Last change on this file since 6be9a4d9 was 6be9a4d9, checked in by Thorsten Glaser <tg@…>, 19 years ago

let the user decide which of the available shells he
wants as /bin/sh - not only these included with busybox

(ash and mksh are probably the only ones which will
work, but like this I won't affect any existing con-
figuration)

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

141 hush is a very small shell (just 18k) and it has fairly complete
142 Bourne shell grammar. It even handles all the normal flow control
143 options such as if/then/elif/else/fi, for/in/do/done, while loops,
144 etc.
145
146 It does not handle case/esac, select, function, here documents ( <<
147 word ), arithmetic expansion, aliases, brace expansion, tilde
148 expansion, &> and >& redirection of stdout+stderr, etc.

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

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

194 help
195 This option causes the selected busybox shell to use busybox applets
196 in preference to executables in the PATH whenever possible. For
197 example, entering the command 'ifconfig' into the shell would cause
198 busybox to use the ifconfig busybox applet. Specifying the fully
199 qualified executable name, such as '/sbin/ifconfig' will still
200 execute the /sbin/ifconfig executable on the filesystem. This option
201 is generally used when creating a statically linked version of busybox
202 for use as a rescue shell, in the event that you screw up your system.
203
204 Note that when using this option, the shell will attempt to directly
205 run '/bin/busybox'. If you do not have the busybox binary sitting in
206 that exact location with that exact name, this option will not work at
207 all.
