Leave terminal free
 

Hi guys, it's simple question but I can't find the answer anywhere.

How to open a file or program using command line and leave the terminal free? Every time I open a file using the command line I have to open a new terminal to do other things.

Thanks

Add an ampersand to the end of the line, e.g.:
... this pushes the job into the background (it runs in a sub-shell). If you have already launched the program, hit Ctrl-Z to stop it temporarily, then type bg and hit return to restart it in the background.

In each case, you will be given a job id and its process number. To get a summary of background tasks in a particular shell, run jobs. You can address each job by its number preceded by a %, e.g. kill %2 to terminate the second background job.

Thanks!
