finding links to a file

I am writing a shell script that needs to files that are links to on specific shell script.

e.g.

/usr/bin/a.sh

/home/mydir/a.sh --> /usr/bin/a.sh
/home/yourdir/a.sh --> /usr/bin/a.sh
/home/hisdir/a.sh --> /usr/bin/a.sh
/home/herdir/a.sh --> /usr/bin/a.sh

I know I can set myself at the /home and "find" the links, but my question is more to the guru types. Is there a simple command that I can use on /usr/bin/a.sh to get the list of all the files that have links to it?
It might give output like:

# lnk2file /usr/bin/a.sh
/home/mydir/a.sh
/home/yourdir/a.sh
/home/hisdir/a.sh
/home/herdir/a.sh
#

Just want to know if there is a better way to skin this cat.

TIA

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
