The command "pkill --oldest "${firefox}"" is used to terminate the oldest running process of a program named "firefox".
Here's an explanation of the different components of the command:
- "pkill" is a command-line utility that allows you to terminate processes based on their names.
- "--oldest" is an option used with "pkill" to terminate the oldest (longest-running) process among all the instances of the program with the specified name.
- "${firefox}" is a variable that holds the name of the program you want to kill. In this case, it is "firefox".
So, when you execute this command, it will find the oldest running process of Firefox and terminate it.
