Eric Andersenb287e2e2003-08-08 23:40:12 +0000[diff] [blame]40 Tha 'ash' shell adds about 60k in the default configuration and is
41 the most complete and most pedantically correct shell included with
42 busybox. This shell is actually a derivitive the Debian 'dash' shell
43 (by Herbert Xu), which was created by porting the 'ash' shell
44 (written by Kenneth Almquist) from NetBSD.

Eric Andersenb287e2e2003-08-08 23:40:12 +0000[diff] [blame]117 lash is the very smallest shell (adds just 10k) and it is quite
118 usable as a command prompt, but it is not suitable for any but the
119 most trivial scripting (such as an initrd that calls insmod a few
120 times) since it does not understand any Bourne shell grammer. It
121 does handle pipes, redirects, and job control though. Adding in
122 command editing makes it a very nice lightweight command prompt.

Eric Andersenb287e2e2003-08-08 23:40:12 +0000[diff] [blame]129 The minix shell (adds just 30k) is quite complete and handles things
130 like for/do/done, case/esac and all the things you expect a Bourne
131 shell to do. It is not always pedantically correct about Bourne
132 shell grammer (try running the shell testscript "tests/sh.testcases"
133 on it and compare vs bash) but for most things it works quite well.
134 It also uses only vfork, so it can be used on uClinux systems.
