I add this line to visudo, in order to give full permissions to yael user:
yael ALL=(ALL) NOPASSWD: ALL
But when I want to update the /etc/hosts file, I get permission denied:
su – yael
echo "10.10.10.10 yael_host">>/etc/hosts
-bash: /etc/hosts: Permission denied
sudo echo "10.10.10.10 yael_host">>/etc/hosts
-bash: /etc/hosts: Permission denied
ls -ltr /etc/hosts
-rw-r--r--. 1 root root 185 Aug 7 09:29 /etc/hosts
How can I give to user yael ability like root?
The source of the problem is that the output redirection is done by the shell (user yael) and not by sudo echo.
In order to enforce that the writing to /etc/hosts will be done by user root instead of user yael - You can use the following format:
echo "10.10.10.10 yael_host" | sudo tee --append /etc/hosts
or
sudo sh -c "echo '10.10.10.10 yael_host'>>/etc/hosts"
