ifconfig down using ifconfig output

Question

On RH 6.7, using bash:

I need to free up some IP addresses using a script.

I am looking for a way to shutdown the bonding using the ifconfig xxx down command.

I search for list of candidate using this:

$ ifconfig |grep ^bond[0-9]:[1-9] |awk '{print $1}'

How may I easily use the output from this command to the down command?

xargs did not work for me:

$ ifconfig |grep ^bond[0-9]:[1-9] |awk '{print \$1}' | xargs -n 1 ifconfig  down

Thanks

Found a nice option:

for i in `ifconfig |grep ^bond[0-9]:[1-9] |awk '{print $1}'` ;   do 
  ifconfig $i down;
done
