Let's Encrypt on a Big-IP

When using the script create-profiles.sh I receive errors because I use to deactivate domains or fqdn-entries in the domain.txt file How could I modify the create-profiles.sh to ignore lines beginning with a ?

!/bin/bash
for i in $( cat domains.txt | awk '{ print $1}' ); do
  tmsh create ltm profile client-ssl auto_$i
  echo "Created  auto_$i client-ssl profile"
done
