What is $'more?

"more" is a command commonly used in computer operating systems and software to view the contents of a file or to display text on the terminal or console. It is a basic pager program that allows users to scroll through the contents of a file, page by page.

The "more" command is a successor to the older "less" command and is often used interchangeably with it. The purpose of these commands is to handle large amounts of text that cannot fit on a single screen.

By default, when the "more" command is used, it displays text one screen at a time. The user can scroll through the text using various keyboard commands such as pressing the spacebar to move forward one screen, pressing the Enter key to move forward one line, or pressing the 'q' key to exit the program.

The "more" command also provides additional functionality such as searching for specific text within a file, displaying line numbers, and navigating backwards through the text.

Overall, the "more" command is a simple and widely-used tool for viewing and navigating through text files on Unix-like operating systems. It is often used in combination with other commands in shell scripts or during system administration tasks.
