I love when this 'thing' do stuff while I'm doing something else. We discussed, corrected plan, or it is in the middle of investigation, anyway, it's 5+ minutes. And I want to close the lid of the laptop, but continue this thing to work.
The modern systemd allows me that. This simple script prevent laptop to go to sleep by timeout or by closed lid, as long as it's running. Press Ctrl-C to terminate.
systemd-inhibit --what=handle-lid-switch:idle --who='manual' --why='nosleep script' sleep infinity
Bingo, you can close lid and have stuff continue to be done.
