File Types

The ls -F command shows a graphical description of the file type. All executable files have a * after the filename. All directories have a / after their filename. It is important to realize that these are only symbols and are not a part of the filename or directory name. Therefore when referencing a filename in a UNIX command do not include these symbols. For example, here is the contents of Joe's home directory:
math joe % ls -F
RMAIL* thesis/
math joe %

Note: All new accounts in the Math Department have this option as the default action, so that new users can easily see what types of files they have in their directory.
