40 | help |
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. |

168 | select TEST |
169 | help |
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 ( << |
176 | word ), arithmetic expansion, aliases, brace expansion, tilde |
177 | expansion, &> and >& redirection of stdout+stderr, etc. |
178 | |

180 | config LASH |
181 | bool "lash" |
182 | default n |
183 | select TRUE |
184 | select FALSE |
185 | select TEST |
186 | help |
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. |
193 | |
194 | |
195 | config MSH |
196 | bool "msh" |
197 | default n |
198 | select TRUE |
199 | select FALSE |
200 | select TEST |
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. |

212 | config FEATURE_SH_EXTRA_QUIET |
213 | bool "Hide message on interactive shell startup" |
214 | default n |
215 | depends on MSH || LASH || HUSH || ASH |
216 | help |
217 | Remove the busybox introduction when starting a shell. |
218 | |
219 | config FEATURE_SH_STANDALONE_SHELL |
220 | bool "Standalone shell" |
221 | default n |
222 | depends on MSH || LASH || HUSH || 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. |

244 | bool "Command line editing" |
245 | default n |
246 | depends on MSH || LASH || HUSH || ASH |

254 | help |
255 | Enable vi-style line editing in the shell. This mode can be |
256 | turned on and off with "set -o vi" and "set +o vi". |

288 | bool "Fancy shell prompts" |
289 | default n |
290 | depends on FEATURE_COMMAND_EDITING |
291 | help |

293 | \$ and also using escape codes. |
