In the Linux Bash shell, the history of commands is kept in the ~/.bash_history file by default. The commands you type are not transferred to this file instantly.

Saving Command History in Linux

You can use the history -a command to save commands from your active session to the ~/.bash_history file.

Deleting Command History in Linux

You can use the history -c command to delete the commands you wrote in the active session from the history. In order to delete the entire history, you need to clean the files where the history records are kept. If you are using the default settings, simply delete the ~/.bash_history file.

Of course, it's assumed that the shell you are using is Bash.
