# Jobs
|
|
|
|
|

Pause a job with ^z. Put it in the background with the '&' suffix.
|
|
|
|
|
|
|
|
|
|
List jobs in the current shell with
|
|
|
|
|

|
|
|
|
|
|

This changes how nice a program is, from -20 to 19.
|

|
|
|
|
|
|
|
|
Install a program, but nicely, at nice value '10':
|
|
|
|
|
|
|
|
|
|
> nice -10 sudo apt -y install libreoffice
|
|
|
|
|
|
|
|
|
|
Aggressively use Steam, with a nice value of '-13'.
|
|
|
|
|
|
|
|
|
|
> nice --13 steam&
|
|
|
|
|
|
|
|
|
|
Find out that Steam's fucking everything up, so you change its nice value with 'renice':
|
|
|
|
|
|
|
|
|
|
> renice --5 -p 3781
|
|
|
|
|
|
|
|
|
|
Nerf all of roach-1's processes:
|
|
|
|
|
|
|
|
|
|
> renice 10 -u roach-1
|
|
|
|
|
|
|
|
|
|
... or the entire group
|
|
|
|
|
|
|
|
|
|
> renice -14 -g hackers
|
|
|
|
|
|
