Tha 'ash' shell adds about 60k in the default configuration and is
|
|
the most complete and most pedantically correct shell included with
|
|
busybox. This shell is actually a derivative of the Debian 'dash'
|
|
shell (by Herbert Xu), which was created by porting the 'ash' shell
|
|
(written by Kenneth Almquist) from NetBSD.

help
|
|
hush is a very small shell (just 18k) and it has fairly complete
|
|
Bourne shell grammar. It even handles all the normal flow control
|
|
options such as if/then/elif/else/fi, for/in/do/done, while loops,
|
|
etc.
|
|
|
|
It does not handle case/esac, select, function, here documents ( <<
|
|
word ), arithmetic expansion, aliases, brace expansion, tilde
|
|
expansion, &> and >& redirection of stdout+stderr, etc.

help
|
|
lash is the very smallest shell (adds just 10k) and it is quite
|
|
usable as a command prompt, but it is not suitable for any but the
|
|
most trivial scripting (such as an initrd that calls insmod a few
|
|
times) since it does not understand any Bourne shell grammar. It
|
|
does handle pipes, redirects, and job control though. Adding in
|
|
command editing makes it a very nice lightweight command prompt.

config BUSYBOX_CONFIG_MSH

help
|
|
The minix shell (adds just 30k) is quite complete and handles things
|
|
like for/do/done, case/esac and all the things you expect a Bourne
|
|
shell to do. It is not always pedantically correct about Bourne
|
|
shell grammar (try running the shell testscript "tests/sh.testcases"
|
|
on it and compare vs bash) but for most things it works quite well.
|
|
It also uses only vfork, so it can be used on uClinux systems.

|
This option causes the selected busybox shell to use busybox applets
|
|
in preference to executables in the PATH whenever possible. For
|
|
example, entering the command 'ifconfig' into the shell would cause
|
|
busybox to use the ifconfig busybox applet. Specifying the fully
|
|
qualified executable name, such as '/sbin/ifconfig' will still
|
|
execute the /sbin/ifconfig executable on the filesystem. This option
|
|
is generally used when creating a staticly linked version of busybox
|
|
for use as a rescue shell, in the event that you screw up your system.
|
|
|
|
Note that when using this option, the shell will attempt to directly
|
|
run '/bin/busybox'. If you do not have the busybox binary sitting in
|
|
that exact location with that exact name, this option will not work at
|
|
all.
