     NAME
          bdiff - big diff

     SYNOPSIS
          bdiff file1 file2 [n] [-s]

     DESCRIPTION
          Bdiff is used like diff(1) to find which lines must be
          changed in two files to bring them into agreement.  It lets
          you process files that are too large for diff.  Bdiff
          ignores lines common to the beginning of both files, splits
          the rest of each file into n-line segments, and invokes diff
          upon corresponding segments.  The value of n is 3500 by
          default.

          If you give the optional third argument and it is numeric,
          it is used as the value for n.  This is useful in those
          cases in which 3500-line segments are too large for diff,
          causing it to fail.  If file1 or file2 is -, the standard
          input is read.  The optional -s (silent) argument specifies
          that no diagnostics are to be printed by bdiff. Note,
          however, that this does not suppress possible exclamations
          by diff.  If both optional arguments are specified, they
          must appear in the order indicated above.

          The output of bdiff is exactly that of diff, with line
          numbers adjusted to account for the segmenting of the files
          (that is, to make it look as if the files had been processed
          whole).  Note that because of the segmenting of the files,
          bdiff does not necessarily find the smallest sufficient set
          of file differences.

     FILES
          /tmp/bd?????  possible temporary file produced.
