How can I add an IP address in a AWS CLI with out exporting

I am running below command to ingress in was-cli, it is working fine if I provide IP address, but I want it to know IP and pass it.
I was trying something like below but it is not helping

aws-cli
cidr
curl
doi
echo
http
https
ping
protoc
security
tcp
uri
url

aws ec2 authorize-security-group-ingress --group-id sg-123456778 --protocol tcp --port 22 --cidr echo "$(curl https://checkip.amazonaws.com)/32" --profile xyzzy

If I am doing below then it work but I want it to be done by above way.

IP=`echo "$(curl https://checkip.amazonaws.com)/32"`
aws ec2 authorize-security-group-ingress --group-id sg-123456778 --protocol tcp --port 22 --cidr $IP --profile xyzzy

>Solution :

Use -s with curl.

Try this:

aws ec2 authorize-security-group-ingress --group-id sg-123456778 --protocol tcp --port 22 --cidr $(echo "$(curl -s https://checkip.amazonaws.com)/32") --profile xyzzy
