suffixes - list of file suffixes


   It  is  customary  to  indicate  the  contents  of a file with the file
   suffix, which consists of a period, followed by one  or  more  letters.
   Many  standard  utilities, such as compilers, use this to recognize the
   type of file they are dealing with.  The make(1) utility is  driven  by
   rules based on file suffix.

   Following is a list of suffixes which are likely to be found on a Linux
