Heh, good question!  :)

The asterisk after the filename indicates that it is an executable file.
Similarly a directory would have a "/" after it.  This type of output is
caused by doing a "ls -F."  Debian sets up the following aliases:

	unalias ls
	alias   ls      'ls-F -C'

It seems that "ls-F" (no space after ls) is a shell built-in command.  As
stated above, shells that don't have this built-in command can simply use
"ls -F" (with a space after ls) to produce the desired output.
Incidentally, here is an excerpt from the ls man page:

       -F, --classify
              Append a character to each file name indicating the
              file type.  For regular files that are  executable,
              append a `*'.  The file type indicators are `/' for
              directories, `@' for symbolic links, `|' for FIFOs,
              `=' for sockets, and nothing for regular files.
