Execute command in another terminal and closing it without killing command

Question

For closing terminal without killing script/command we use & operator at last while calling command. Like:

gedit &

_{Here I used gedit as an example command}

Same thing I want to do on another terminal (from current terminal). I am using following command(s) to run script/command onto another terminal:

• gnome-terminal -e 'gedit'
• gnome-terminal -x bash -c 'gedit'

But here if I close new opened terminal, then script/program runnung by [command] also killed. So I've tried using & as follows:

• gnome-terminal -e 'gedit' &
• gnome-terminal -x bash -c 'gedit' &

But none of above is working.

So, How can I achieve this : From current gnome-terminal, Execute command in another gnome-terminal and close that (new-opened) terminal after launching command without killing running command.

Answer 1

You can use nohup command - it disconnects the process from the terminal, so even if you close the gnome-terminal window, it will continue to run.

Example: gnome-terminal -e "nohup bash gedit"

You can user screen utility. Screen is a full-screen window manager that multiplexes a physical terminal between several processes (typically interactive shells - for more details execute man screen.

As soon as you execute the screen command in the shell a new window with a shell in it will be created. You can execute whatever command/script/daemon you want. You can easily detach from the window using the key shortcut: Ctrl+A+D.

To list all sessions you have started you can use screen -list. You can attach to the lastly detached session using screen -r or if you want to attach on a particular session use screen -r <host.tty>.

Example:

[root@dns-ldap ~]# screen -list
There are screens on:
        5708.pts-0.dns-ldap     (Detached)
        5648.pts-0.dns-ldap     (Detached)
        5725.pts-0.dns-ldap     (Detached)
3 Sockets in /var/run/screen/S-root.

[root@dns-ldap ~]# screen -r 5708.pts-0.dns-ldap #this will attach you to terminal 5708.pts-0.dns-lda. I have detached from the terminal usinc Ctrl+A+D
[detached]
[root@dns-ldap ~]# screen -r 5648.pts-0.dns-ldap
[detached]
[root@dns-ldap ~]#

Combining nohup & screen, Al last I achieved what I want.

By kirill-a, the command : gnome-terminal -e "nohup bash gedit" is suggested.

However by using above command, I can run command and can close new opened gnome-terminal without killing running command, BUT I've to manually close new opened gnome-terminal window. And I want it to be closed automatically after launching command.

By Dimitar Dimitrov screen command is suggested.

At-last I used screen with nohup and my Final command becomes:

• gnome-terminal -e 'screen nohup gedit'

• gnome-terminal -x bash -c 'screen nohup gedit'

By using either of above command(s) I get: command launched in new terminal window and after launching command, new opened terminal closed without killing running command.
