Which command shows the history of previously executed commands?

The command that shows the history of previously executed commands is "history." When you enter this command in a Linux terminal, it retrieves and displays a list of commands that you have entered in that terminal session. This feature is beneficial for recalling previous commands, which can save time and effort in re-typing complex or frequently used commands.

The command history is also stored in a file, typically called .bash_history in the user's home directory for bash users, allowing you to access your command history even after closing the terminal. This utility is a standard feature across many Linux distributions and shells, enabling users to gain insights into their past command usage and improve their command-line efficiency.
