% cd /home/httpd/perl
% mv rel old && mv beta rel && stop && sleep 3 && restart && err
Let me explain what this does.
Firstly, note that I put all the commands on one line, separated by &&, and only then press the Enter key. As I am working remotely, this ensures that if I suddenly lose my connection (sadly this happens sometimes) I won't leave the server down if only the stop command squeezed in. && also ensures that if any command fails, the rest won't be executed.
