Detailed steps for Linux account file control management

Detailed steps for Linux account file control management

In the Linux system, in addition to various accounts manually created by users, there are also a large number of accounts generated during the system or program installation process. In addition to the super user root, a large number of other accounts are only used to maintain system operations, start or maintain service processes, and are generally not allowed to log in, so they are also called non-login users.

For user accounts that are not used for a long time on the Linux server, you can temporarily lock them. Account configuration information is stored in /etc/passwd and /etc/shadow. The chattr command can be used to manage accounts.

  • chattr +i locks the file
  • chattr -i unlocks the file

lsattr View file status
