lash [\s-1FILE\s0]...
or: sh \fB\-c\fR command [args]...
.Sp
lash: The BusyBox LAme SHell (command interpreter)
.Sp
This command does not yet have proper documentation.
.Sp
Use lash just as you would use any other shell.  It properly handles pipes,
redirects, job control, can be used as the shell for scripts, and has a
sufficient set of builtins to do what is needed.  It does not (yet) support
Bourne Shell syntax.  If you need things like \*(L"if\-then\-else\*(R", \*(L"while\*(R", and such
use ash or bash.  If you just need a very simple and extremely small shell,
this will do the job.
