    Help with fc and designator !

    Use the fc command to show every command you have typed since the most recent ps command, and only those commands.

    Use the fc command with the -s option to re-execute that ps command.

    Use ! to reference the most recent df command you did. Do not use the history number.

    Use ! to redo the sixth preceding command.

    Use ! to redo the most recent command that contained the letters wd.

    I need help with 5 of these questions. I know they're "easy" but I can't seem to find anything about it from my book.

    Is this a homework question? Per the forum rules, that is not allowed.

    A suggestion on your question: read the bash man page (command in a terminal is man bash) and read up on the fc built-in command.
