Get Root ID

With text output:-

OrgRoot=$(aws organizations list-roots --query 'Roots[0].Id' --output text)

Using JQ:-

OrgToot=$(aws organizations list-roots | jq -r .Roots.[0].Id)

OU_IDs=$(aws organizations describe-organization --query 'Organization.Id' --output text)  

#!/bin/bash
# Get the root of an Org and find the subordinate OUs in it.
 
ROOT_ID=$(aws organizations list-roots | jq -r .Roots.[0].Id)
printf "Root ID:- ${ROOT_ID}\n"
 
OUS=$(aws organizations list-organizational-units-for-parent --parent-id "${ROOT_ID}" | jq -c .OrganizationalUnits.[].Id)
printf "OUs:- ${OUS}\n\n"

Seearch for an OU by name:-

SpecificOU=$(aws organizations list-organizational-units-for-parent \
    --parent-id $RootId \
    --query 'OrganizationalUnits[?Name==`SpecificOU`].Id' --output text )

ACCOUNTS_RAW=$(aws organizations list-accounts --query 'Accounts[*].[Id]' --output json | jq -c .[][] | tr -d '\n')
ACCOUNTS="${ACCOUNTS_RAW//\"/ }"
 
echo "accounts_raw:- ${ACCOUNTS_RAW}"
echo "accounts is:- $ACCOUNTS"
 
for ACCOUNT in $ACCOUNTS
do 
       echo "Account is >${ACCOUNT}<"
       echo "do some work on each account"
done

Sometimes you may want to point to an account, but not reveal the full account number, this code will truncate your account to a specified length.

$ cat truncate.py
#!/usr/bin/python3
 
account = '123456784321'
removechar = 6
 
result1 = account[removechar:]
result2 = account[removechar:len(account)]
print(result1, result2)
 
$ ./truncate.py
784321 784321
