bdiff --
big diff
Synopsis
bdiff file1 file2 [n] [-s]
Description
bdiff
is used in a manner analogous to
diff
to find which lines in
file1
and
file2
must be changed to bring the files into agreement.
Its purpose is to allow processing of files too large for
diff.
If
file1 (file2)
is
-,
the standard input is read.
Valid options to bdiff are:
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, that this does not suppress possible diagnostic messages
from diff, which bdiff calls.
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 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 that
because of the segmenting of the files,
bdiff
does not necessarily find a
smallest sufficient set of file differences.
