Sometimes you want to ssh to a machine, leave a process running there and exit. Screen allows you to do that:

$ screen
$ sh myscript.sh
[type Ctrl+a+d to detach window]
$ exit

The process won’t stop even if you close the ssh session.

First upload your public key to the server you want to log in:

scp .ssh/id_rsa.pub user@1.2.3.4:/home/user

On the server, add the public key file to the authorized_keys file:

cat id_rsa.pub >> .ssh/authorized_keys

Now you can login using public key authentication and you don’t have to enter a password anymore.
