Pushd and popd commands

I feel stupid for only finding those today. After years in the terminal.

pushd saves the current directory on a stack, changes to a specified directory. Then popd changes back to the top directory and pops it.

pushd /var/log    # Now in /var/log, stack contains /home
pushd /etc        # Now in /etc, stack contains /var/log, /home
popd              # Returns to /var/log
popd              # Returns to /home

I love those for aliases with agents or for executing build scripts.

Major downside is they are very noisy, so you always got to > /dev/null.
