To stop the cat command in Linux, you can use the CTRL + C keyboard shortcut. This will terminate the cat command and return you to the command prompt.
For example, if you are running the cat command to display the contents of a file and you want to stop it, you can press CTRL + C on your keyboard. This will terminate the cat command and return you to the command prompt.
You can also use the q key to stop the cat command if it is running in less mode. To use less mode, you can use the cat command with the -less option:
cat -less <file>
This will open the file in less mode, and you can use the q key to exit the cat command and return to the command prompt.
