I want to run a command foo on one terminal and pass the result to another terminal. Is it possible to do this ?

4Also look into tmux and screen, both of which allow you to take over, mirror, or just execute commands on, other sessions.– KevinJul 12, 2014 at 18:32

Yes, it is. A picture worth a thousand words:
So, you have to redirect the output of your command using > operator to /dev/pts/#. You can find # using who or w command. If tou want to redirect and the errors, use:
<command> >& /dev/pts/#

5You will need probably a script to do that: the script will take as argument your command then should open a new
gnome-terminaland detect the tty (usingttycommand) of the new terminal and finally send the output to it. Jul 12, 2014 at 17:25
Something like this for your $HOME/.bashrc :
ng() { gnome-terminal -x sh -c "$*; bash"; }
This will run a command and shows the result on a new terminal window.
Examples:
ng ls -l
ng echo foo
Edit: To consider aliases from the $HOME/.bashrc use this instead:
ng() { gnome-terminal -x bash -ic "$*; bash"; }
then the output of ls should be colored (thanks to Radu Rădeanu for this hint).

4You will understand if you will run
type lsand thenng type ls:) Jul 12, 2014 at 18:01 -
1if write function in one line in bashrc, maybe need a semicolon to end it, or you will meet an "unexpected end of file" error. so
ng() { gnome-terminal -x sh -c "$*; bash" ;}should be better. And if you are using xfce(xfce4-terminal as default emulator):ng() { xfce4-terminal -x sh -c "$*; bash" ;}or you can simply run by any default emulatorng() { x-terminal-emulator -x sh -c "$*; bash";}– user305925Jul 16, 2014 at 1:28
