It provides minimalist replacements for most of the utilities 17you usually find in fileutils, shellutils, findutils, textutils, grep, gzip, 18tar, etc. BusyBox provides a fairly complete POSIX environment for any small 19or embedded system. The utilities in BusyBox generally have fewer options than 20their full-featured GNU cousins; however, the options that are included provide 21the expected functionality and behave very much like their GNU counterparts. 22 23BusyBox has been written with size-optimization and limited resources in mind. 24It is also extremely modular so you can easily include or exclude commands (or 25features) at compile time. This makes it easy to customize your embedded 26systems. To create a working system, just add a kernel, a shell (such as ash), 27and an editor (such as elvis-tiny or ae). 28 29=head1 USAGE 30 31When you create a link to BusyBox for the function you wish to use, when BusyBox 32is called using that link it will behave as if the command itself has been invoked. 33 34For example, entering 35 36 ln -s ./BusyBox ls 37 ./ls 38 39will cause BusyBox to behave as 'ls' (if the 'ls' command has been compiled 40into BusyBox). 41 42You can also invoke BusyBox by issuing the command as an argument on the 43command line. For example, entering 44 45 ./BusyBox ls 46 47will also cause BusyBox to behave as 'ls'. 48 49=head1 COMMON OPTIONS 50 51Most BusyBox commands support the B<-h> option to provide a 52terse runtime description of their behavior. 53 54=head1 COMMANDS 55 56Currently defined functions include: 57 58adjtimex, ar, basename, busybox, cat, chgrp, chmod, chown, chroot, chvt, clear, 59cmp, cp, cpio, cut, date, dc, dd, deallocvt, df, dirname, dmesg, dos2unix, dpkg, 60dpkg-deb, du, dumpkmap, dutmp, echo, expr, false, fbset, fdflush, find, free, 61freeramdisk, fsck.minix, getopt, grep, gunzip, gzip, halt, head, hostid, 62hostname, id, ifconfig, init, insmod, kill, killall, klogd, length, ln, 63loadacm, loadfont, loadkmap, logger, logname, ls, lsmod, makedevs, md5sum, 64mkdir, mkfifo, mkfs.minix, mknod, mkswap, mktemp, more, mount, mt, mv, nc, 65nslookup, ping, pivot_root, poweroff, printf, ps, pwd, rdate, readlink, reboot, 66renice, reset, rm, rmdir, rmmod, route, rpm2cpio, rpmunpack, sed, setkeycodes, 67sh, sleep, sort, stty, swapoff, swapon, sync, syslogd, tail, tar, tee, telnet, 68test, tftp, touch, tr, true, tty, umount, uname, uniq, unix2dos, update, uptime, 69usleep, uudecode, uuencode, watchdog, wc, wget, which, whoami, xargs, yes, zcat, 70[ 71 72=over 4 73 74
