+.Nd return resolved physical path
+.Sh SYNOPSIS
+.Nm
+.Op Fl q
+.Op Ar path ...
+.Sh DESCRIPTION
+The
+.Nm
+utility uses the
+.Xr realpath 3
+function to resolve all symbolic links, extra
+.Ql /
+characters and references to
+.Pa /./
+and
+.Pa /../
+in
+.Ar path .
+If
+.Ar path
+is absent, the current working directory
+.Pq Sq Pa .\&
+is assumed.
+.Pp
+If
+.Fl q
+is specified, warnings will not be printed when
+.Xr realpath 3
+fails.
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+Show the physical path of the
+.Pa /dev/log
+directory silencing warnings if any:
+.Bd -literal -offset indent
+$ realpath -q /dev/log
+/var/run/log
