First, open a terminal window by double clicking on the desktop icon that says “terminal” or the square icon that looks vaguely like a computer monitor at the top of the real screen. Type UNIX commands in this window. You can select text with the mouse, but you can only move the cursor by using the arrow keys and you can only type in the last line. To recall a command you typed in earlier, use the up arrow key until that command appears at the prompt.

Some Commands Include:

• ls = list the contents of your current directory

101}ls

• <path> can include a directory in your current directory as in the example above, “..” which sends you up one directory (cd ..), or a path all the way from the computer hard drive, e.g. /share/Data/VolumeData. The initial “/” indicates that the path to the directory you want starts at the hard drive level.
• To make a directory, use the command “mkdir <directory name>” as in

114}ls

• To copy a file, use “cp <file name> <path and new file name>”.
• To copy a bunch of files to a directory, you can use the wild card “*”. To copy files from a local directory to a remote directory, this is one format: cp *.* <path> and an example:

117}cd A_test_dir/
118}ls
119}cd ../Public/
120}ls

121}cp *.* ../A_test_dir/
122}cd ../A_test_dir/
123}ls
