echo "myScript,hello word~~~" >>/home/myScript.txt

exit 0

Next, we add executable attribute to myScript

• chmod + x myScript

Then add the boot project

　　"Stool series"

• update-rc.d myScript defaults

 

Delete boot project

• update-rc.d -f myScript remove

note

/ Etc / init system is started

/etc/init.d application is started

/etc/rc*.d This is the start level, meaning please consult the specific level Linux boot level

update-rc.d this command is to configure /etc/init.d/ join these levels.

Of course, there are other ways to start, the first will be this kind of bar.
