找到了一个奇怪的脚本看上去是定时任务，想办法还是得用pspy64，使用ssh私钥登录再使用wget上传就能使用了。。。。。pwncat-cs的雷点？？？

因为路径优先级是当前目录所以：

cd /tmp && find . -type f -user $(whoami) -name "*.$x" -exec rm {} +
可以进行劫持find命令！

--reference=RFILE
use RFILE's owner and group rather than specifying OWNER:GROUP values. RFILE is always dereferenced.
以一个文件的权限进行参考，改其他文件权限，相当于按照这个模板改权限。。。。。而文件又是传进去文件名执行的，所以我们的文件名就成了配置项，这思路。。。
