SYNOPSIS
     bdiff filename1 filename2 [ n ] [ -s ]

DESCRIPTION
     bdiff is used in a manner analogous to diff  to  find  which
     lines  in  filename1  and filename2 must be changed to bring
     the files into agreement.  Its purpose is to allow  process-
     ing  of  files too large for diff.  If filename1 (filename2)
     is -, the standard input is read.

     bdiff ignores lines common to the beginning of  both  files,
     splits  the remainder of each file into n-line segments, and
     invokes diff on corresponding segments.   If  both  optional
     arguments are specified, they must appear in the order indi-
     cated 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:   Because  of  the  segmenting of the files,
     bdiff does not necessarily find a smallest sufficient set of
     file differences.

OPTIONS
     n         The number of line segments.  The value  of  n  is
               3500  by  default.  If the optional third argument
               is given 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.

     -s         Specifies that no diagnostics are to  be  printed
               by  bdiff  (silent  option).  Note:  However, this
               does not  suppress  possible  diagnostic  messages
               from diff, which bdiff calls.
