Your mileage may vary.

$ time perl -le print+time

real 0m0.002s

$ time date +%s

real 0m0.001s

(Those results were surprisingly consistent on my Linux box.)

My version of "keep it simple" in this situation is that if you have to invoke another language interpreter to provide a required feature, the base script itself should probably be written in a different language.

If the base script will remain a shell script, you're better off invoking smaller, less-expensive programs whenever possible. This cost savings diminishes very quickly if your script has to make a lot of external program calls, where with a more fully featured language you might have handled all those external functions in-line.

If it matters enough, of course, you try both, and profile the results to see which is more efficient under load.

I'm probably preaching to the choir on this, and for that I apologize. It's already been a long week.
