar xvf foo.tar" and
478 "tar -xvf foo.tar" now work (i.e. no "-" before options)
479 (this was very broken in 0.43).
480 * Several contributions from Randolph Chung <tausq@debian.org>.
481 * cp/mv now accepts the -f flag
482 * tail can now accept -<num> commands (e.g. -10) for better
483 compatibility with the standard tail command
484 * added a simple id implementation; doesn't support sup. groups yet
485 * logname used getlogin(3) which uses utmp. Now it doesn't.
486 * whoami used getpwuid(3) which uses libc NSS. Now it behaves.
487 * Add support for "noatime" and "nodiratime" mount flags to mount.
488 * Changed 'umount -f' to mean force, and actually use umount2.
489 * Changed 'umount -l' to mean "Do not free loop device".
490 * Fixed basename to support stripping of suffixes. Patch thanks
491 to xiong jianxin <jxiong@uiuc.edu>
492 * cp -fa now works as expected for symlinks (it didn't before)
493 * zcat now works (wasn't working since option parsing was broken)
494 * Renamed "mnc" to the more correct "nc" (for netcat).
495 * Makefile intelligence updates
496 * Changed the way init parses /etc/inittab entries to avoid problems
497 with commands that contain colons in them. Fix thanks to
498 Pavel Roskin <proski@gnu.org>
499 * Fixed a warning in utility.c due to char being unsigned on Linux/PPC,
500 Fix thanks to Pavel Roskin <proski@gnu.org>
501 * Made "killall" complain (not error and exit) about processes that it
502 cannot find by name -- Pavel Roskin <proski@gnu.org>
503 * Fixed more and ps to have sensible terminal width defaults, thanks
505 * Fixed all fatalError() calls lacking a "\n", thanks to Pavel Roskin.
506 * Fixed a segfault in yes when no args were given -- Pavel Roskin.
507 * Simplified freeramdisk and added argument checking -- Pavel Roskin.
508 * Fixed segfault caused by "touch -c"
509 * Fixed segfault caused by "rm -f"
510 * Fixed segfault caused by "ln -s -s" and similar abuses. Further fixes
511 and "--" support from Pavel Roskin.
512 * Fixed segfault caused by "cp -a -a" and similar abuses.
513 * Implemented "rm -- <foo>". Implementation fixed by Pavel Roskin.
514 * "which" rewritten to use stat(). Fixes to improve its compatability
515 with traditional implementations -- Pavel Roskin.
516 * "mount" now reports errors from nfsmount() and assumes NFS mount
517 if ':' is present in the device name - Pavel Roskin
518 * Fixed exit status for killall - Pavel Roskin
519 * Fixed 'swapon -a' and 'swapoff -a', which were broken.
520 * Fixed 'mount -a' so it works as expected.
521 * Implemented 'ls -R' (enabled by enabling BB_FEATURE_LS_RECURSIVE)
522 * Implemented "ping -s", fixed error messages and argument parsing -
524 * Syslogd will not go to background if "-n" is given. Better help
525 and argument checking -- Pavel Roskin
526 * Fixed a small bug that could cause tar to emit warning messages
527 and not extract the first file in a directory in some cases
528 of nested directories. Thanks to Kevin Traas <kevin@netmaster.com>
529 for helping track this one down.
531 * Fixed grep "Line too long" problem -- John Beppu
532 * Fixed 'grep -q -i B some_file' so it works
533 * math takes input from stdin if no args are given. -- John Beppu
534 * math was renamed to dc. Although it deviates from dc's behaviour,
535 this will probably be remedied in the future. -- John Beppu
538 -Erik Andersen, June 21, 2000
542 Previously, an erronous announcement of BusyBox 0.44 was made, so to
543 avoid possible confusion, we are skipping straight to 0.45, and calling
550 * Major update to the provided documentation.
551 * Busybox now includes a shell! It currently costs 7.5 k (plus an
552 additional 2.5 k if you compile in command line editing). Handles
553 job control, has the usual set of builtins, and does everything
554 except for handling programming statements (if, while, etc...)
