I really like the -S idea. Especially for verifying
CDs and downloads. But a suggestion:
The way one describes the dir affects the checksum of
the dir. E.g.:
jacksum -S .
jacksum -S c:\mydir
jacksum -S \mydir
all give different hash signatures for the same
directory. So someone besides the creator needs to
know how to describe the dir in order to generate the
Perhaps an option to use file.getCanonicalPath()
instead of the argument. Which might deal with the
three examples above. But it wouldn't help with me (
the author ) doing a -S on e:\ (my CD-ROM drive) and
the recepient doing a -S but they have copied the files
to c:\tmp or their drive is f: or /mnt/...
