I am new to Ubuntu. I have used Sublime Text. I have realized that after I open Sublime Text from the Terminal, if I close the terminal the application keeps running. The same isn't true for other applications like geany.

After I open the application from terminal, when I close the terminal the application also closes. I have tried &exit like geany &exit. But this isn't what I am looking for.

How can I keep geany running even after I close it?

From a terminal window, type in

nohup geany > /dev/null

or

nohup geany >/dev/null &

nohup allows the application to be ran and immune to hangups, so closing the terminal window would have no effect on the application being run. Adding the >/dev/null to the command prevents the creation of a nohup.out in each directory the application is being run from.

From the man page:

NAME
       nohup - run a command immune to hangups, with output to a non-tty

SYNOPSIS
       nohup COMMAND [ARG]...
       nohup OPTION

    Maybe nohup geany > /dev/null or nohup geany > /dev/null &, to prevent the creation of a nohup.out file in the current working directory each time the command is run – kos Jul 19 '15 at 1:26
  • No problem, upvoted already (by the way in general feel free to not even bother crediting me in the post for such a little enhancement!) – kos Jul 19 '15 at 1:33

    @kos OK, I removed it. But thanks again for the reminder. There are times that I forget some of the simple things to stop the log output creation. I really look forward to good suggestions from others. =) – Terrance Jul 19 '15 at 1:36

    Often the run output is helpful/important for monitoring status or keeping track of what was done. It this case you would want to use something like nohup run1_cmd.sh > run1.out . – Steven C. Howell Jul 19 '15 at 3:53

As an alternative to nohup you could use the shell builtin disown. disown removes jobs from the job list, and when the shell exists, SIGHUP is not sent to that process.

geany &
disown
exit

You can use exec geany & exit (note the exec and ampersand) if you do not need root and pkexec geany & exit if you need root privileges.
