How can Linux display recently used commands?

In Linux systems, there are several methods available to display recently used commands.

1. By using the history command, you can see a list of all the commands that have been executed by the user in the current session. Simply type “history” in the terminal to view the most recent commands used.
2. By using the Ctrl + r key shortcut: press Ctrl + r in the terminal, then enter a keyword to search for recently used commands. Press Enter to execute the searched command.
3. To check the .bash_history file: A user’s command history is typically stored in the .bash_history file. You can use the command cat .bash_history to view the most recently used commands.
4. You can use ! and – symbols in the command line: !n to execute the nth historical command, !! to execute the previous command, and -n to execute the nth command from the end of history.

These methods can help users view recently used commands, making it easier for users to operate and reuse them.
