script!!!

hi guys!
i'm newbie and i've got a porblem here... i want to use a function instead of a command, such as using "a" to replace for "who" command ( except using "alias" ).. so i have this script

. ./a.sh
[root@ftp ~]# cat a.sh
#!/bin/bash
function a {
unset a
echo " $a=$(who) "
}

But the result is

a
=root :0 2012-11-28 08:36
root pts/1 2012-11-28 08:36 0.0)
