Hmm. You're right. echo $0 works at a shell prompt, but not within a script. I tried it within a script, sort of, by sourcing it. For example, . my_script and it seems to work that way, but not when the script is invoked by name as a command. So far, ls -Al /proc/$$/exe seems to be the best suggestion, but then of course you'll have to parse the output. When I'm writing scripts, I try to use the "least common denominator" approach. In other words, I use code that works with any shell if I can. If I really need to make use of a feature that only works in one particular shell (usually bash), I just force bash to be used by the special comment in line 1: #!/bin/bash And then I know it will always be run by bash, regardless of which shell is the default on the system. -- .''`.
