What kind of test environment do you plan to use rname from? Not trying to suggest that you shouldn't package it, but I wanted to call attention to a little-known feature of the bash exec builtin: ~$ (exec sh -c 'echo $0') sh ~$ (exec -a differentname sh -c 'echo $0') differentname That unfortunately doesn't work in portable sh, though; rname seems like an appropriate option if you can more easily require rname than requiring bash (or a better scripting/testing language). - Josh Triplett
