I've been using the bash shell for so long that I'm not sure about my csh syntax, but I think this should work: First, put the new commands someplace conventional in your path, like /usr/local/bin. I think in csh type shells (such as tcsh) you need to type rehash now. Now you can just type the commands with no path. The alias you can define this way: alias cdf "cd `posd`" where those are backticks around the posd. That should be one way to do it.

Backticks alone will not work because they will be evaluated when the alias is defined, not in the current context of the shell. You can see this by looking at the output from alias cdf. It will say "cd somedirectory".

You need to use the eval command, like this:

alias cdf 'cd "`eval posd`"'

Right- I should have used single quotes, which does work (I just tested it in csh):

alias cdf 'cd `posd`'
