print quick usage details to the screen.
More verbose output. If specified once, every hardlinked
file is displayed, if specified twice, it also shows every comparison.
Quiet mode, don’t print anything.
Do not act, just print what would happen.
Only try to link files with the same (basename).
It’s strongly recommended to use long options rather than -f
which is interpreted in a different way by others hardlink
Link/compare files even if their mode is different. This
may be a bit unpredictable.
Link/compare files even if their owner (user and group)
is different. It is not predictable.
Link/compare files even if their time of modification is
different. You almost always want this.
Only try to link files with the same extended
Among equal files, keep the file with the highest link
Among equal files, keep the file with the lowest link
Among equal files, keep the oldest file (least recent
modification time). By default, the newest file is kept. If --maximize
or --minimize is specified, the link count has a higher precedence than
the time of modification.
-x, --exclude regex
A regular expression which excludes files from being
compared and linked.
-i, --include regex
A regular expression to include files. If the option
--exclude has been given, this option re-includes files which would
otherwise be excluded. If the option is used without --exclude, only
files matched by the pattern are included.
-s, --minimum-size size
The minimum size to consider. By default this is 1, so
empty files will not be linked. The size argument may be followed by
the multiplicative suffixes KiB (=1024), MiB (=1024*1024), and so on for GiB,
TiB, PiB, EiB, ZiB and YiB (the "iB" is optional, e.g.,
"K" has the same meaning as "KiB").
