Set Immutable Attribute

If you don’t want a file edited or deleted, you can set the immutable attribute to ON. If activated, not even root or the owner of the file can delete it. Users with write access can still read it, but they obviously will not be able to modify it. To unset it, just use the -i option.

# Set immutable attribute
sudo chattr +i text.txt
 
# Unset immutable attribute
sudo chattr -i text.txt

# Set immutable attribute sudo chattr +i text.txt # Unset immutable attribute sudo chattr -i text.txt

About Me

I'm Ulysses, a Cloud Engineer at Cardinal Health based in Columbus, Ohio. I’m a certified AWS Solutions Architect. This website is my way of documenting the things I have learned in the Cloud. When off the grid, I enjoy riding my electric skateboard. I have surfed, snowboarded and played the saxophone in the past. I hope you will find this site helpful. It's powered by WordPress and hosted in AWS LightSail.
