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 cor-
       responding 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 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 diagnos-
		tic 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
