cl-rashell VS clesh

The library Rashell is helpful to define interfaces to external commands, especially to define functions which vary along the following dimensions:

I have written Rashell a Common Lisp (SBCL) library which makes it easy to interface with Unix tools in general and core POSIX utilities in particular.

Congratulations for sharing your work! While the focus is very different you can find another kind of replacement for the “find” command (actually a Lisp interface) in [Rashell](https://github.com/michipili/cl-rashell/blob/master/src/posix.lisp#L129). Maybe it is interesting to you (e.g, comparison purposes) so I am sharing this here again.

Now, it's only personal, but I like to fire one-off shell commands… can we escape the Lisp REPL or not? If not, we could use a shell pass-through, for example "! ls" with clesh. Ruricolist's cmd is nice to have too. This is becoming an heresy, but what if we could fire a shell command and interpret its result with a Lisp function, or mix and match the two? Lish is doing an awesome work already, although it's a difficult field. Interactive commands like sudo and htop work there, at least. It ships a Lisp REPL and a debugger for the terminal too (similar to Roswell, then).

Clesh - extends Common Lisp to embed shell code in a manner similar to perl's backtick. (I read awesome-cl) It could ease the process to include external calls.
