Shells:
|
||||
|
||||
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 Bourne shell grammer. It does handle pipes, redirects, and
|
||||
job control though. Adding in command editing makes it a very nice
|
||||
lightweight command prompt.
|
||||
|
||||
hush is also quite small (just 18k) and it has very complete Bourne shell
|
||||
grammer. It handles if/then/else/fi just fine, but doesn't handle loops
|
||||
like for/do/done or case/esac and such. It also currently has a problem
|
||||
with job control. Using hush is not yet recommended.
|
||||
|
||||
msh: 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 grammer (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 was only recently added, so there is still
|
||||
room to shrink it further...
|
||||
|
||||
ash: This adds about 60k in the default configuration and is the most
|
||||
complete and most pedantically correct shell included with busybox. This
|
||||
shell was also recently added, and several people (mainly Vladimir and Erik)
|
||||
have been working on it. There are a number of configurable things at the
|
||||
top of ash.c as well, so check those out if you want to tweak things.
