NAME
      bdiff - big diff
 


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 processing
      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.
 
 USAGE
      See largefile(5) for the  description  of  the  behavior  of
      bdiff  when  encountering  files  greater than or equal to 2
      Gbyte ( 2**31 bytes).
