--man the manpage
a short help
the version (CVS) of the program
do just nothing, just print out (implies -v)
just what the name says
link the identical files together
Use the old output of this script
Don’t check that file owner and permissions match
Define the dir to check (you may specify more than one)
finddup search the working directory and all files below on the same
partition for duplicate files.
finddup can optional hardlink such files to save space.
Files size 0 will not be reported or hardlinked as this might give
This is a complete rewrite of the finddup in perl to handle several
- Allow spaces and other characters in filenames
- be faster
- include nodup in same script
- Handle files that already have other hardlinks in the same tree
- Several improvements
If started as nodup or nodup.pl the script will act like started with
options --link and --oldresult
