onliner to extract params from url

oparam.sh

echo "https://www.example.com/?aaa=bbb&ccc=ddd" | tr '?' '&' | awk -F '&' '{for(i=2;i<=NF;i++){split($i,t,"=");print t[1]}}' 

while read u; do echo $u | tr '?' '&' | awk -F '&' '{for(i=2;i<=NF;i++){split($i,t,"=");print t[1]}}'; done < plainurls.txt | sort -fu

From wayback json file:
cat waybackurls.json|jq -r '.[]'|grep 'http'|cut -d '"' -f 2 | while read u; do echo $u | tr '?' '&' | awk -F '&' '{for(i=2;i<=NF;i++){split($i,t,"=");print t[1]}}'; done | sort -fu

function oparam {
  echo $1 | tr '?' '&' | awk -F '&' '{for(i=2;i<=NF;i++){split($i,t,"=");print t[1]}}' 
}
function oparamv {
  echo $1 | tr '?' '&' | awk -F '&' '{for(i=2;i<=NF;i++){split($i,t,"=");print t[2]}}' 
}
function oparams {
  while read u; do echo $u | tr '?' '&' | awk -F '&' '{for(i=2;i<=NF;i++){split($i,t,"=");print t[1]}}'; done < $1 | sort -fu
}
function oparamsv {
  while read u; do echo $u | tr '?' '&' | awk -F '&' '{for(i=2;i<=NF;i++){split($i,t,"=");print t[2]}}'; done < $1 | sort -fu
