I just need to restart tor service at startup the script is simple as that :
#!/bin/bash
sudo service tor restart
But I want to execute it without taking my password at every startup.
I followed these posts : https://askubuntu.com/questions/425754/how-do-i-run-a-sudo-command-inside-a-script/425990
and I changed my sudoers file with this :
username ALL=(ALL) NOPASSWD: /path/to/script
But as I try to execute it in terminal, the script always ask me for password.
I also try the others answers in this post but as that post as no validation I didn't find a solution. If someone have a solution ?

What operating system are you using? If Linux, what distribution? If this needs to be run at startup, why don't you just set the tor service to start on boot?

Please edit your question and clarify what you need. Do you just want tor to be started every time the machine reboots?

@terdon I find an answer and I think the question can help the community. The reason why I ask this question is minor and I think touch less people. And I learned things :)

OK, but the answer you got is really not a good way of starting a service at boot, if that's what you want. It means any user on the system will be able to restart tor with no password. For a cleaner way, see How to write startup script for systemd

Thanks, that's a good point. I use service tor withFoxyProxyinFirefox. For a reason I don't know I need to restartservice torif I want to load pages withFoxyProxyenabled by default. But if I understand the answer, myservice torstart one time and just after restart with my username and just allowed forservice tor. This could be another post.

The line
username ALL=(ALL) NOPASSWD: /path/to/script
gives username the right to run the script with sudo, as in
$ sudo /path/to/script
If you want the user to be able to restart tor specifically, with sudo in the script, use
username ALL=(ALL) NOPASSWD: /usr/sbin/service tor restart
Now the script may do
sudo /usr/sbin/service tor restart
Note that this command has to correspond exactly to the sudo configuration.

Yes, that is the right answer now it load without asking the password :) I have a last interrogation : is it safe to do that ?

This way works perfectly for my intention, but I'm also asking myself about security issue that could happened as terdon says
