The Terminal history will not be written to the history file until you close the current Terminal session, so this approach can be useful for transfering commands from one Terminal session to another. For instance, if you have two Terminals open and enter a complex command in one, to get it to the second Terminal window, simply close the first this will write its history buffer to the history file , and then in the second window type "history -r" to re-read the saved history file. With these actions done, then scroll up using the arrow keys in the second Terminal window you can also use the history function to location the position of the command from the closed Terminal session. 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.