555 * Busybox can now work perfectly when /proc is disabled, thereby
556 saving a bunch of memory (kernel /proc support is not thin). This
557 is done by making use of some nice kernel patches I wrote up to
558 support the features that busybox requires and that /proc usually
559 provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
560 patch your kernel with the devps patch in the kernel-patches/
562 * Wrote basename, dirname, killall, and uptime.
563 * tar has been completely rewritten by me. Both tar creation and
564 extraction are now well behaved. Costs 7.6k with all optional
565 tar features enabled, and 5k for just tar extraction support.
566 * Added freeramdisk, which will free up all memory associated
567 with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
568 and then adjusted a bit by me.
569 * Added tr from John Lombardo <john@deltanet.com>
570 * Added echo and test (from me).
571 * Added usleep contributed by Nicolas Pitre <nico@cam.org>
572 * BusyBox's bss size has been majorly reduced (was 384668, is now 28740).
573 * Several fixes from Pavel Roskin <proski@gnu.org>:
574 - When `tail' fails to open a file it now exits.
575 - When `syslogd' is given the `-n' option it should still use
576 fork() for running klogd.
577 * nslookup types are now changed to u_int32_t (instead of uint32_t)
578 changed per a patch from Pascal Bellard <pascal.bellard@ascend.com>
579 * Fixed "du" so it gives the same answers as GNU "du" (busybox du used
580 to count hard-linked files more then once). Many thanks to
581 Friedrich Vedder <fwv@myrtle.lahn.de> for the fix.
582 * Removed /proc dependancies for init and free (while maintaining
583 exactly the same functionality). /proc takes up 90k of kernel
584 space, so it is nice to avoid using it at all costs.
585 * init no longer tries to mount /proc (unless there is less the 1 meg
586 free). Use of /proc (or not) is policy that should be set up in
587 /etc/fstab (or in hardcoded scripts), not in init.
588 * Fixed rebooting when init runs as an initrd.
589 * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
590 - update.c rewritten to look more like update-2.11
591 - moveed the inode hash out of du.c and into utility.c to make
592 it a common resource that can be used by other apps.
593 - cp_mv.c now checks inodes to see if a source and dest are
594 the same, and prints an error (instead of endlessly looping).
595 - mv now attempts to do a rename, and will fall back to doing
596 a copy only if the rename fails.
597 - Syslogd now supports multiple concurrent connections
598 * Several fixes from Pavel Roskin <proski@gnu.org>:
599 - Fixes to sort. Removed "-g", fixed and added "-r"
600 - Fixes to the makefile for handling "strip"
601 * An initial telnet implementation was added by
602 Randolph Chung <tausq@debian.org>.
603 * Fixed a bug where "sed 's/foo/bar/g'" (i.e. a script w/o a "-e")
604 * ps now supports BB_FEATURE_AUTOWIDTH, and can adjust its width
605 to match the terminal (defaults to width=79 when this is off).
606 * ps now accepts (and ignores) all options except for "--help" (which
607 as would be expected displays help).
608 * Fixed mount'ing loop devices when the filesystem type was not
609 specified. It used to revert to non-loop after the first try.
610 * all mallocs now use xmalloc (and so are OOM error safe), and
611 the common error handling saves a few bytes. Thanks to
612 Bob Tinsley <bob@earthrise.demon.co.uk> for the patch.
613 * Fix "+" parsing bug in date, from "Merle F. McClelland" <mfm@cts.com>.
614 * Fix symlink following bug in chmod -R and friends.
615 * Now allows SYSV style 'chown foo:bar' in addition to 'chown foo.bar'
616 * Fixed a bug in the busybox globbing routine such that 'find /dir -name [i]'
625 * Fairly massive restructuring of umount.c to deal with remounting
626 busy devices read-only. Adds a -r option to control that; it is
627 optionally compiled in with BB_FEATURE_REMOUNT
628 * Added a bunch of functions to mtab.c to interact with the
629 {get,set,end}mntent interface; as it turns out, those functions do
630 not appear to be re-entrant, and that causes a lot of problems with
631 the way umount was originally written.
632 * Makes init send TERM and KILL (instead of HUP and KILL) on reboot
633 to be more consistent with sysvinit
634 * Changes to init.c to use the new -r option to umount. Also increased
635 the sleep time between the time the TERM and KILL signals are sent
640 * cp.c, mv.c: removed, replaced by cp_mv.c which has been
641 extensively rewritten from the original cp.c.
