Old 10-19-2012
You need a laptop/O/S that does not reboot when you open the lid, just de-hibernates or un-sleeps. My laptops are co owned or too close to diskless to add an Ubuntu boot to see what the power saving support is. Hibernate is a complete copy of RAM to disk so no power is consumed, but the boot has to reinstate the old images and restart job dispatching. Sleep is a low power state where little or no i/o takes place, but RAM is intact under power and the restart is really fast.

Commands 'jobs', 'bg', 'fg' are only good on the parent, launching, interactive ksh/bash (sh?) shell. Batch need not apply. You cannot, to my knowledge, adopt processes of other terminals or none.

Yes.. For that only you have to use nohup command.. Just use nohup followed by filename. The process will be paused in the process table while the system is off.

Nohup just shrugs off the sighup, no other magic is provided.
