之前使用阿里云日志服务，按照文档安装了ilogtail。后面不需要了，却找不到卸载文档。
仔细查看ilogtail的安装脚本后，发现里面有卸载方法。

wget http://logtail-release-cn-hangzhou.oss-cn-hangzhou.aliyuncs.com/linux64/logtail.sh -O logtail.sh;chmod 755 logtail.sh
./logtail.sh uninstall

正常卸载的反馈结果如下：

logtail.sh version: 1.3.0

./logtail.sh: line 529: lsb_release: command not found
