How to Use History Command in Linux

The “history” command reveals the list of the command that the current user has been invoked. The command accepts passing a pattern as an argument to sort specific commands from the history.

General syntax for history command:

history [OPTIONS...]
Show used commands
history [number]

This command displays a limited number of previously executed commands.

Example: To print the last five commands you have used, type history 5.

Delete commands from history list
history -d [number]

Use the -d option to delete commands from the history list.

Example: Removing the fifth (5) command from the history list.

Search used command within history
history | grep [text]

The history | grep command helps you find commands that match a text pattern.

search within history
Clearing the history list

Execute the command with event number
