history: history [-c] [-d offset] [n] or history -anrw [filename] or history -ps arg [arg...]

        list
      -w        write the current history to the history file
        and append them to the history list
    
      -p        perform history expansion on each ARG and display the result
        without storing it in the history list
      -s        append the ARGs to the history list as a single entry

If FILENAME is given, it is used as the history file. Otherwise, if $HISTFILE has a value, that is used, else ~/.bash_history.

If the $HISTTIMEFORMAT variable is set and not null, its value is used as a format string for strftime(3) to print the time stamp associated with each displayed history entry. No time stamps are printed otherwise.

Exit Status:
Returns success unless an invalid option is given or an error occurs.
