Start rsync automatically

1. Run the script/etc/init. d/

2. Authorization
Chmod + x rsync

3. If the binsh ^ M error is thrown, rewrite the code.
Set unified dos Encoding
(Please refer to the rsync script to throw binsh ^ M bad interpreter document)

4. Add to service
Chkconfig -- add ningx


5. Random start script to drive rsync startup
Chkconfig -- level 2345 rsync on

 

 

 

The following error was found during script execution:
/Bin/sh ^ M: bad interpreter: No file or directory

Error analysis:
Because the operating system is windows, the script I edited in windows may have invisible characters.
The script file is in DOS format, that is, the end of each row is identified by \ n \ r, and its ASCII code is 0x0D, 0x0A.

There are many ways to check whether the file is in DOS or UNIX or MAC format.

Solution:
Vim filename
Run the following command:
: Set ff? # You can see the dos or unix words. If it is in dos format.


Then use
: Set ff = unix # force it to unix format, and then save the disk and exit.
Run the script again.
