Probably not the best route, but it works just as good without scripts, open Terminal window and type: Code: defaults write com.apple.finder AppleShowAllFiles TRUE "force quit" Finder. in %home folder% trash .bash_history file and delete contents of .bash_history folder and lock (Get info, and tick "Locked") - In Terminal, type history -c (probably not required) - reverse the showing of files as above, but use FALSE instead, and re-launch Finder again. All history will never be kept across any session of Terminal. Although the .bash_history fill will still be created, the fact .bash_folder cannot be written to because its locked, your good to go You'll get an error every time Terminal opens mkdir... but that is nothing to worry about. If u wish to re-enable history, just show all files again and unlock the folder.
