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