init command question
 

Hi team,
I have a question,I found that the permission of "/sbin/init "is 755,but why can not I run this command with the general user？

well you can literally run it, but the code will check your uid and only permit any consequences to be taken by root.

The permissions for the command is indeed rwxr-xr-x (755). But, though the command can be initiated by user, it will be executed as root. That is a limitation of that command, but an intentional limitation so that the user will not accidentally harm the system.

Acid_kewpie/matrix13 Thanks a lot!
So you mean the running mechanism or verification rules has been written in the program.Because I found that the file "/sbin/init" is a compiled executable program.Is that right?


Best regards.
