Shell script – Zenity list dialog tutorial

On this Shell script tutorial, I am going to learn how to show a list dialog using Zenity. Zenity list dialog provide an interesting way to show a list box/list dialog using Shell script. See the example below:

Create a new file

[codesyntax lang=”bash”]

nano test.sh

[/codesyntax]

Insert the following lines

[codesyntax lang=”bash”]

cd /home/dhani/Downloads
answer=$(ls *.deb | zenity --list --title "Zenity tutorial" --column "List of files")
case $? in
0) 
if ["$answer" == ""]; then
zenity --warning --text "You choose nothing"
else
zenity --info --text "you choose $answer"
fi;;
1)
;;
*)
zenity --warning --text "No file selected";;
esac

[/codesyntax]

Then save it and make it executable then, run it.

[codesyntax lang=”bash”]

chmod +x test.sh
sh test.sh

[/codesyntax]

The code above will list any files with DEB extension under /home/dhani/Downloads directory.

When you click a DEB file from the list and press OK, it will display an info dialog.

When OK button pressed without selecting any file, it will show

Thank you see you on the next Shell Script tutorial.
