The cat command in Linux is used to display the contents of a file directly in the terminal.

In the screenshot, the command cat poems.txt was executed from the ~/Documents directory.

The cat command instructs the system to read the file poems.txt and print its contents line by line on the screen.

The output shows the poem Ozymandias by Percy Shelley, formatted exactly as it appears in the file.

The cat command is useful for quickly viewing text files without opening them in an editor.

It can also be used for concatenating multiple files, creating new files, and appending content to existing files.
