If you’re working in Terminal on your Mac, you need to know the most important UNIX commands: those that work with directories, those that work with files, and miscellaneous but commonly used commands.

Folders are called directories in UNIX. Commands that refer to filenames, as most do, assume that you’re talking about files in the working directory. When you open the Terminal window, the working directory is set to your home directory, abbreviated ~. Bash shows you the current working directory and your username to the left of its prompt. The following table lists common directory-related commands.

UNIX Directory Commands
CommandWhat It Does
lsLists the names of the files in the working directory. For more
complete information, use ls –alF (.
cd directorynameChanges the working directory to the one you named.
cd ..Brings you up one directory level.
cdReturns you to your home directory.
pwdDisplays the pathname of the current directory.
mkdir newdirectorynameMakes a new directory.
rmdir directorynameRemoves (deletes) an empty directory.

As in Windows, you can redirect the output of a command to a text file. So if you want a record of the files in a folder, type cd, followed by a space, drag the folder’s icon to the Terminal window, and press Return. Type ls > mydirectorylist.txt and press Return again. A file named mydirectorylist.txt will appear in the folder you chose. You can open the file in TextEdit to see a list of the files in that directory.

This table lists commands commonly used when working with files in the Terminal window.
