I used Common Lisp from the mid 1980s until about 5 years ago when my customers wanted Clojure, if they wanted Lisp development done. I have never seriously used CL as a scripting language but for a while I was using Gambit-C Scheme for small compiled apps and command line tools. Gambit-C is very good for this purpose.

BTW, Clojure is "out" for command line tools because of the JVM startup time but I have thought about Clojurescript + node.

There is also scsh (scheme shell - http://scsh.net/) although not being maintained anymore.

There's a plan to do some work on it (including trying to port it to 64 bit) this summer.

An updated version by Roderic Morris can be installed as a library atop the latest version of Scheme 48. It's on github: https://github.com/scheme/scsh

I think it's 64-bit (?). Most of the time it hasn't mattered for me, at least when writing scripts.

You can also just build the "old" version (0.6.7) with the `-m32` GCC flag, and it works fine on 64-bit Linux and OS X. It's very stable in my experience, and works fine.
