What processes are currently running in Linux?
If you want to find out what processes are currently running, you can use pidof. For example, pidof xmms will return something like t4l@laptop:~$ pidof xmms 9962 9031
What group are we in?
To quickly check what group our user is in, we can use the id command. To compress the result in a more easily read output, we can use id -Gn. For example: t4l@laptop:~$ id -Gn t4l adm dialout cdrom floppy audio dip video plugdev lpadmin scanner admin
What’s Your’s Is Your’s
In Linux, if you want to see what files from your /home folder belong to your user account, you can launch the ls -alFG $HOME command.
