     Name
          bdiff - compares files too large for diff(C)


     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 (or file2) 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.

     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.
