SYNTAX
bdiff file1 file2 [n] [-s]
DESCRIPTION
Bdiff is used like diff(1) to find which lines must be changed in
two files to bring them into agreement. It lets you process
files that are too large for diff. Bdiff ignores lines common to
the beginning of both files, splits the rest of each file into
n-line segments, and invokes diff upon corresponding segments.
The value of n is 3500 by default.
If you give the optional third argument 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.
If file1 or file2 is -, the standard input is read. The optional
-s (silent) argument specifies that no diagnostics are to be
printed by bdiff. Note, however, that this does not suppress
possible exclamations by diff. 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 the smallest sufficient set of file differences.
FILES
