$ id -a test
uid=6236(test) gid=999(local) groups=999(local),9003(testadmin)

Above id -a i want to use use below command groupiD=999 & secondory_group=9003.

sudo /usr/sbin/useradd -u $userID -g $groupiD -G $secondory_group -c "$fullname" -m -d $HomeDirectory -s $shell $login

groupiD=$(id -a | tr ' ' '\n' | nawk -F"[(),=]" '/gid=/{print $2}')
secondary_group=$(id -a | tr ' ' '\n' | nawk -F"[(),]" '/groups=/{print $4}')

$ id -a kmanoh
uid=5573(kmanoh) gid=2022(dbaprod) groups=2022(dbaprod)
$

Above user not having secondary ID so we have to use 2022 is alone..

$ secondary_group=$(id -a | tr ' ' '\n' | nawk -F"[(),=]" '/groups=/ {if($0~/\,/){print $5}else{print $2}}')
