Simple sysadmin tools - Screen on CentOS

<p>Screen is one of my favourite utilities when managing servers - it allows you to use multiple shell windows from a single SSH session and to keep these active even after logging out. It is super useful for monitoring long-running processes.</p>

Installing Screen on CentOS

[ ~]$: yum install screen

Creating a new screen

[ ~]$: screen

Detaching from an active screen

Ctrl-A D

Force detaching from another session

[ ~]$: screen -d

Listing all screens

[ ~]$: screen -ls

Re-attaching to a screen

[ ~]$: screen -ls


There is a screen on:
	2257.pts-0.myServer	(Detached)
1 Socket in /var/run/screen/S-my_root.

[ ~]: screen -r 2257

Exiting a screen

[ ~]$: exit
