where is this directory?

I need to install hdparm to turn my hdd power saving mode off , but the instructions tell me to place the program , in a certain directory so that it starts every time i turn on my mac , but i have looked at all the directorys using finder but i still cannot find them , are they hidden? , the directory i need to install hdparm is below.

Thanks.

"Copy hdapm to somewhere on your system - I suggest /usr/local/bin. If you want to have hdapm run automatically at startup, also copy the hdapm.plist to /Library/LaunchDaemons
Note that you may need to edit hdapm.plist with your desired settings. By default it assumes you installed the hdapm binary in /usr/local/bin, and will set the primary drive (disk0) to the maximum performance APM level."

 

It's hidden under your harddrive, you can go to it from terminal (Terminal shows hidden files) by opening terminal and typing

Code:

cd ..
cd /usr/local/bin

You can now learn how to move files in terminal.... or get leopard to show hidden files...

By typing and opening a new terminal window

Code:

defaults write com.apple.finder AppleShowAllFiles TRUE

killall Finder 

To set it back to normal type that up there ^^^ but change TRUE to FALSE.

 

I manged to find a command to use in terminal , that makes all hidden files/directors visible in finder , so i just had to drag and drop the files to the right directory.

Thanks for the Help.
