Under Linux I use 'nohup' which lets a command ignore hangup signals
(which are emitted by the shell on logout), and redirect all terminal
output into a file (which I delete after the job has completed).

(b)ash:

  nohup mdrun [options] >output.log  2>&1 &

(t)csh:

  nohup mdrun [options] >& output.log &
