Option

An option may refer to any of the following:

1. An option is a choice presented to a user. For example, when closing a program, you may be prompted to save any open files with unsaved changes. Clicking "Yes" saves the file and closes the program; clicking "No" closes the program without saving the files, and your changes are discarded. When dealing with several options in a GUI (Graphical User Interface), the user often navigates the options through an options menu.

2. With HTML (HyperText Markup Language), the <option> tag designates a list item in the <optgroup>, <datalist>, or <select> elements.

3. Option is a short way of saying Option key.

4. With a command line, like the Linux shell, a command option adds one or more settings to a command. For example, typing the following ls command in Linux displays a generic listing of the directories and files in the current directory.

ls

Viewing the commands help file with "--help" or using the man command shows all available options. Using this information, we can see the option "-t" to sort files by most recently modified and "-x" to list files by line and not column. Either of these switches can be used alone (e.g., "ls -t") or combined, as shown in the following example.

ls -tx
