    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 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。
