I think an OOPish DSL as a shell is pretty wrong[0], to be honest. Most of the time in UNIX what you're doing is chaining commands or automating. So perhaps what's needed is a DSL with a more functional, stream-based approach. Something along the lines of:

> map `rm -rf ` (grep "*.tex" (ls))

[0]: I haven't had much experience with FOOP, however.
