Linux – Giving user read permissions everywhere (Linux)

backuplinuxpermissions

I have a "backup" user on my server that needs to have read permissions everywhere. Doing chown 444 -R / backup doesn't seem like the right thing to do, so what should I do?

You're mixing two commands:

  • chown that is used to change the owner of a file. Exemple: chown root:adm /etc/passwd

  • chmod that is used to change the permission of a file. Exemple: chmod g+r myfile

Whatever your goal is, you really don't want to have your backup user to own every file and you certainly don't want to have every users on your system the right to read every files of your system.

What is your goal?
