Without getting into the "why are you using X to do the job": I've got a csh script in an arbitrary location. But I need to know from within the script where it exists in the directory structure. The reason for that is I need to source a file from within that same directory (where the script is). If I look for cwd or pwd, I get the directory my shell was when when I ran the script, not where the script itself is located.
As an additional condition, I can't use anything on the local system, as the script will be run over NFS to various systems (hence one of the reasons it's arbitrary). And it has to be csh, no tcshisms. -Mark
