Section Number and Name: 
6.1. Creating a Host Group

Describe the issue:
Only useful if a customer wants a single Environment 
If ran as is Parent_ID and HgID can provide multiple ids and the script is not in a loop  so it fails with to many variables 

Suggestions for improvement: 
Verify correct variables are in /root/.bashrc or add them into script
ARCH=
DOMAIN=
PROXYID=
NETNAME=
CAID=
MEDID=
ORGID=
LOCID=
OSID=
PARTTABLEID=

source /root/.bashrc

Set variables for loop

ENVIROMENT=$(hammer environment list |awk -F "|" {'print $2'}|grep -v -|grep -v NAME |sed 's/ //g' |grep -v production)
LEL=$(hammer lifecycle-environment list --organization $ORG |awk -F "|" {'print $2'}|grep -v - |grep -v NAME)

for loop to add hostgroups
for i in $ENVIROMENT; do for j in $(hammer --csv environment list |awk -F "," {'print $2'}| awk -F "_" {'print $3'}); do hammer hostgroup create --name rhel-7-"$j" --environment "$i" --architecture "$ARCH" --domain "$DOMAIN" --subnet "$NETNAME" --puppet-proxy-id "$PROXYID" --puppet-ca-proxy-id "$CAID" --medium-id "$MEDID" --organization-ids "$ORGID" --location-ids "$LOCID" --operatingsystem-id "$OSID" --partition-table-id $PARTTABLEID ; done; done
