I'm back to running longer jobs as part of my research. If I run a task overnight, I want to conserve energy and not keep it running after I finish. I suppose this would also apply to cloud billing, you want it to do the job and then stop.

This technique will require you to have sudo privileges on the machine.
|
||
|
|
|
||
|
|
1. Change user to root.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo su
|
||
|
|
```
|
||
|
|
|
||
|
|
2. Run job as regular user, write output to file, and then poweroff.
|
||
|
|
|
||
|
|
```bash
|
||
|
|
su -u user task > output.txt && chown user:user output.txt && poweroff
|
||
|
|
```
