This page has information about the commands and features desired for a busybox replacement program.

See Busybox replacement project for the project proposal for this work.

Command List

[Rob - can you massage this list?]

The first release of a busybox replacement should include the following commands: [insert candidate list here]

Toybox currently implements

The triaged toybox is currently implementing usable versions of:

 bzcat cal cat catv chroot chvt cksum count cp df dirname dmesg
 echo false help link mkswap nc netcat nice nohup oneit patch pwd
 rmdir seq setsid sha1sum sleep sort sync tee true truncate tty
 uname unlink unshare wc which yes

And minimal versions of:

 mdev sh

See the Toybox todo list for the most up to date status.

Toolbox commands

Toolbox in Android (what version?) implements the following commands:

date id uptime schedtop ifconfig start newfs_msdos
ls route netstat ioctl reboot getprop cmp insmod chmod
r cat lsmod chown log df top printenv ionice setprop rmmod setconsole
sleep watchprops notify wipe smd iftop rmdir dd vmstat hd rm mount
ln lsof getevent ps dmesg renice kill mkdir sendevent nandread mv
sync stop umount

The following are unique to Android:

 alarm schedtop newfs_msdos getprop log setprop watchprops notify wipe
 iftop getevent sendevent nandread stop smd setconsole

Ones I'm not sure about:

  • r?
  • ioctl?

Random Notes

Can implement incrementally

Rob wrote:

One nice thing about busybox/toybox/toolbox is you can install multiple implementations side by side, and have what symlinks you create (or what comes first in the $PATH) determine who is implementing what.

This allows gradual transitions. Each release, we replace a couple more commands from the old one, until the old one finally isn't being used for anything anymore and we can uninstall it...
