# The `screen` command
|
||
|
|
|
||
|
|
`screen` - With screen you can start a screen session and then open any number of windows (virtual terminals) inside that session.
|
||
|
|
Processes running in Screen will continue to run when their window is not visible even if you get disconnected. This is very
|
||
|
|
handy for running long during session such as bash scripts that run very long.
|
||
|
|
|
||
|
|
To start a screen session you type `screen`, this will open a new screen session with a virtual terminal open.
|
||
|
|
|
||

## Restore a Linux Screen
|
||
|
|
|
||
|
|
To restore to a screen session you type `screen -r`, if you have more than one open screen session you have to add the
|
||
|
|
session id to the command to connect to the right session.
|
||
|
|
|
||
|
|
## Listing all open screen sessions
|
||
|
|
|
||
|
|
To find the session ID you can list the current running screen sessions with:
|
||
|
|
|
||
|
|
`screen -ls`
|
||
|
|
|
||
|
|
There are screens on:
|
||
|
|
```
|
||
|
|
18787.pts-0.your-server (Detached)
|
||
|
|
15454.pts-0.your-server (Detached)
|
||
|
|
2 Sockets in /run/screens/S-yourserver.
|
||
|
|
```
|
||
|
|
|
||
|
|
If you want to restore screen 18787.pts-0, then type the following command:
|
||
|
|
|
||
|
|
`screen -r 18787`
