Question 5

cd to the directory called final that is located within my home directory.

When you more the file called blink, you get the error message:

blink: Too many levels of symbolic links

A. What is it that is causing this error...specifically?

The link called blink does not exist.

The link called blink is linked to a very large file.

Too many symbolic links.

The link called blink is a link to alink. The link called alink is a link back to blink.

The file called blink should be called beelink.

Question 6

cd to the root directory. Execute the following command:

ls -ld /tmp

You will notice that the permissions on the /tmp directory contain the sticky bit. (The permissions end with a t)

A. What is the significance of the sticky bit being set on a directory?

(Hint: see the man page for the chmod command for more info on the sticky bit)

The sticky bit prevents a file from being deleted....forever.

A file can only be deleted or modifed by the user if owned by the user or can be deleted or modified by a privileged user.

The sticky bit prevents a file from being copied.

The sticky bit makes the file an executable file.

Question 7

You need to locate the PID of a process in the process table so that the process can be killed. On the UML system, construct a command string that will locate ONLY the PID of the process called init (/sbin/init).

The output of your command string should be a single number which is the PID of the init process.

Replace the ## to complete the comand string. The comand string must generate the output described above.

ps -ef | grep init | grep -v \'grep\' | awk \'{ print ## }\'

Question 8

cd to the directory called final that is located within my home directory.
When you cat the file entry called sga, you get the error message:

cat: sga: No such file or directory

What is it that is causing this error?

sga is a link.

sga is a link to file that does not exist.

sga does not exist in my directory called final.

The permissions on sga do not allow you to read the file.

Consider the following alias:

alias dirc=\'ls -l | grep \'^d\' | wc -l\'

Create the following alias.

alias gohome=\'cd $home\'

Upon executing the alias called gohome, you will....

Change directory to your own home directory.
