You can access all of the files and directories in your file system from the Command Tool. Use of the Command Tool requires familiarity with the operating system and with your file system.
In the sample session that follows, the cd command changes directories to your home directory, the mkdir command creates a new directory there, and the cp command copies that directory to a new directory with a different name. You execute each command when you press Return at the end of the command line.