642 * Fixed cp and mv so if the source and destination are a the
643 same directory it will print an error and continue.
644 * Also added a warning message to the `mv' usage string saying that
645 this is not GNU mv, and it will break hard links. cp also breaks
647 * ln.c: implemented `-n' switch, no-deref symlinks.
648 * include<sys/param.h>: and use PATH_MAX everywhere. busybox: File
649 * name buffer overrun guards to prevent future crashes.
650 - Always check exit status.
651 - Purge all use of `creat()', replace with `open()'.
653 - recursiveAction was overriding the value of followLinks thus
655 - isDirectory now takes a followLinks boolean, updated all callers
656 - copyFile had the followLinks logic reversed.
657 * messages.c: New file. Put common error message strings all in
658 one place in an attempt to shrink the binary a little.
663 * changed fsck_minix.c to reduce its .bss size significantly
665 * Made tar creation support in busybox tar optional. You no longer
666 * _have_ to put a "-" in front of tar options. Tar could inadvertently
667 * change permissions and ownership on
668 certain directories pointed to by symlinks.
669 * Made grep and grep -h do the right thing wrt printing
670 the file name (it failed to print files names in many cases).
671 * Fix a namespace aliasing problem wereby if du was built in, the
672 symlink for both du and dutmp would be installed, or then rm was
673 built in, the symlinks for both rm and rmmod would be installed.
674 * Added a closelog() to init.c after loging -- fix thanks to
675 Taketoshi Sano <kgh12351@nifty.ne.jp>
676 * Rewrote and simplified logger. Added the "-t" option, and made it
677 behave itself a bit better.
678 * Optional support contributed by Ben Collins <bcollins@debian.org>
679 for the kernel init chroot patch by Werner Almesberger, which
680 allows init to chroot to a new device, and umount the old one.
681 * Fixed bug that wouldn't let one chown a symlink -- it would
682 always dereference before. -beppu
683 * Fixed a bug where init could have reference already freed memory.
684 Found and fixed by Taketoshi Sano <kgh12351@nifty.ne.jp>
685 * Several contributions from Friedrich Vedder <fwv@myrtle.lahn.de>
686 * Added (and documented) "-n" option for head
687 * Cleanup for a number of usage messages -- also
688 contributed Friedrich Vedder <fwv@myrtle.lahn.de>
689 * Cosmetic fix to busybox.c (Don't print a comma at the
690 end of line if there are no more application names).
691 * Fixed a stupid bug in "head" option handling ("head -n"
693 * Moved commonly used functions "xmalloc()" and "exit()"
694 to utility.c (with proper #ifdef's).
695 * Created a tiny tail implementation, removing -c, -q, -v, and making
696 tail -f work only with a single file. This reduced tail from 6k to
697 2.4k. The bigger/more featured tail can still be had by disabling
698 BB_FEATURE_SIMPLE_TAIL in busybox.defs.h
699 * Ping now falls back to doing the right thing if /etc/protocols
701 * Fixed mount and umount. Previously they could leak loop device
702 allocations, causing the system to quickly run out. Fix for umount
703 by Ben Collins <bcollins@debian.org>, and mount was fixed by me.
704 * ls formatting on eight charactor user names fixed by
705 Randolph Chung <tausq@debian.org>.
706 * cp could, when copying symlinks, change permissions of the
707 files pointed to by the symlinks.
708 * Several fixes from Pavel Roskin <proski@gnu.org>:
709 - `chown' with 1 argument displayed the error incorrectly
710 - `fdflush', `length' and `printf' crashed if run without arguments
711 - `fdflush' tried to flush itself using *argv
712 - added "skip" and "seek" to dd.
713 - ls no longer messus up output when combining files and
714 directories on the command line
715 * swapoff -a was not working. Now it is.
716 * init did not cleanly unmount filesystems on reboot. Now it does.
717 * "sed -ne s/foo/bar/" worked but "sed -n -e s/foo/bar/" didn't.
719 * Some architectures (PowerPc) assume chars are unsigned, so they could
720 not distinguish between EOF and '\0xFF' in sed. Sed now uses ints.
721 * Began converting error handling to use some common routines
723 * syslogd now has better message handling and ignores SIGHUP.
