Shell internals/implementation

[Shamim Zvonko Mohamed]

I'm looking for implementation details of any of the popular shells (Bourne,
C, Korn) - papers, books, anything like that. Ideally something that describes
the internals at the C code level, but everything is welcome...

Please email.

Thanks - s
