AWS Cli calls in bash script variable assignment when sending parent-id/child-id

Question

My script needs to get OU parent for an account, Please note I do have a working bash script, with tilde quotes on aws cli commands only when being assigned to a variable, that is exactly same, but for --parentid/--child-id parameters shell check is not needed hence

When I run corresponding aws cli on terminal, it works fine , I have

```
aws organizations list-parents --child-id <acctid input> --query Parents[*].Id --output text
```

However when I use same in bash as below it does not assign the value, process nulls out. bash script has

```

    for account in $(aws organizations list-accounts --query 'Accounts[].Id' --output text); do
       echo $account
       parent_ou=`aws organizations list-parents --child-id $account --query Parents[*].Id --output text`
    echo $parent_ou
```

The only addition from working script is the assignment of parent_ou

Note it does print account correctly, so its only the parent_ou assignment not working. Have a similar problem with another, that works on terminal but not within bash, note mocked parent_id

```
  b_ous = `aws organizations list-organization-units-for-parent --parent-id o_hhhhh_**** --query OrganizationalUnits[*].Id --output text`
```

The error is

```
 command "o_hhhhh_****" not found
```

I have tried using variable instead of hardcode value, its same error.

Any idea what maybe wrong with these variable assignments in bash?

Thanks in advance

This worked for me

for account in $(aws organizations list-accounts --query 'Accounts[].Id' --output text); do
  echo "$account"
  parent_ou=$(aws organizations list-parents --child-id "$account" --query Parents[*].Id --output text | tr -d '\n')
  echo "$parent_ou"
done

I had to put the cli command for parent_ou as above, in $();
