 # busybox
 BusyBox? v0.60.3 (2002.12.19-12:19+0000) multi-call binary

 Usage: busybox [function] [arguments]...
   or: [function] [arguments]...

        BusyBox? is a multi-call binary that combines many common Unix
        utilities into a single executable.  Most people will create a
        link to busybox for each function they wish to use, and BusyBox?
        will act like whatever it was invoked as.

 Currently defined functions:
        [, ash, basename, busybox, cat, chgrp, chmod, chown, chroot, cp,
        cut, date, dd, df, dirname, dmesg, du, echo, env, expr, false,
        free, grep, gunzip, gzip, halt, head, id, ifconfig, init, insmod,
        kill, killall, klogd, linuxrc, ln, logger, ls, lsmod, mkdir, mkfifo,
        mknod, mkswap, modprobe, more, mount, mv, pidof, ps, pwd, reboot,
        reset, rm, rmdir, rmmod, route, sed, sh, sleep, sort, stty, swapoff,
        swapon, sync, syslogd, tail, tar, test, touch, tr, true, umount,
        uname, uniq, uptime, wc, which, whoami, xargs, yes, zcat
