BASH FOR loop using grep and awk

Question

I'm trying to get this script to cat a file and grep each line for 877 and for each line found, print the first column which is an IP and store it in hosts. It get stuck on awk every time. I run sh -x some.sh to see where it is hung up. Should I print to a file instead of a list? Why does it get stuck on awk?

hosts=()

FILENAME=/home/somethin/.hosts.conf

ips=`cat $FILENAME | grep -v '877'`

for line in $ips; do
     hosts=$(`awk '{print $1}'`)
done

echo $hosts

Answer 1

It can all be done using awk:

hosts=( $(awk '/877/{print $1}' $FILENAME) )

echo "${hosts[@]}"
