LTM script modification

Do you really need

sed

 Create the node with a name instead of IP... 
tmsh create ltm node mytest address 4.4.4.4
 search all pools with IP 1.1.1.1 member and create the modify command line 
for OUTPUT in $(tmsh list ltm pool one-line | grep "ltm pool" | grep 1.1.1.1  | awk '{print $3}') 
> do
> echo modify ltm pool $OUTPUT members add { mytest:8004} members delete { 1.1.1.1:8004}
> done
