I am trying to create a very simple bash script with a GUI. I want it to bring up a dialog where the user can use the arrow keys to select a function, it will complete it and then return to the menu.
I started of using dialog as it will easy to list options but the script always ends once 1 action is complete.
Here is what I have so far :
dialog --menu "Task to perform" 10 30 3 1 This 2 That Office 3 Exit
Can anyone point me to the way of returning to the menu? (or another way!)
You don't need 3 Exit as an option as dialog already generates a "Cancel" button. You could do a loop to display the dialog box until the user presses the cancel button :
(Note: some of my code sample is taken from this answer)
#!/bin/bash
#we start the loop....
while [[ "$dialog_exit" -ne 1 ]]; do
#we force the redirection of the output to the file descriptor n°1 with the --fd-output 1 option
dialog_result=$(dialog --clear --menu "Task to perform" 10 30 3 1 "This task" 2 "That task" 3 "Yet another task" --fd-output 1);
#we store the exit code. If the user pressed cancel, exit code is 1. Else, it is 0.
dialog_exit=$?;
case "$dialog_result" in
1) echo "task 1";;
2) echo "task 2";;
3) echo "task 3";;
"") echo "action when cancel";;
esac
done
