See free space with:
|
||
|
|
|
||
|
|
> free
|
||
|
|
|
||
|
|
and make it human readable with:
|
||
|
|
|
||
|
|
> free -h
|
||
|
|
|
||
|
|
Or `-m` for megabytes.

# Proccesses
|
||
|
|
|
||
|
|
See running items in current terminal with
|
||
|
|
|
||
|
|
> ps
|
||
|
|
|
||
|
|
or more with
|
||
|
|
|
||
|
|
> ps -a
|
||
|
|
|
||
|
|
Or the entire system with
|
||
|
|
|
||
|
|
> ps -e
|
||
|
|
|
||
|
|
Or the entire system with more information, BSD style, with:
|
||
|
|
|
||
|
|
> ps aux
|
||
|
|
|
||
|
|
And then search for a particular program with
|
||
|
|
|
||
|
|
> ps aux | grep cmus
|
||
|
|
|
||
|
|
# Jobs
|
||
|
|
|
||
|
|
Pause a job with ^z. Put it in the background with the '&' suffix.
|
||
|
|
|
||
|
|
List jobs in the current shell with
|
||
|
|
|
||
|
|
> jobs
|
||
|
|
|
||
|
|
And then you can pull number 1 up again with
|
||
|
|
|
||
|
|
> fg 1
|
||
|
|
|
||
|
|
Or continue running a stopped job with:
|
||
|
|
|
||
|
|
> bg 1
|
||
|
|
|
||
|

# Nice
|
||
|
|
|
||
|
|
This changes how nice a program is, from -20 (horrid) 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
|

|
