    The SUID bit is a type of permission files that is previously granted to a file. In Linux when you run a program, these special permissions are inherited to the user who is working. The SUID grants permissions to a user temporarily.

    Explanation:

    If the time lengthens, it is possibly due to a security breach. A change of the password is recommended, through the passwd command. Through this command, some files cannot be opened or seen by the user, only by the user who has root permissions. By configuring the passwd through the SUID we can grant root user permissions to any type of user, so that in such case update, use the shadow and files.
