在国外的VPS上（我的是韩国节点）运行此脚本，会提示如下错误
[root@localhost ~]# ./sshbl_deny.sh

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
cat: zhangnq_sshbl_deny.txt: No such file or directory

之后采用wget方式单独运行curl一步发现网址会进行重定向如下
[root@localhost ~]# wget http://www.chekiang.info/scan/html/zhangnq_sshbl_deny.tar.gz

后在脚本中对curl加入-L参数后，脚本运行正常
