konsole killing child processes on exit, and midnight commander...
Scenario 1:
I am in a konsole bash session. I run this command:
...and then in that window I run midnight commander with
...then open an mp3 file in vlc, and then go back to the mc window and hit control-c, midnight commander exits, and then I "exit" the konsole window and the vlc process continues to run, as desired.
Scenario 2:
I am in a konsole bash sesion and enter:
...and then use mc to open an mp3 file with vlc. Then when I ctrl-c in midnight commander, both the konsole window and vlc die.
Why is running the command in konsole with -e causing its child processes to die when it dies, but opening it without -e and running a child process does not cause this? I notice that in scenario 1, if instead of typing "exit" I instead alt-f4 and kill the window, then it does kill vlc, just like in scenario 2. From this I deduce that when you ctrl-c a process in a "konsole -e" session, it sends SIGHUP or SIGKILL or whatever to all child processes.
The reason I'm struggling with this is that I want to call up mc with a keyboard shortcut, be able to spawn child processes (like vlc playing a file) and the ctrl-c the mc window and have the vlc survive, but I can't figure out how to make it work.
Any idea of how I can tell konsole that the -e process should live on as a background process? Or any other way around this? I tried going into the menu of mc and doing exit that way (rather than ctrl-c) but it had the same result.
