If you have a file that you want nobody can change it, you shall type the following command into a shell
# sudo chattr +i filename
You can check the attributes using the following command:
# lsattr
----i------------- ./gg1.txt
Now also the root user cannot delete the file, if the root user want to change/delete this file he shall reset the file attributes as follows:
# sudo chattr -i filename
You can check the attributes using the following command:
# lsattr
------------------ ./gg1.txt
