how can I strip the filename from a path in tcsh?

Question

Given this variable in tcsh:

set i = ~/foo/bar.c

how can I get just the directory part of $i?

~/foo

Answer 1

If your system provides a 'dirname' command you could:

set i = `dirname ~/foo/bar.c`
echo $i

Note the missing $ in front of the variable name. This solution is shell agnostic though.
