8. less

If you are viewing text files larger than a simple output, less is more. (There is actually a command called more that does something similar, so this is ironic.) The text is displayed in a paged manner, so you can navigate through a text file page by page.

Go ahead and look at the contents of a file with less. Once you’re in the less command, you can actually use other keyboard commands to navigate in the file.

$ less /home/pete/Documents/text1

Use the following command to navigate through less:


  • q - Used to quit out of less and go back to your shell.

  • Page up, Page down, Up and Down - Navigate using the arrow keys and page keys.

  • g - Moves to beginning of the text file.

  • G - Moves to the end of the text file.

  • /search - You can search for specific text inside the text document. Prefacing the words you want to search with /

  • h - If you need a little help about how to use less while you’re in less, use help.

Exercises

Run less on a file, then page up and around the file. Try searching for a specific word. Quickly navigate to the beginning or the end of the file.
