     Name
          bdiff - Compares files too large for diff.

     Syntax
          bdiff file1 file2 [ n ] [-s]

     Description
          bdiff compares two files, finds lines that are different,
          and prints them on the standard output.  It allows
          processing of files that are too large for diff.  bdiff
          splits each file into n-line segments, beginning with the
          first nonmatching lines, and invokes diff upon the
          corresponding segments.  The arguments are:

          n    The number of lines bdiff splits each file into for
               processing. The default value is 3500. This is useful
               when 3500-line segments are too large for diff.

          -s   Suppresses printing of bdiff diagnostics.  Note that
               this does not suppress printing of diagnostics from
               diff.

          If file1 (orfile2) is a dash (-), the standard input is
          read.

          The output of bdiff is exactly that of diff.  Line numbers
          are adjusted to account for the segmenting of the files, and
          the output looks as if the files had been processed whole.

     Files

     Notes
          Because of the segmenting of the files, bdiff does not
          necessarily find a smallest sufficient set of file
          differences.

          Specify the maximum number of lines if the first difference
          is too far down in the file for diff and an error is
          received.
