How to open multi terminal on Ubuntu server?

I have installed Ubuntu 12.04 LTS server .

How can i run more than .sh file in the same time (opening more than terminal)

I can use it on desktop version but i use server version.

Is it possible? if yes how can do?

By default Ubuntu has 7 ttys, on Server they are all command line (desktop the 7th is for X use) You can switch between then using Ctrl + Alt + F1 to Ctrl + Alt + F7

This would allow you run your script in 7 different sessions.

You can also background processes by starting them as normal, but appending an & to the end e.g.

yourscript.sh &

If your script does not terminate itself you will need to locate the pid and kill it (https://unix.stackexchange.com/questions/104821/how-to-stop-a-background-process for more detail on killing)

Use screen. It's perfectly when you need multiple terminals. Specially when you are connected via ssh and you don't want to start another session.

You can, for example, run a command in it, detach, go to another machine, reattach and everything is still there.

Another similar application that provides the same is tmux.

Linux will process one process at a shell at a time, which means script running in your scenario.

At a same time if you need to do some other tasks through shell .. you can use other consoles from tty 1 to tty6.

tty 7 is GUI [ currently using Desktop ].

Move to tty 1 from current desktop. press ctrl + Alt + F1 . After that use Alt + F2 to go to tty 2 and follow upto F3 F4 F5 F6 and F7 for GUI
