bdiff(1) General Commands Manual bdiff(1) Name bdiff - big file differential comparator Syntax bdiff file1 file2 [n] [-s] Description The command is used to find lines that must be changed in two files to bring them into agreement. Its purpose is to allow processing of files that are too large for The command ignores lines common to the beginning of both files, splits the remainder of each file into n-line segments, and invokes upon corresponding segments. The value of n is 3500 by default. If the optional third argument is given and if 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 causing it to fail. The output of the command is the same as the output of the command: line numbers are adjusted to account for the segmenting of the files to make it look as if the files had been processed whole. Note that because of the segmenting of the files, does not necessarily find the smallest sufficient set of file differences. If either file1 or file2 is -, the standard input is read.

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