724 * install.sh had a bug preventing installation to the specified
725 target directory. Fix from Gilbert Coville <gilbert@mvista.com>
726 * You can now spefify alternative strip commands -- change
727 also from Gilbert Coville.
733 * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
734 by Edward Betts <edward@debian.org>
735 * Fixed a bug in both cp and mv preventing 'cp foo/README bar'
736 type commands (file in a directory to another directory) from
738 * Fixed a logger bug that caused garbage to be written to the syslog
739 (unless you used busybox syslog, which hid the bug). Thanks to
740 Alex Holden <alex@linuxhacker.org> for the fix.
741 * /bin/true and /bin/false were echoing a blank line when run.
743 * mkdir -p would print an error when asked to mkdir an existing dir
744 with no interveining subdirectories.
745 * Fixed "syslogd -O" so that it works. Added -o loop option for mount,
746 * and support in umount for loop
747 devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
748 <bcollins@debian.org>
749 * Several fixes from Marco Pantaleoni <panta@prosa.it> compile in
750 * fullWrite() not only if BB_TAR is defined, but also
751 if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
752 * add some compiler optimizations to further reduce executable size
753 (as a side note, on my machines the largest code is generated
754 by gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with
756 * Compile now won't fail if busybox.def.h defines
757 BB_FEATURE_LINUXRC but not BB_INIT. (init_main used to be
758 referenced, but not compiled)
759 * Fixed a bug in setting TERM for serial console support. TERM now
760 defaults to "ansi" for serial consoles.
761 * Fixed a bug in handling the CONSOLE env. variable for serial
764 -Erik Andersen, Jan 15, 2000
767 * New Apps: sort, uniq. -beppu New Apps: lsmod, rmmod -erik New Apps:
768 * fbset contributed by Randolph Chung <tausq@debian.org>. New App::
769 * loadacm contributed by Peter Novodvorsky <petya@logic.ru>
770 for loading application character maps for Unicode fonts.
771 * Major init re-work. init now supports inittab (slightly different
772 but similar to sysvinit), allowing me to get all the policy out of
773 init and into the conf file. It works just fine without inittab
774 being present, but if you dont like the default behavior you can
775 now do something about it. Init is much cleaner as a result.
776 * Fixed an bug in syslogd causing it to stop after 20 minutes. -erik
777 * Fixed an embarrasing segfault in head -beppu Fixed the embarrasing
778 * failure of 'logger -p'. -erik Added the -s option to du -beppu
779 * Re-worked the source tree a bit so it will compile under glibc 2.0.7
780 with the 2.0.x Linux kernel.
781 * Added 'grep -q' thanks to a patch from "Konstantin Boldyshev"
783 * Grep -i previously failed on UPPER CASE patterns due to a silly
784 regexp implementation bug that is now fixed.
785 * Fixed a bug where tar would set, and then clear SGID and SUID bits.
786 * Fixed a bug where tar would not set the user and group on device
788 * Fixed a bug where tar would not restore the time to files. Fixed a
789 * major security problem with tar -- it changed ownership
790 of any file pointed to by a symlink to 777 (like say libc....)
792 * cp and mv were very broken when moving directories. I have rewritten
793 them so they should now work as expected.
794 * sed now supports addresses (numeric or regexp, with negation) and
795 has an append command, thanks to Marco Pantaleoni <panta@prosa.it>
796 * Fixed dmesg. It wasn't parsing its options (-n or -s) properly.
797 * Some cosmetic fixes to ls output formatting to make it behave more
799 * Fixed a stupid segfault in kill. Several fixes from Friedrich Vedder
800 * <fwv@myrtle.lahn.de>:
801 - Added gunzip -t, removed gunzip.c dead code,
802 - fixed several typos
803 - Glibc 2.0.7 and libc5 compile fixes
804 * Fixed a bug where 'mknod --help' would segfault.
807 -Erik Andersen, Jan 07, 2000
810 * New Apps: ping, hostname, and mkfifo contributed by Randolph Chung
811 <tausq@debian.org>. 3 items off the TODO list!
