How to use a pager?

A pager is a program that allows you to view (but not edit) the content of files or command output one screen at a time. The most common pager is less. Here’s how to use it:

Basic Usage:

Viewing Output: You can pipe the output of a command to less. For example:
```
ls --help | less
```
Navigating in less:
- Scroll Down: Use the Down arrow key or Space to scroll down one page.
- Scroll Up: Use the Up arrow key or b to scroll up one page.
- Search: Press /, type your search term, and press Enter to find text.
- Exit: Press q to quit less.

Additional Tips:

You can also use more as a simpler pager, but it has limited navigation options compared to less.
To view a file directly with less, you can run:
```
less filename.txt
```
