A quick guide to the `history` command, used to view the command line history
Every time we run a command, that’s memorized in the history.
You can display all the history using:
history
This shows the history with numbers:
You can use the syntax !<command number>
to repeat a command stored in the history, in the above example typing !121
will repeat the ls -al | wc -l
command.
Typically the last 500 commands are stored in the history.
You can combine this with grep
to find a command you ran:
history | grep docker
To clear the history, run history -c
The
history
command works on Linux, macOS, WSL, and anywhere you have a UNIX environment
