Directories

When you log in, you are automatically placed in your home directory (which is referred to as ~ or $HOME). The following are some of the most useful directory commands and their uses:

• pwd - `Print Working Directory', displays the current working directory on the screen.
• cd - change directories. Typing cd by itself is an easy way to get back to your home directory.
• ls - lists the contents of a directory. Useful options are l (long listing) and a (lists `dot' files---hidden files such as `/.rhosts').
• mkdir - create a new directory. If the new name doesn't start with a /, it is taken relative to the current directory.
• rmdir - deletes an empty directory. If it isn't empty, you must either delete everything in it separately or use the command rm -r.
• ln - establishes a link between two files (especially between directories) to allow direct access of one from the other.
