Here’s a nifty SSH ’shortcut’. This requires that you have an existing SSH key on the remote box.
Use this script, named ssh-to:
#!/bin/sh ssh `basename $0` $*
Add to the bin directory, then add symlinks to your remote box(es):
$cd /bin $ln -s ssh-to remote-server-name
Issue a remote command:
remote-server-name free
