Deep in a emac tutorial I discovered this hidden gem.

“percol adds flavor of interactive selection to the traditional pipe concept on UNIX.”

You can simply place it in the middle of a pipe and pick the options you want.

Example:

$ BUCKET="s3://cool-bucket" aws s3 ls $BUCKET | awk '{print $4}' | percol |sed "s;^;${BUCKET}/;" | xargs aws s3 rm
delete: ...