812 * I wrote free (just calls "cat /proc/meminfo"). Added tail, based on
813 * tail from GNU textutils-1.19, but adjusted
814 to suit my evil purposes. Costs 6k. I'll make it smaller
816 * on reboot, init called 'umount -a -n', which caused errors
817 when BB_MTAB was not enabled. Changed to 'umount -a', which does
819 * init will now try to run /sbin/getty if it is present (for easy
820 integration with the about-to-be-released tinylogin.)
821 * kill now behaves itself properly, added 'kill -l' to list signals 'ls
822 * -l' was failing on long directories, since my_getid was leaking
823 one file descriptor per file. Oops.
824 * Fixed rebooting from init. I'd accidently left some debugging code
826 which blocked reboots.
827 * Fixed reboot, halt (and added poweroff) such that they handle it when
828 init is not at PID 1 (like when running in an initrd).
829 * Added a prelinary du implementation. Some parameter parsing
830 stuff still needs to be added. -beppu (John Beppu
832 * Implemented tee. -beppu Implemented head. -beppu
834 -Erik Andersen, Dec 10, 1999
837 * Fixed a segfault in 'umount -a' when a badly formed /etc/fstab
839 * df will not exit on error, but will stat all mounted filesystems.
840 * Fixed tar so uid/gid/permissions on extracted tarballs will be
842 * Fixed find -name so it properly uses shell wildcard patterns
843 (i.e. `*', `?', and `[]') instead of regular expressions, which
844 was causing some confusing and unexpected behavior.
845 * Added klogd to syslogd, so now the log will contain both system and
847 * syslogd now creates the /dev/log socket to make sure it is there, and
848 is actually a socket with the right permissions.
849 * I've taken a first step to making busybox not need the /proc
850 filesystem. Most apps don't need it. Those that _require_ it,
851 will complain if you enable them when you disable
852 BB_FEATURE_USE_PROCFS.
854 -Erik Andersen, Dec 5, 1999
857 * Wrote a micro syslogd, and a logger util (to log things to the syslog
858 from the command line or scripts) With both compiled in, costs 4k.
859 * Fixed 'make install' so symlinks are installed in their proper
860 * locations. Changed the build system slightly so that features can
862 or disabled from the busybox.defs.h header file, without trying to
863 compile in a source file named after that featue (unless that file
865 * Several options are now moved into busybox.defs.h Now 'rm -R' and 'rm
866 * -r' both work. dd now properly handles input beyond 1 block from
867 * stdin. Fixed a bug where tar unpacked everything a directories.
869 from createPath into mkdir where it belonged, thereby making tar
871 * Fixed an off-by-one bug in cat. Given a list of file it wouldn't cat
873 last file in the list.
874 * Fixed 'ls -ln' so numeric group/uid are presented properly, and fixed
876 so when uid/gid is not in /etc/{passwd,group} the numeric group/uid
877 are presented properly.
881 -Erik Andersen, Nov 25, 1999
884 * fixed dd so it properly defaults to stdin and stdout when no
885 if= and of= are set (fix thanks to Eric Delaunay).
886 * Don't try to close the file descriptor of a pipein tar. (fix also
889 * Made createPath be quiet (again thanks to Eric Delaunay). If
890 * BB_CONSOLE_CMD_IF_RC_SCRIPT_EXITS is defined, then whatever
891 command you define it as will be run if the init script exits.
892 * Updated install.sh to make it more robust (thanks to Adam Di Carlo)
893 * NFS support added to mount by Eric Delaunay. It costs 10k when
895 in, but that is still a big win for those that use NFS.
896 * Made 'rm -f' be silent for non-existant files (thanks to Eric
897 * Delaunay). changed zcat.c to gunzip.c. It now obeys the principle
899 and acts as god intended gunzip and zcat to act. They answer
900 --help and obey the '-c' flag.
901 * Fixed a bug in mv which caused it to not move files when the
904 * Fixed a decimal-instead-of-octal bug causing mkdir to make
906 with very wrong permissions.
907 * chmod would overwrite file permissions instead of modifying them.
908 Now it properly modifies permissions.
909 * Init now sends warnings destined for the console to /dev/console to
911 they show up on whatever the active console it. Otherwise
912 important messages (for example that the system is rebooting) were
913 not seen when switched to a different VT.
