How to give sudo access to a bash script?
提问by ronnie
I have a bash script(chbr.sh) to change my display brightness from terminal as my brightness keys doesn't work.
我有一个 bash 脚本 ( chbr.sh) 来从终端更改我的显示亮度，因为我的亮度键不起作用。
`sudo setpci -s 00:02.0 F4.B=30`
Now, every time I run that script it asks for password which I don't like. So, I googled a little and found out that one can edit /etc/sudoersfile to disable the password feature.
现在，每次我运行该脚本时，它都会要求输入我不喜欢的密码。所以，我用谷歌搜索了一下，发现可以编辑/etc/sudoers文件以禁用密码功能。
So, I edited my sudoersfile with the below content
所以，我sudoers用以下内容编辑了我的文件
ronnie ALL = (ALL) NOPASSWD: /home/ronnie/chbr.sh
Now when I run my script as ./chbr.shit again asks for my password. So, is this not the right way to give sudo access to a bash script or what am I doing wrong here.
现在，当我运行我的脚本时，./chbr.sh它再次询问我的密码。那么，这不是让 sudo 访问 bash 脚本的正确方法，还是我在这里做错了什么。
ronnie@ronnie:~$ ls -l chbr.sh
~rwxrwxr-x 1 ronnie ronnie 46 Jul 13 15:59 /home/ronnie/chbr.sh

You make all correct, but execute the script with te full path:
你做的一切都正确，但用完整路径执行脚本：
$ sudo /home/ronnie/chbr.sh

Do you run sudo /home/ronnie/chbr.sh?
你跑sudo /home/ronnie/chbr.sh吗？
With the content of the file being
随着文件的内容
setpci -s 00:02.0 F4.B=30
Or you allow user ronnie to sudo setpciwithout password:
或者您允许用户 ronnie 在setpci没有密码的情况下执行 sudo ：
ronnie ALL = (ALL) NOPASSWD: /sbin/setpci<-- or whatever path your setpci resides in.
ronnie ALL = (ALL) NOPASSWD: /sbin/setpci<-- 或您的 setpci 所在的任何路径。
