Last change on this file since 821 was 821, checked in by Bruno Cornec, 18 years ago

Addition of busybox 1.2.1 as a mindi-busybox new package
This should avoid delivering binary files in mindi not built there (Fedora and Debian are quite serious about that)

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

170 hush is a very small shell (just 18k) and it has fairly complete
171 Bourne shell grammar. It even handles all the normal flow control
172 options such as if/then/elif/else/fi, for/in/do/done, while loops,
173 etc.
174
175 It does not handle case/esac, select, function, here documents ( <<

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

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

222 depends on CONFIG_MSH || CONFIG_LASH || CONFIG_HUSH || CONFIG_ASH
223 help
224 This option causes the selected busybox shell to use busybox applets
225 in preference to executables in the PATH whenever possible. For
226 example, entering the command 'ifconfig' into the shell would cause
227 busybox to use the ifconfig busybox applet. Specifying the fully
228 qualified executable name, such as '/sbin/ifconfig' will still
229 execute the /sbin/ifconfig executable on the filesystem. This option
230 is generally used when creating a statically linked version of busybox
231 for use as a rescue shell, in the event that you screw up your system.
232
233 Note that this will *also* cause applets to take precedence
234 over shell builtins of the same name. So turning this on will
235 eliminate any performance gained by turning on the builtin "echo"
236 and "test" commands in ash.
237
238 Note that when using this option, the shell will attempt to directly
239 run '/bin/busybox'. If you do not have the busybox binary sitting in
240 that exact location with that exact name, this option will not work at
241 all.