915 -Erik Andersen, Nov 17, 1999
918 * gzip now obeys the principle of least surprise and acts like god
920 (i.e. it accepts a file name, answers --help, and obeys the '-c'
921 flag and only then outputs to stdout).
922 * Fixed more.c to compile autowidth on sparc and set initial winsize
923 to 0,0 in case the TIOCGWINSZ ioctl fails. Fix thanks to Eric
925 * Fixed tar so it now works as expected (it had TRUE/FALSE backwards)
926 * tar now accepts --help chmod, chown, and chgrp usage now works
927 * General usage (i.e. --help) cleanups for most apps umount now parses
928 * options correctly tar can now unpack tarballs containing device
930 sockets, and fifos (though it can't pack them up) thanks to Matt
931 Porter. Creating archives containing these is still left to the
933 * fixed up the license in more.c to properly point to Bruce Perens.
935 -Erik Andersen, Nov 11, 1999
938 * ls -l now displays link names outside the current directory,
939 Patch thanks to Eric Delaunay
940 * init now properly handles sparc serial consoles and does a
941 better job of finding the real console device rather than using
942 /dev/console which doesn't support job control. Patch also thanks
944 * more started to read from stdin after the last file was finished, and
945 options were not parsed correctly (fix thanks to Eric Delaunay).
946 * more will now use the terminal size if BB_FEATURE_AUTOWIDTH is on.
947 * rm wouldn't remove a symlink unless the symlink was valid. This was
948 a side effect of the busybox 0.32 recursiveAction() fix. Things
949 should now work correctly.
950 * grep wouldn't grep stdin. Now it does. sed wouldn't sed stdin. Now
951 * it does. sed was appending a \n to the end of lines with
953 Now it doesn't do that.
954 * ls -l now bypasses libc6 nss when displaying user/group names.
955 Now uses my_getpwuid and my_getgrgid.
957 -Erik Andersen, Nov 8, 1999
960 * Fixed a bug where init could hang instead of rebooting.
961 * Removed some debugging noise from init.c
962 * Fixed ln so it works now (it was very broken).
963 * Fixed df so it won't segfault when there is no /etc/fstab,
964 * If BB_MTAB is not defined, df and mount will whine if /etc/fstab
965 is not installed (since they cannot fixup "/dev/root" to
966 state the real root device name)
967 * merged some redundant code from mtab.c/df.c into utility.c
969 -Erik Andersen, Nov 5, 1999
972 * More changes -- many thanks to Lineo for paying me to work on
973 busybox. If you have any problems please let me know ASAP at
974 andersen@lineo.com or andersee@debian.org
975 * usage() now prints the BusyBox version. This will help folks
976 realize that they are not in Kansas anymore.
977 * Fixed mkdir -m option so that it works. kill segfaulted w/o any
978 * arguments. Now it doesn't do that. kill wasn't properly accepting
979 * signal names. It does now. Added new apps chvt and deallocvt (I
980 * should probably add open) Major rewrite of init.c. Code is now
981 * readable by mere mortals IMHO. Wrote sed -- weighs only 1.8k (5.8k
982 * with full regular expressions!). Fixed a stupid seg-fault in sync
983 * Fixed mount -- mount -a failed to parse and apply mount options Fixed
984 * umount -n (patch thanks to Matthew Grant <grantma@anathoth.gen.nz>)
985 * umount -a no longer umounts /proc Added BB_MTAB, allowing (at the
986 * cost of ~1.5k and the need for a rw /etc)
987 folks to use a real /etc/mtab file instead of a symlink to
988 /proc/mounts. mount, and umount will add/remove entries and df
989 will now use /etc/mtab if BB_MTAB is defined.
990 * Fixed a nice bug in recursiveAction() which caused it to infinitely
991 hunt through /proc/../fd/* creating new file descriptors if it
992 followed the /dev/fd link over to /proc. recursiveAction() now
993 lstat's the file when followLinks==FALSE so it won't follow links
994 as the name suggests. Fix thanks to Matt Porter
998 -Erik Andersen, Nov 4, 1999
1001 * I added a changelog for version 0.30. adjusted find internals to
1002 * make it smaller, and removed
1004 * Fixed a segfault in ps when /etc/passwd or /etc/group
1005 are absent. Now will warn you and carry on.
