bdiff(C)
bdiff --
compare files too large for diff(C)
Syntax
bdiff file1 file2
[ n ] [ -s ]
Description
The bdiff command
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 non-matching 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.
Limitations
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.
