I auto start gnu screen when I ssh into one on my own servers. When I am done, I have to d to detach. Then exit to quit ssh. This means that when I ssh into the server again at some point in time, I can continue where I left off.
Can I create a alias (for instance) that will (from within screen) detach and drop ssh?
Starting screen when logging in on the remote host (executed on your local machine):
ssh -t user@host screen
In the screen session, on the remote host, to detach and log out (which would end the SSH session unless you are using a persistent connection using a control socket (i.e. using the ControlMaster setting with ControlPersist in ~/.ssh/config)):
screen -d
Later, to log in and re-attach:
ssh -t user@host screen -r
Note that you have to use -t with ssh, forcing pseudo-terminal allocation, to start screen in this way.
The alias on the remote host would be for screen -d, maybe detach='screen -d' or something similar.
On the local host, you could have a section in your ~/.ssh/config file saying
Host *-screen
RequestTTY force
RemoteCommand screen -d -R
Host myhost myhost-screen
HostName myhost.somedomain.example.com
User myname
Then, whenever you use
ssh myhost-screen
a screen session would be created (or re-attached to) on the specified host, while
ssh myhost
would not use screen.
Note: RemoteCommand was added in OpenSSH 7.6 (2017-10-03).
For tmux:
tmux new-session -A -s "%n" in ~/.ssh/config instead of screen -d -R.tmux detach-client or tmux detach to detach.Collected from the Internet
