sash and msh shells

I'd like to run a not completely initialization script in a µCLinux system. I can run the "sash" and/or the "msh" shell (sash is the default, msh can be enabled via busybox).



I need to do some "if" clauses.



Does sash and/or msh provide "if" ? What can be used as decisions ? (e.g. directory exist, results of commands, ...) What is the syntax ?


I need to use some variables.



I do know that both can do variables, but sash does not have "export". Are all variables exported by sash, or does it export none ?



I suppose both can do "source" ("." command) to let me set variables from a file.



Can somebody point me to descriptions of sash and msh ?



Thanks,


-Michael

Google is over this way ---> try "sash shell" or "stand alone shell"

Yep,

I did find the sash man page in a Linux installation.

But I did not find anything about conditional execution. Is it true that sash can't do any "if" ?

Moreover I did not find out if sash exports all it's variables into the environment of the processes it starts.

I did not find any description of msh, that I heard is recommended if you want to do things sash can't.

From the description, 'sash' is something that is usually only used when nothing else will run (ie. system is scrogged).
