[ILUG] useful tip...

[kevin lyda]

let's say you're in dir /usr/lib and you cd to /etc/httpd.  you do whatever
you need to do there and then want to go back to /usr/lib.  instead of
typing

    cd /usr/lib

just type

    cd -

that will bring you back to the last dir you were in.  those of you
familiar with popd/pushd in tcsh and bash will recognise this as a
poor man's popd (it only maintains a single entry stack).

as an aside this might be confusing for vms users who are used to

    set directory [-]

which is the same as
    
    cd ..

in unix.  but vms is dead, so who cares?  :)
