224 You Are Here

Now that you’re starting to get the hang of changing directories, see what happens when you change

to root’s login directory.

cd /root

Oops... You’re not logged in as root, so you’re “denied permission” to access that directory.

Denying access to the root and other users’ accounts (or login directories)isonewayyourLinux

system prevents accidental or malicious tampering. You’ll ﬁnd out more about ﬁle “ownership” and

permissions later in this chapter.

Really want to change to the root login? Then you’ve got to use the su command. Type this series of

commands:

[billy@localhost billy]$ su root

Password: (your root password)

[root@localhost billy]# cd /root

[root@localhost /root]#

As soon as you give the root password, you’ll see the changes in your command prompt to show

your new, superuser status: the root account designation at the front of the prompt and # at the end

(as shown in Figure 16.4).

Figure 16.4: Becoming root

Now, when you cd to root’s login directory, you’ll be granted access.
