User Commands bdiff(1)
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).
