getting back to [user@domain ~]$ after starting a program (terminal)


Hi guys BASIC question time.

-after I run let's say etherape from a terminal window, I get just flashing cursor waiting at the bottom.

How do I get back to [user@domain ~]$ ?

Been googling this for a while but it's all about exiting a program or terminal itself.


Cheers!

you need to use the & argument. for example,
Code:
user@domain ~$ /usr/bin/etherape &

You are into what is called "job control" territory...
Basically
Ctrl + Z - to pause the current process.
bg - to continue process in background.
fg - bring process back to foreground.


But I would recommend reading this link for a full description of linux job control http://linuxcommand.org/lts0080.php

Ok that does it.

As I understand the & character suggests that you are not finished and another commands may follow. That's pretty cool.
Btw I just type etherape instead of the full path. I guess the lazy way is not the best way to get somewhere...

Thanks

Thanks for the 'point' (-:
I usually just type the name of the program too, but i'm not familiar with ethrape and honestly had never heard of it so i put the full path just to be clear.
Lasty, lazyness isn't all bad, people come up with brilliant ideas so they can continue being lazy and lead more convenient life styles.

in addition: the & makes the program go to the background, if you want another cursor in a different window but you only have one you might be interrested in screen. I use it for this torrent downloader for example.
I run:
Code:
screen rtorrent
and if I want to let it run in the background I press ctrl+a and then d for detach.
then if I want to get the screen back I run
Code:
screen -r
And I go back to where I was.

Usually screen is used for running something server side that you can leave running while you kill the ssh connection. (use command pstree to see why) screen doesn't run on the ssh session but directly on the root of the process tree.

I hope this is of any use to you.

You should also lookup the nohup cmd.
This (in combination with '&') allows you to logout of that session and the cmd will continue to run.
Similar to screen, but more basic.
Typically (and collecting stdout & stderr)
Code:
nohup some_cmd >cmd.log 2>&1 &
