## Screen

If you're connected to your server via ssh we highly recommend you to execute all long running commands in screen. The reason for this, is that all running processes can be interrupted if the connection with the server is dropped while not using screen.

### Usage

To start a screen session just type:

    screen

Your ssh client's title should change to [screen X: bash]root@yourhostname:

And there you can type your long running command (for example the download of an ISO image, making a dump of your DB or restoring it).

Then you can detach from the screen session by pressing CTRL+a followed by d. You'll return to your shell:

At this time all your executed commands are running in the background within the screen session and you can close your ssh client and get back to the session at any time by reaatching to the screen.

If you have only one screen session running then you can reattach to it by typing:

    screen -r

If you have several screen sessions then you have to find out the ID of the screen you want to reattach to and specify it:

For more information please read the manual page of the command:

    man screen
