Yes, in my mind this is the way to go (the other alternative, probably unviable, being scsh https://github.com/scheme/scsh). I recently made a decision not to write any bash scripts that include a conditional or loop; for all those use cases python+sh is the way to go. The reason: http://mywiki.wooledge.org/BashPitfalls I can't think of any environment where python would not be available. You can even ship sh.py as a single-file dependency along with your script, so `import cp from sh` will work as expected.

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.
