With the period - ./filename

Typing /filename would attempt to reference filename in the / directory, which is the root directory. Typing ./filename attempts to find the file in the current directory.

If you are fammilliar with DOS the principal is very similar, . references the current directory, .. means go up a directory etc. For example typing ../../filename will try to find the filename two directories up, so it you are in /usr/magrute/somepath, it would look in /usr.

Hope this helps.
