DOS FC

An external command that compares two files for content. .EXE, .COM, .SYS, .OBJ, .LIB and .BIN files are compared byte for byte, otherwise, comparison is line by line. To compare text files FILE1 and FILE2, type:

 fc file1 file2        blank areas must match
                        character for character

 fc file1 file2 /w     blank areas can be of
                        different sizes

 fc file1 file2 /a     show only start and end
                        text on mismatches

Mismatches in ASCII files show as:

  ***** first file
  start
  ...
  ...
  end
  ***** second file
  start
  ...
  ...
  end
  *****

To compare program files ABC.EXE and XYZ.EXE, type:

         fc abc.exe xyz.exe

Mismatches in binary files show as:

         AAAAAAAA BB BB

 A = Hex location from start of file.
 B = Hex characters in first and second files.
