How to read the contents of a text file in Linux?

To read the contents of a text file in Linux, you can use various commands such as cat, less, or more. Here are some examples:

1. Using cat command:

cat file.txt

This will print the contents of file.txt to your command line.
2. Using less command:

less file.txt

This will allow you to navigate through the contents of file.txt using your arrow keys, and you can quit by pressing q.
3. Using more command:

more file.txt

This will also allow you to navigate through the contents of file.txt, but only using the spacebar key to move forward and the q key to quit.

Note that the cat command is the simplest and most common way to read the contents of a text file in Linux.

Alternatively, you can use a text editor such as nano, vi, or emacs to open and read a text file, but this method is more involved and is better suited for editing files rather than simply reading them.
