help
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.

Enable 64-bit math support in the ash shell. This will make
the shell slightly larger, but will allow computation with very
large numbers.

Enable support for the ash 'command' builtin, which allows
you to run the specified command with the specified arguments,
even when there is an ash builtin command with the same name.

bool " Enable pseudorandom generator and variable $RANDOM"
default n
depends on BUSYBOX_CONFIG_ASH
help
Enable pseudorandom generator and dynamic variable "$RANDOM".
Each read of "$RANDOM" will generate a new pseudorandom value.
You can reset the generator by using a specified start value.
After "unset RANDOM" then generator will switch off and this
variable will no longer have special treatment.
config BUSYBOX_CONFIG_HUSH
bool "hush"
default n
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.
config BUSYBOX_CONFIG_LASH
bool "lash"
default n
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
bool "msh"
default n
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.

bool "Standalone shell"
default n
depends on BUSYBOX_CONFIG_MSH || BUSYBOX_CONFIG_LASH || BUSYBOX_CONFIG_HUSH || BUSYBOX_CONFIG_ASH
help
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.
