Add flag to output symlink instead of target #100

Closed optix2000 closed 2 years ago

optix2000 commented 2 years ago

It would be nice to have a flag to report on the symlink name instead of the target, or treat symlinks as the target files themselves. This would fill a niche where symlinks provide an alternative name that's more useful than the target file name. This also allows flcones to list duplicate symlinks so that they can be cleaned up when the target files are removed.

Say you have the following files structure:

Where /a/file and /b/file are identical files. /c/symlink is a relative symlink to /a/file.

mkdir a b c
dd if=/dev/urandom of=a/file bs=1M count=10
cp a/file b/file
ln -s ../a/file c/symlink

If you use --follow-links, fclones will report on the target file /a/test instead of /c/symlink.
