Can you use screen? Something like - vi /path/to/the/shell/script.sh #!/bin/bash /usr/bin/screen -dmS myScreenSessionName /path/to/command/to/start/in/Session.sh and then call it via SSH - /usr/bin/ssh -l username servername /path/to/that/shell/script.sh & Then when you connect to the server later, you can do a `screen -r myScreenSessionName` Chris

I thought about screen, but the manual says NAME screen - screen manager with VT100/ANSI terminal emu- lation I thought it was something else, a display manager for Xorg.

Use tmux. check out "byobu" which is an easy to use wrapper around tmux/screen. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I agree with using tmux, but no script is necessary. After starting a tmux session, detach from the session, <ctrl-b><d> to reattach the session from anywhere, ssh to the machine where the session resides and tmux new -t <session-name> I use tmux constantly to access a session attached (ssh) to four machines, email and a few log displays, constantly from anywhere using cygwin on a usb stick for windows or ssh from linux. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535 @ http://linuxcounter.net -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I tried byobu, but I find it confusing. Too much information on those status lines that I do not need.

to reattach the session from anywhere, ssh to the machine where the session resides and tmux new -t <session-name>
tmux seems simple enough. ssh machine tmux .... work <ctrl-b><d> to detach. exit ssh ssh machine tmux attach and you are back in. Interestingly, I can attach two xterms to the same tmux session. I guess I could use this for supporting someone remotely, on the same xterm, one local, one remote, so that they see what I type. My only problem is remembering NOT to use ctrl-d to exit ssh, it kills the tmux session. - -- Cheers, Carlos E. R.

Does the repeat-connection needs to be with ssh? Within an ssh session, typing "~<C-z>" (that's the key with an tilde ~, and Ctrl-Z following) suspends the ssh session. One has an active shell back at the command issuing server then.[*] With the command "fg" one can resume the ssh session.

Mmm... I didn't say that the client machine usually hibernates between sessions. The idea is to ssh-in, start something in an xterm with ssh, when needed hibernate or poweroff (the client side), and take again the same terminal hours or even days later.

Interesting! Not of use for me this time, I think, but interesting. I'll write all this in my notes, so that I remember next time. However, the choice of "~" is awkward in a Spanish keyboard: to type it I need "[Alt-gr][4]" (alt-gr is the right hand "Alt" key), so the entire combo becames more complicated.
[*] If one has several cascadet ssh sessions, it's an "interesting" game to guess the amount of tildes before <Ctrl-Z> that one needs to get at an intermediate ssh session.
Indeed...! I always wondered how to do that if needed. I never had to, but it is interesting to know.

Then it doesn't help; you'll need to use something like screen.

Same here in Germany, it's [Alt-gr][+] on German keyboards.

Ever wondered why typing a ~ at the start of a line isn't output immediately? It's an ssh escape character. To see the possible options, type "~?" at the start of a line. Very important is also "~." to terminate a session if it hangs remotely and doesn't accept Ctrl-C, Ctrl-Z, or such.
