bdiff(1)bdiff(1)NAMEbdiff - big diff
SYNOPSISbdiff file1 file2 [ n ] [-s]
DESCRIPTIONbdiff 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.
