+.SH "NAME"
+hardlink \- link multiple copies of a file
+.SH "SYNOPSIS"
+.sp
+\fBhardlink\fP [options] [\fIdirectory\fP|\fIfile\fP]...
+.SH "DESCRIPTION"
+.sp
+\fBhardlink\fP is a tool which replaces copies of a file with hardlinks, therefore saving space.
+.SH "OPTIONS"
+.sp
+\fB\-h\fP, \fB\-\-help\fP
+.RS 4
+print quick usage details to the screen.
+.RE
+.sp
+\fB\-v\fP, \fB\-\-verbose\fP
+.RS 4
+More verbose output. If specified once, every hardlinked file is displayed, if specified twice, it also shows every comparison.
+.RE
+.sp
+\fB\-q\fP, \fB\-\-quiet\fP
+.RS 4
+Quiet mode, don\(cqt print anything.
+.RE
+.sp
+\fB\-n\fP, \fB\-\-dry\-run\fP
+.RS 4
+Do not act, just print what would happen.
+.RE
+.sp
+\fB\-f\fP, \fB\-\-respect\-name\fP
+.RS 4
+Only try to link files with the same (basename). It\(cqs strongly recommended to use long options rather than \fB\-f\fP which is interpreted in a different way by others \fBhardlink\fP implementations.
+.RE
+.sp
+\fB\-p\fP, \fB\-\-ignore\-mode\fP
+.RS 4
+Link/compare files even if their mode is different. This may be a bit unpredictable.
+.RE
+.sp
+\fB\-o\fP, \fB\-\-ignore\-owner\fP
+.RS 4
+Link/compare files even if their owner (user and group) is different. It is not predictable.
+.RE
+.sp
+\fB\-t\fP, \fB\-\-ignore\-time\fP
+.RS 4
+Link/compare files even if their time of modification is different. You almost always want this.
+.RE
+.sp
+\fB\-X\fP, \fB\-\-respect\-xattrs\fP
+.RS 4
+Only try to link files with the same extended attributes.
+.RE
+.sp
+\fB\-m\fP, \fB\-\-maximize\fP
+.RS 4
+Among equal files, keep the file with the highest link count.
+.RE
+.sp
+\fB\-M\fP, \fB\-\-minimize\fP
+.RS 4
+Among equal files, keep the file with the lowest link count.
+.RE
+.sp
+\fB\-O\fP, \fB\-\-keep\-oldest\fP
+.RS 4
+Among equal files, keep the oldest file (least recent modification time). By default, the newest file is kept. If \fB\-\-maximize\fP or \fB\-\-minimize\fP is specified, the link count has a higher precedence than the time of modification.
+.RE
+.sp
+\fB\-x\fP, \fB\-\-exclude\fP \fIregex\fP
+.RS 4
+A regular expression which excludes files from being compared and linked.
+.RE
+.sp
+\fB\-i\fP, \fB\-\-include\fP \fIregex\fP
+.RS 4
+A regular expression to include files. If the option \fB\-\-exclude\fP has been given, this option re\-includes files which would otherwise be excluded. If the option is used without \fB\-\-exclude\fP, only files matched by the pattern are included.
+.RE
+.sp
+\fB\-s\fP, \fB\-\-minimum\-size\fP \fIsize\fP
+.RS 4
+The minimum size to consider. By default this is 1, so empty files will not be linked. The \fIsize\fP 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").
+.RE
+.SH "ARGUMENTS"
+.sp
+\fBhardlink\fP takes one or more directories which will be searched for files to be linked.
+.SH "BUGS"
+.sp
+The original \fBhardlink\fP implementation uses the option \fB\-f\fP to force hardlinks creation between filesystem. This very rarely usable feature is no more supported by the current hardlink.
+.sp
+\fBhardlink\fP assumes that the trees it operates on do not change during operation. If a tree does change, the result is undefined and potentially dangerous. For example, if a regular file is replaced by a device, hardlink may start reading from the device. If a component of a path is replaced by a symbolic link or file permissions change, security may be compromised. Do not run hardlink on a changing tree or on a tree controlled by another user.
+.SH "AUTHOR"
+.sp
+There are multiple \fBhardlink\fP implementations. The very first implementation is from Jakub Jelinek for Fedora distribution, this implementation has been used in util\-linux between versions v2.34 to v2.36. The current implementations is based on Debian version from Julian Andres Klode.
