But it might be a good idea to always sort by directory hierarchy (i.e. always either prefer to symlink either up or down a directory tree). > > Anyway, if there isn't something that already does it, I can probably > > just parse the output of one of these programs and do the symlink > > replacement myself. > > That would be the other way. finddup can print out the double files. One issue I have with both finddup and fdupes, is they both don't quote their output very sanely; or at least, in not in a particularly easy manner for parsing (I can do it with a lookbehind regex). For example: $ finddup . 2 './file with spaces' './file1' './file with (parens)' './file with a newline' './file2' './file with 'ticks'' './file with "quotes"' $ fdupes -1 . ./file1 ./file\ with\ a newline ./file\ with\ "quotes" ./file\ with\ 'ticks' ./file\ with\ (parens) ./file\ with\ spaces ./file2 I would LOVE it if it would shell quote the output or something... or if there was a -0 option to delimit things with nulls... or something that could make it work reliably with any filename Anyway, sounds like maybe I should file some wishlist bugs. =) -- Wesley J.

Well I rewritten it from scratch as the original tool had some flaws. It is very easy to add a option for symlinking. But there is a little problem deciding which of the files should be the symlink and which the original.

It's > written in Perl. Well, thanks, I didn't know about this one. But, it does really *have* to be symlinks. I've found a few other tools that do hardlinks. =) Anyway, if there isn't something that already does it, I can probably just parse the output of one of these programs and do the symlink replacement myself. -- Wesley J.

If hardlinks are okay too, see the "perforate" package (I find this package hard to find, since the name is somewhat misleading). It's written in Perl. $ dlocate /usr/bin/finddup perforate: /usr/bin/finddup $ whatis finddup finddup (1) - Find identical files and do something with them $ finddup --help Usage: finddup [options...] --man the manpage -h, --help a short help --version the version (CVS) of the program -n, --noaction do just nothing, just print out (implies -v) -v, --verbose just what the name says -q, --quietbe quiet -l, --link link the identical files together -o, --oldresultUse the old output of this script -i, --ignore-perms Don't check that file owner and permissions match -d, --dir Define the dir to check (you may specify more than one) BYtE Philipp -- Philipp Matthias Hahn <[EMAIL PROTECTED]> GPG/PGP: 9A540E39 @ keyrings.debian.org -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
