Zenity: A Guide to Creating GTK+ Dialogs in Linux Command Line

When working in the Linux command line, sometimes you may need to display dialog boxes to interact with the user, such as asking for input, providing information, or confirming actions. Zenity is a handy tool that allows you to create GTK+ dialogs from the command line, making it easy to add graphical interfaces to your scripts and applications.

Zenity is a simple and easy-to-use tool that allows you to create various types of dialog boxes, such as text entry dialogs, file selection dialogs, message dialogs, progress bars, and more. These dialogs are created using the GTK+ toolkit, which is a popular toolkit for creating graphical user interfaces on the Linux platform.

To use Zenity, you simply need to run the zenity command followed by the type of dialog you want to create. For example, to create a simple message dialog, you can run the following command:

zenity --info --text="Hello, World!"

This will display a message dialog with the text "Hello, World!" and an "OK" button for the user to close the dialog.

Zenity also allows you to retrieve user input using text entry dialogs. For example, you can run the following command to prompt the user to enter their name:

zenity --entry --text="Enter your name:"

This will display a text entry dialog with a text box for the user to enter their name. You can then capture the user’s input and use it in your script or application.

In addition to text entry dialogs, Zenity also supports file selection dialogs, which allow users to select files and directories using a graphical interface. For example, you can run the following command to prompt the user to select a file:

zenity --file-selection --title="Select a file:"

This will display a file selection dialog with a "Cancel" and "Open" button for the user to select a file.

Zenity also supports other types of dialogs, such as progress bars, list dialogs, color selection dialogs, and more. You can explore the full range of dialog types supported by Zenity by running the following command:
