how can I run a command via ssh that will not be terminated while pressing Control+C

[Apollo]

I am trying to run a shell script or command via ssh terminal and need to be able to prevent it from being terminated via the Control+C key.

Under GUI shell, I can have the following:

trap '' sigint && gstat

however if I run it under ssh, then I get the following message:
trap: Command not found

With tmux.

I was actually running the script in tmux but got messed-up with the shortcut key and I pressed Ctrl+C key.
It killed the script within tmux.

I hate when I do that.. and I do that too often. :(

You can also do this with '&' to run the command in the background and 'nohup' to detach the command from the current session so it doesn't die if you logout.

As in: nohup command &

You'll need to redirect the output of the command to a file so you can actually monitor what the command is up to. It's easier to just run tmux and be careful with your keys.

I'll try this one later, but it would be more practical and more user friendly if the primary key binding of tmux were always displayed as a tab menu or something, rather than guessing.

You could always use screen. Start your command, then detach your screen. Come back later and reattach the screen.

Start: screen
Detach: Ctrl+a then d
Reattach: screen -r

tmux is a newer, better screen.

Start: tmux
Detach: Ctrl+b then d
Reattach: tux attach

You can even change the control character to 'a' so it matches screen. (I always used 'n' on both)

The problem with tmux is that there is now help available unless you type Ctrl+b. That day I was confused and pressed the Ctrl+C and this cause the command within tmux to be canceled.

I don't think there's any solution for PEBKAC errors.

This is why the following becomes handy:

Code:

trap '' sigint && gstat

but this doesn't work over ssh as the "trap " command is not found.
