Function Details

[hide private]

cmp(f1, f2, shallow=1)

Compare two files.

Arguments:

f1 -- First file name

f2 -- Second file name

shallow -- Just check stat signature (do not read the files).
           defaults to 1.

Return value:

True if the files are the same, False otherwise.

This function uses a cache for past comparisons and the results,
with a cache invalidation mechanism relying on stale signatures.

cmpfiles(a, b, common, shallow=1)

Compare common files in two directories.

a, b -- directory names
common -- list of file names found in both directories
shallow -- if true, do comparison based solely on stat() information

Returns a tuple of three lists:
  files that compare equal
  files that are different
  filenames that aren't regular files.
