-.TH RELINK 1 "July 30, 1990"
-.AT 3
-.SH LINK
-relink \- relinks multiple symbolic links
-.SH SYNOPSIS
-.B relink perlexpr [symlinknames]
-.SH DESCRIPTION
-.I Relink
-relinks the symbolic links given according to the rule specified as the
-first argument.
-The argument is a Perl expression which is expected to modify the $_
-string in Perl for at least some of the names specified.
-For each symbolic link named on the command line, the Perl expression
-will be executed on the contents of the symbolic link with that name.
-If a given symbolic link's contents is not modified by the expression,
-it will not be changed.
-If a name given on the command line is not a symbolic link, it will be ignored.
-If no names are given on the command line, names will be read
-via standard input.
-.PP
-For example, to relink all symbolic links in the current directory
-pointing to somewhere in X11R3 so that they point to X11R4, you might say
-.nf
-
- relink 's/X11R3/X11R4/' *
-
-.fi
-To change all occurences of links in the system from /usr/spool to /var/spool,
-you'd say
-.nf
-
- find / -type l -print | relink 's#/usr/spool#/var/spool#'
-
-.fi
