Check if a port is open to the internet using canyouseeme.org

cysm() { curl -sd port="$1" http://canyouseeme.org |grep -o 'Success\|Error' }
For now just returns either "Success" or "Error". My awk-fu isn't strong enough to hackily parse out the error in case there is one, so I kept it simple.
Sample Output
~ [email protected]
❯ cysm 80
Success

~ [email protected]
❯ cysm 443
Error

0
