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	agree‐
       ment.  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 corre‐
       sponding segments. 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:  Because of the segment‐
       ing 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 possi‐
		ble 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).

FILES
       /tmp/bd?????
