Linux Command Line Tutorial


In this video, we will learn how to use less command. less is a command-line utility that displays the content of a file or a command output, one page at a time. The less command is mostly used for opening large files.

The general syntax for using less command is:

less [options] filename

It is also possible to use less with other commands output.

ls /etc | less

When opening a file that is too large to fit in one page, you will see the colon at the bottom of the screen. What makes less more appealing is its ease of file navigation.
