Linux – How to show a GUI message box from a bash script in linux

bashgtklinuxscriptingubuntu

I'm writing a few little bash scripts under Ubuntu linux. I want to be able to run them from the GUI without needing a terminal window to enter any input or view any output.

So far the only input required is a password for sudo – and gksudo handles that fine.
But I haven't found an easy way to show a message box yet. Is there some kind of 'gkmessage' command available? I'd prefer something present in a default Ubuntu install, but I don't mind installing a new package if necessary.

Best Solution

If you are using Ubuntu many distros the notify-send command will throw one of those nice perishable notifications in the top right corner. Like so:

notify-send "My name is bash and I rock da house"

B.e.a.utiful!