1006 * Added in optional _real_ regular expression support (to be
1007 the basis for a future sed utility). When compiled in it adds
1008 3.9k, but makes grep much more capable.
1009 * Checked out using nftw(3) for recursive stuff, but unfortunatly
1010 it wasn't supported before GNU libc 2.1, and some folks use glibc
1011 2.0.7 since it is much smaller than that latest and greatest.

1016 Major changes -- lots of stuff rewritten. Many thanks to Lineo for
1017 paying me to make these updates. If you have any problems with busybox,
1018 or notice any bugs -- please let me know so I can fix it. These
1022 * busybox can now invoke apps in two ways: via symlinks to the
1023 busybox binary, and as 'busybox [function] [arguments]...'
1024 * When invoked as busybox, the list of currently compiled in
1025 functions is printed out (no this is not bloat -- the list has
1026 to be there anyway to map invocation name to function).
1027 * busybox no longer parses command lines for apps or displays their
1028 usage info. Each app gets to handle (or not handle) this for
1030 * Eliminated monadic, dyadic, descend, block_device, and
1031 postprocess. It was cumbersome to have so many programs
1032 cobbled together in this way. Without them, the app is much
1034 * All shared code now lives in utility.c, and is properly
1035 ifdef'ed to be only included for those apps requiring it.
1036 * Eliminated struct FileInfo (the basis of monadic, dyadic, etc)
1037 so now each app has the function prototype of (da-dum): extern
1038 int foo_main(int argc, char** argv); which speeds integration
1040 * Adjusted the Makefile to make it easier to
1041 {en|dis}able debugging.
1042 * Changed default compiler optimization to -Os
1043 (optimize for smaller binaries).
1046 * To cope with the new app function prototype and the removal of
1047 monadic, dyadic, etc, the following apps were re-written:
1048 * cat - Works same as always. chgrp, chmod, chown -
1049 * rewrite. Combined into a single
1050 source file. Absorbed patches from Enrique Zanardi
1051 <ezanard@debian.org> that removes the dependency on
1052 libc6 libnss* libraries.
1053 * cp - Can now do 'cp -a' can can copy devices,
1054 pipes, symlinks, as well as recursive or non-recursive
1056 * fdflush - adjusted to remove dependancy on struct
1057 * FileInfo. find - Now includes some basic regexp matching
1058 which will be the basic of a future mini-sed.
1059 * ln - Same functionality. mkdir - Added -p flag to
1060 * feature set. mv - rewrite. rm - Added -f flag to
1061 * feature set. rmdir - Same functionality. swapon,
1062 * swapoff - Combined into a single binary. No longer
1063 uses /etc/swaps. swap{on|off} -a uses /etc/fstab
1065 * touch - Same functionality. date - adjusted with a patch
1066 * from Matthew Grant <grantma@anathoth.gen.nz>
1067 to accomodate glibc timezone support. I then ripped out GNU
1069 * mkswap -- new version merged from util-linux. Can now make
1071 * Replaced the old and star, unstar, and tarcat with the tar
1072 implementation from sash. Now tar behaves as god intended it
1073 to (i.e. tar -xvf <file> and tar -cf <file> <dir> work).
1074 * dd -- rewritten. Can with with files, stdin, stdout. Added the
1075 * following new apps: loadfont -- added from debian boot floppies
1076 * chroot -- added based on a patch from Paolo Molaro
1077 * <lupus@lettere.unipd.it> grep -- I just wrote it. Only matches
1078 * simple strings ps -- I just wrote it. Has _no_ options at all,
1079 * but works. fsck_minix, mkfs_minix -- added from util-linux, but
1081 internationalization and such to make them smaller.
1082 * sfdisk -- Added from util-linux (minus
1083 * internationalization and such). Probably some other
1084 * changes that I forgot to document...

1089 This version was a messy pre-alpha. stay away or it will bite you.
1090 -Erik Andersen, Sep 24, 1999
1093 mini-netcat (mnc) rewritten.
1096 Mount now supports -a, and -t auto.
1097 Mount now updates mtab correctly for 'ro'.
1098 More checks screen rows size, outputs bytes percentage.
1099 Printf added as module.
1101 Touch now creates files. -c option for no create.
