Parse sina UIDs from image link and generate a batch follow link.

get-follow-link.sh

#!/bin/bash

template="http://widget.weibo.com/relationship/bulkfollow.php?language=zh_cn&uids="
uids=`curl -s $1 | grep -oP '(?<=http://...\.sinaimg.cn/)\d*(?=/)' | xargs echo -n | tr ' ' ','`
url="$template$uids"
echo $url

Usage: ./get-follow-link.sh {URL}

It seems this method does not prompt captcha. We can use it for batch following.

The current limit is 20.

We need to divide the UIDs into several groups, each 20 users.
