BDIFF(C) XENIX System V BDIFF(C)
Name
bdiff - Compares files too large for diff.
Syntax
bdiff file1 file2 [ n ] [-s]
Description
bdiff compares two files, finds lines that are different,
and prints them on the standard output. It allows
processing of files that are too large for diff. bdiff
splits each file into n-line segments, beginning with the
first nonmatching lines, and invokes diff upon the
corresponding segments. The arguments are:
n The number of lines bdiff splits each file into for
processing. The default value is 3500. This is useful
when 3500-line segments are too large for diff.
-s Suppresses printing of bdiff diagnostics. Note that
this does not suppress printing of diagnostics from
diff.
If file1 (or file2 ) is a dash (-), the standard input is
read.
The output of bdiff is exactly that of diff. Line numbers
are adjusted to account for the segmenting of the files, and
the output looks as if the files had been processed whole.
Files

Notes
Because of the segmenting of the files, bdiff does not
necessarily find a smallest sufficient set of file
differences.
Specify the maximum number of lines if the first difference
is too far down in the file for diff and an error is
received.
