DOS Comp

DOS Comp

An external command that compares two files for identical content and reports up to 10 mismatches. In DOS 6, this command is no longer installed, although it still resides on the DOS 6 Supplemental Disk. To compare file RED with GREEN, type:

           comp red green

Mismatches are reported as follows:

     Compare error at OFFSET AA
     File 1 = BB
     File 2 = BB

  AA = location of characters
  BB = characters (in hex)

As of DOS 5, these optional switches can be added to the command:

    /a   Show ASCII characters (not hex)
    /l   Display line numbers (not offset)
    /c   Non case-sensitive compare
