* Add in a shell tagline (per lash/hush behavior) to make it easierEric Andersen2001-07-072-31/+158
| | | | | | to know which shell is in use. Add in 'help' to list available builtins, and fixup msh so it can do STANDALONE_SHELL. -Erik

* Some updates to ash from vodz. Makes ash smaller. I made a fewEric Andersen2001-07-021-2671/+2788
| | | | | changes, esp describing all the current ash configuration options. Now ash adds 66k in the default configuration.

* This is a busybox port of the Minix shell. It is reasonably capable,Eric Andersen2001-06-291-0/+4799
| | | | | | | | | | handles all the basic stuff (for, case/esac, while, if/then/else), and is very small (adds just 38k on x86). It is not as rigorously correct about Bourne semantics as bash, but for most things it is quite workable. There is still some work to be done to further shrink it (it has its own globbing functions instead of using the libc ones, for example), but it is quite usable as is. -Erik

* This a an ash applet I put together. It is similar to the one putEric Andersen2001-06-281-0/+14242
| | | | | | | together by vodz, but uses newer sources, has the removed features commented out instead of simply deleted (so they could be re-enabled) and the builtins all work. This adds 72k. -Erik

* Some more cleanups. Of special importance, never free a pipeEric Andersen2001-06-221-27/+52

* Another hush update from Larry:Eric Andersen2001-06-071-14/+16
| | | | | | | Fixes the interaction between if/then/else/fi syntax and variables. I planned to do it right from the beginning, but my implementation was buggy. Also adds the relevant test cases. Also adds some old Matt Kraai variable test cases that got left out somehow.

| | | | | | signal handling in cmdedit.c. Disabling it makes the shells behave themselves again. hush isn't quite there, but is getting close... -Erik

* This patch covers one big part of variable handling.Eric Andersen2001-05-151-5/+49
| | | | | | | | | | | | | | | $ a=b foo should be handled correctly. $ a=b is parsed OK, but the actual variable setting is not yet written. Except for some weird exceptions related to quoting rules, this code passes (matches ash behavior) all the tests I threw at it. If someone now writes set_local_var(), and updates lookup_param() to match, we can claim success! - Larry
