See running items in current terminal with

or more with

```
2020-01-02 00:04:35 +00:00
Or the entire system with
```bash
ps -e
```
2020-01-02 00:04:35 +00:00
Or the entire system with more information, BSD style, with:

# Jobs
Pause a job with ^z. Put it in the background with the '&' suffix.
List jobs in the current shell with
```bash
jobs
```
2020-01-02 00:04:35 +00:00
And then you can pull number 1 up again with
```bash
fg 1
```
2020-01-02 00:04:35 +00:00
Or continue running a stopped job with:
```bash

# Nice

This changes how nice a program is, from -20 to 19.
2020-01-02 00:04:35 +00:00
Install a program, but nicely, at nice value '10':
```bash
nice -10 sudo apt -y install libreoffice
```
2020-01-02 00:04:35 +00:00
Aggressively use Steam, with a nice value of '-13'.
```bash
nice --13 steam&
```
2020-01-02 00:04:35 +00:00
Find out that Steam's fucking everything up, so you change its nice value with 'renice':
```bash
renice --5 -p 3781
```
2020-01-02 00:04:35 +00:00
Nerf all of roach-1's processes:
```bash
renice 10 -u roach-1
```
2020-01-02 00:04:35 +00:00
... or the entire group
```bash
renice -14 -g hackers
```
