Linux: Background process linked to terminal window

Question

I am running linux and I am running a script/program in the background using

cmd &

This works fine on Solaris, but on my Linux box (2.6.9-55/ Red Hat), the background process stops when the originating terminal window is closed/loses connection. What do I need to change this, so that this works as it works on Solaris?

Answer 1

You have to use the disown command (it may be specific to bash, not sure about it).

Example:

cmd & disown 

should do the trick.

If you want to reattach later the job to the terminal, use:

disown -h 

Alternatively, you can use screen. Use it this way:

screen cmd 

Then, to go back to the terminal, hit ctrl+a, then d.

To come back to the screen, type in any terminal:

screen -r 

Answer 2

if you run nohup cmd &, so the program will ignore the SIGHUP it gets when the termial closes.
