Hi,
for starting and running a script on a headless system for me "nohup"
works perfectly.
For interactive session via ssh screen/tmux turned out to be the
solution to detach from jobs started from the commandline.
Both are hints/help I received from the community here. :)
Thank you very much !!! :)))
Since the screen/tmux thingie is THAT convenient I would like to start
this as the default when logging in via ssh.
I could write a script which is started by the shell (zsh) which in
turn is started as part of the login process.
Screen would start another shell and TADA!...
But this is an embedded system...
The result should be a running screen session right after login via
ssh.
Is there any "shorter path" to what I am trying to do -- without the
cascade of shells which do nothing but waiting of the child process to
end?
Thank you very much in advance for any help! Have a nice Sunday!
Best regards,
mcc

you can auto-start a program of your choice directly from an ssh
command. for example:
$ ssh -t myhost screen -R -d
will connect over ssh and then run screen to auto detach then reattach a
running a screen or start a new one if not.
you can of course name your screens so you can connect to
mycompilewindow or mycleverideasvimwindow
alternatively, and if you tend to use a mobile device for ssh you can
but something like in your .bashrc
if [ -n "$SSH_CLIENT" ] || [ -n "$SSH_TTY" ]; then
screen -R -d
fi
which would check to see if ssh variables are set by openssh i.e. it is
an ssh session and then run screen for you

I dont wanted to experiment (and fail)...there were chances to get no
access to the system anymore...
THX!

I have this in ~/.zshrc.
if [[ "${TERM}" != "screen" ]] && [[ -z "${STY}" ]] && [[ ! -f ~/.noscreen ]]; then
screen -xRR && exit
fi

Hi Neil,
this logs me out instantly....
If executed directly from the commandline it works.
Is there any other settings, which may effect screen?
...there is no .screenrc...

Not that I'm aware of, but it "just works"[tm] for me.
I don't have a .screenrc either and /etc/screenrc is standard apart from
changing the command key and caption bar.
Check what $TERM is set to both in and out of screen. Whenver this has
not worked as exected in the past it has been because of changes to
environment variables.
