The command shell situation is a big mess. We have three or four different
shells that don't really share any code, and the "standalone shell" doesn't
work all that well (especially not in a chroot environment), due to apps not

init
General cleanup (should use ENABLE_FEATURE_INIT_SYSLOG and ENABLE_FEATURE_INIT_DEBUG).
depmod
busybox lacks a way to update module deps when running from firmware without the
use of the depmod.pl (perl is to bloated for most embedded setups) and or orig

- Unify base64 handling.
- There's base64 encoding and decoding going on in:
- networking/wget.c:base64enc()
- coreutils/uudecode.c:read_base64()
- coreutils/uuencode.c:tbl_base64[]
- networking/httpd.c:decodeBase64()
- And probably elsewhere. That needs to be unified into libbb functions.
Do a SUSv3 audit
Look at the full Single Unix Specification version 3 (available online at

This one's open to everybody, but I'll wind up doing it...

- Makefile stuff:
- make -j is broken, -j1 is forced atm
+Bernhard Fischer <busybox@busybox.net> suggests to look at these:
New debug options:
-Wlarger-than-127
+ Cleanup any big users
+ -Wunused-parameter
+ Facilitate applet PROTOTYPES to provide means for having applets that
+ do a) not take any arguments b) need only one of argc or argv c) need
+ both argc and argv. All of these three options should go for the most
+ feature complete denominator.

- unify itoa: netstat.c, hush.c, lash.c, msh.c

Move __get_hz() to a better place and (re)use it in route.c, ash.c, msh.c
