== Screen program ==

With screen you can create one or more sessions in your current SSH terminal. Just run

{{{
screen
}}}

Ctrl a c - Creates a new screen session so that you can use more than one screen session at once.

Ctrl a n - Switches to the next screen session (if you use more than one).

Ctrl a p - Switches to the previous screen session (if you use more than one).

Ctrl a d - Detaches a screen session (without killing the processes in it - they continue).

To close a screen session where all tasks are finished you can type
{{{
exit
}}}

Back on your normal SSH terminal, you can run
{{{
screen -ls
}}}
to get a list of your current screen sessions.

To reconnect to one of these sessions, run
{{{
screen -r 1234.my.server
}}}
