I really like seeing more people use Lisp, and it's neat to see what other people come up with, but I'll stick with Emacs, Slime and occasionally eshell. More often than not it's easiest to just use the Common Lisp functions for creating directories and interacting with the system, but when that doesn't work, I have a function similar to this one in my .sbclrc file: (defun run (cmd) (with-output-to-string (outs) (uiop:run-program cmd :output outs))) At work, I've even created a small Common Lisp library for calling our JSON APIs over HTTPS and running commands on our test clusters using SSH. It's all tightly integrated into Emacs, and I can use it do things like open remote files in my local Emacs.
