In addition to referencing the history by number, you can do so by name. For example, if you have run a command that begins with "pico" to invoke this editor on a document but since then have changed directory or listed directory contents a few times, you can immediately repeat the command that began with "pico" by the following command:.

This can be used to locate the last command that begins with the provided text, but a final approach here is to repeat the last command that includes the mentioned text, which may be convenient to pick out one of many commands that were run with "sudo. The question marks here are like wild cards, so you can remove the one at the end to have the first command run that ended in the included string, which might be a convenient way to re-edit a specific script file if you have just run commands to edit a number of different scripts.

A similar approach to the exclamation point can be done by entering the command "fc -s" alone or followed by the name of the prior command to run.

This can be aliased or scripted as a separate command, but is a bit redundant to the use of the exclamation point.

After you scroll through the second window's history buffer it will start revealing the commands in the history file, with the first one being the complex command from the initial Terminal window.

Using the history in the manners mentioned can be useful, but in addition you may wish to remove an entry or two from the history, or clear it completely if needed. To do this, you can either close the Terminal windows and then remove the history file, or in what is a simpler approach, run "history -c" in the Terminal to clear the history, followed by entering "history -w" to write the now empty history file.

These steps will clear the entire history, which may not always be desired, especially if you only wish to remove a single command that perhaps shows the location of a private file or is one you would perhaps not wish to inadvertently run again.
