- The `ps` command is an effective way to see the running processes on a Linux system.
- The output of the ps will show the following:
- `PID`: the process ID
- `TTY`: Terminal type used by the user
- `Time`: Amount of CPU time used by the process (NOT the time this process has been running for)
- `CMD`: The command or executable running
# Commands
```bash
# View all running processes
ps -A
# View process tree
ps axjf
# show process for all users (a)
# display the user that launched the process (u)
# show processes that are not attached to a terminal (x)
ps aux
```
