I'm getting sorrier by the moment I helped flame this idiotic thread, but:

But this solution uses two processes if echo is not a shell builtin!
Better do it with one (and add a / where you forgot):
$ FILE=/bin/hello
$ sed 's#/[^/]*$##' << END
$FILE
END
/bin
By the way, obviously all these solutions (sed, rev, and the shorter expr
solution) fail to replicate one property of dirname: dirname of a slash-less
path should return a ".".
For people still not fed up with this thread, here's an even simpler (and
more correct in case of no slash) solution in zsh:
$ FILE=/usr/bin/hello
$ echo ${FILE:h}
/usr/bin
$ FILE=aaa
$ echo ${FILE:h}
.
(I indented the whole paragraph above by one space, because who knows what
kind of havoc a single dot on a line in an email would cause...)
