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

Question

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

Answer 1

Here's a little Tcl script that will do what you want. The Wish interpreter should be installed by default on Ubuntu.

#!/usr/bin/wish
pack [label .msg -text [lindex $argv 0]]
pack [entry .ent]
bind .ent  { puts [.ent get]; destroy . }
focus .ent

Call it like this:

myanswer=`gui-prompt "type your answer and press enter"`
