Basic screen command usage and examples
|
||
============================================================
|
||
|
||
|
||
|
||
|
||
Screen is a very useful command that offers the ability to use multiple shell windows (sessions) from a single SSH session. When the session is detached or there is a network disruption, the process that is started in a screen session will still run and you can re-attach to the screen session at any time. This also comes in handy if you want to run a long process persistently or connect to shell sessions from multiple locations.
|
||
|
||
In this article, we will show the basics of installing and using screen on a Linux VPS.
|
||
|
||
### How to install screen
|
||
|
||
Screen comes preinstalled on some of the popular distributions. You can check if it is installed on your server using the following command
|
||
|
||
```
|
||
screen -v
|
||
Screen version 4.00.03 (FAU)
|
||
```
|
||
|
||
If you do not have screen to the VPS, you can easily install it using the package manager provided by the OS.
|
||
|
||
### [CentOS][4]/RedHat/Fedora
|
||
|
||
```
|
||
yum -y install screen
|
||
```
|
||
|
||
### [Ubuntu][5]/[Debian][6]
|
||
|
||
```
|
||
apt-get -y install screen
|
||
```
|
||
|
||
### How to start a screen session
|
||
|
||
You can start screen by typing ‘screen’ at the command prompt and a new screen session will be started which looks the same as the command prompt
|
||
|
||
```
|
||
screen
|
||
```
|
||
|
||
It is a good practice to start screen sessions with descriptive names so you can easily remember which process is running in the session. To create a new session with a session name run the following command
|
||
|
||
```
|
||
screen -S name
|
||
```
|
||
|
||
and replace ‘name’ with a meaningful name for your session.
|
||
|
||
### Detach from screen session
|
||
|
||
To detach from the current screen session you can press ‘Ctrl-A‘ and ‘d‘ on your keyboard. All screen sessions will still be active and you can re-attach to them at any time later.
|
||
|
||
### Reattach to screen session
|
||
|
||
If you have detached from a session or your connection is interrupted for some reason, you can easily re-attach by executing the following command:
|
||
|
||
```
|
||
screen -r
|
||
```
|
||
|
||
If you have multiple screen sessions you can list them with ‘ls’
|
||
|
||
```
|
||
screen -ls
|
||
|
||
There are screens on:
|
||
7880.session (Detached)
|
||
7934.session2 (Detached)
|
||
7907.session1 (Detached)
|
||
3 Sockets in /var/run/screen/S-root.
|
||
```
|
||
|
||
In our example, we have three active screen sessions. So, if you want to restore the session ‘session2’ you can execute
|
||
|
||
```
|
||
screen -r 7934
|
||
```
|
||
|
||
or you can use the screen name
|
||
|
||
```
|
||
screen -r -S session2
|
||
```
|
||
|
||
### Terminate screen session
|
||
|
||
There are several ways to terminate the screen session. You can do it by pressing ‘Ctrl‘ + ‘d‘ on your keyboard or use the ‘exit’ command line command.
|
||
|
||
To see all useful features of the screen command you can check screen’s man page.
|
||
|
||
```
|
||
man screen
|
||
|
||
NAME

||
