A command line argument is a command added to the end of a program file path, that controls how the program is opened.

How to use command line arguments

Windows:

Right-click the Firefox shortcut icon and choose Properties.
Click on the Shortcut tab.
In the Target input box, put the command line argument after the quote. For example

"C:\Program Files\Mozilla Firefox\firefox.exe" "http://www.mozilla.com"

Mac OS:

Go to your Applications/Utilities folder and open Terminal.
Enter the path to Firefox, then a space, followed by the command-line argument. For example,

/Applications/Firefox.app/Contents/MacOS/firefox -ProfileManager

Linux:

Open the Terminal application.
Enter the path to Firefox, then a space, followed by the command-line argument. For example,

firefox -ProfileManager

Command parameters containing spaces must be enclosed in quotes (eg. "Joel User").
Command arguments are not case sensitive.
Command parameters may or may not be case sensitive, depending on the OS and the command.
Command parameters are separated from each other by one or more space, and parameters are separated from arguments by one or more spaces.
