How to write a BASH script that saves into a file yum package updates names

How can I get a list of packages available for update on RedHat (using yum) and put the package list in a file for later use?

Basically I would like to be able to remove from the list a few names with a BASH script and then perform a yum update using the updated list.

I knew about yum list available but I couldn't understand why awk was not printing the 1st column.

I have now fixed it:
yum list available | awk '(NR >=4) {print $1;}' | sed s/\.[^\.]*$//
