You don't really need bash for this.
Here's a sample awk script that should work:
% cat -n /tmp/userlist.awk
1 #!/usr/bin/awk -f
2
3 {
4 print $1,"has uid",$2;
5 }
% chmod 0755 /tmp/userlist.awk
% cat /tmp/user-data
admin 100
admin2 200
admin3 300
admin4 400
% /tmp/userlist.awk < /tmp/user-data
admin has uid 100
admin2 has uid 200
admin3 has uid 300
admin4 has uid 400
%
