I have a script, called bin/script, which looks like: echo $0:t Doing 'csh -f bin/script' yields: 'bin/script:t' Doing 'tcsh -f bin/script' (correctly) yields: 'script' Csh clearly doesn't do the Right Thing, but why? (tcsh is version 5.18) Martin -- Uhm... Martin Gemmel

You will need to assign $0 to another variable and then use :t on that new variable. --- Ray Wallace (INTERNET,UUCP) wallace@oldtmr.enet.dec.com (UUCP) ...!decwrl!oldtmr.enet!wallace (INTERNET) wallace%oldtmr.enet@decwrl.dec.com ---

If you want the hundreds of dinky csh bugs like this to go away, plus lots of nice extensions, then use tcsh (FTP from tesla.ee.cornell.edu). -- - Matt Day, Sanyo Icon R&D, mday@icon.com

You should be able to use the modifiers on any variable -- it is a stupid bug. Under the csh, variable modifiers do not work on environment variables either; this bug is also fixed in the tcsh. -- - Matt Day, Sanyo Icon R&D, mday@icon.com

This is a bug, and an obnoxioius one at that. (Since $0 tends to inculde a full path from the sematics of '#!', and so tends to be the positional parameter you are *most* likely to want to ':t'.
