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
    %
