LINUX BASH GUI Scripting Using Zenity
In this lecture, I demonstrated how to write BASH Shell Scripting to create Menus and Widgets (GUI) using Zenity.
In addition, I use the Linux "strace" command to check to find the authentication (login and password) from the Process ID of a none-secure process that takes the login of "Jamesbond" with the password of "Double07" as a demonstration and detects it in the output of the write functions of the tracing the PID of the zenity p;process. The strace clearly shows the password that was typed in during the authentication in the GUI interface so we need to be more careful to encrypt any authentication mechanism using md5, or the latest version of TLS 1.2 or later depending on when you use it.
