开机自动启动rsync
1. 扔脚本进去/etc/init.d/
2. 授权
chmod +x rsync
3. 一旦抛出:binsh^M错误就执行编码改写
设置dos统一编码
(请看rsync脚本抛出binsh^M bad interpreter文档)
4. 添加到服务
chkconfig --add ningx
5. 随机启动脚本带动rsync开机启动
chkconfig --level 2345 rsync on
执行脚本时发现如下错误：
/bin/sh^M: bad interpreter: 没有那个文件或目录
错误分析:
因为操作系统是windows，我在windows下编辑的脚本，所以有可能有不可见字符。
脚本文件是DOS格式的, 即每一行的行尾以\n\r来标识, 其ASCII码分别是0x0D, 0x0A.
可以有很多种办法看这个文件是DOS格式的还是UNIX格式的, 还是MAC格式的
解决方法：
vim filename
然后用命令
:set ff? #可以看到dos或unix的字样. 如果的确是dos格式的。
然后用
:set ff=unix #把它强制为unix格式的, 然后存盘退出。
再次运行脚本。
