The Linux administrator is called the "root" user.
With most Unix-derived systems, "root" is the super-user account.
The root account is the administrative account on Linux; this account has control over everything in the system.
Unlike in MS Windows, where any user can alter, change, or damage the system, only a root user can make such changes with linux type systems. So it is an extra security measure.
su (will change user to root)sudo command (will run command as root)
unix and linux systems are true multi user (root + others) but in windows admin and main user are same !
"/" is the root directory in Linux. Make sure not to confuse this with the "/root" directory, which is the home directory for the user "root" (similar to "Administrator" on Windows)
Yes. It's controllable by standard users if not inhibited by the root user who happens to be the administrator.
The root directory is /. The home directory is /home/user.
Typically a root user sees the '#' symbol as their prompt. If they already have a prompt via the PS1 shell variable then the # symbol is usually added at the end to indicate that they are a root user in this current context.
Either login as the root user or type: sudo then the command you wish to run.
That would be /root, which is the home directory of the root user. Keep in mind, according to the Filesystem Hierarchy Standard, /root is actually optional, but I've never seen a Linux distribution that didn't have it anyway.
