command run on another terminal

[kr651129]

Ok, weird question, but I was just wondering if this is possible. Let's say I have two terminals open and I run a command on one, while it's running is it possible to check the last executed command on that other terminal? A random thought I had today and wouldn't mind knowing.

Look into something called a named pipe.

Read through the snp(4) and watch(8) man pages.

I've tested this with virtual consoles (outside of X). Haven't tried using virtual terminals inside X.

You can do it easy by checking the history file on your login shell.

You can do it easy by checking the history file on your login shell.

That only shows which commands have been started. It doesn't show if they're still running and you also can't 'see' the output.

Simplest solution would be to use sysutils/tmux or sysutils/screen. I definitely recommend tmux(1).

On the second terminal you can tmux att and you'll see exactly the same tmux session as on the other terminal. You can even detach the session completely and everything running inside it will keep running. Easily picked up again from another terminal or even a remote SSH. Quite handy if you work on a remote machine that has a crappy connection.

Not sure if it's what you're after, but w(1)() will show you the last command executed on each tty.

I think also sysutils/pstree can do the trick.
