On the command line, which of the commands listed below would let you change the name of the file linux-security-guide to linux-security-guide-old in the current directory? Choose only one answer:

1. cp linux-security-guide linux-security-guide-old

2. mv linux-security-guide linux-security-guide-old

3. cn linux-security-guide linux-security-guide-old

4. chmod linux-security-guide to linux-security-guide-old

5. You cannot use file names with dashes ( - ) in them so none of the above commands is valid.

Answer later.

oooh, at last one I could take a stab at ...

 

So...take a stab. Or are you waiting for those "hide" tags Tomshawk mentioned that would conceal a member's answer from those who haven't answered yet?

 

OK, so I was rash ...

As far as I can tell, cp would let you copy the file or directory, but looking at the way you phrase the question, and from my experience of our Linux-based servers, chmod alters the permissions on the file to allow you to then rename it. I use chmod daily at work when customers have buggered up their directory permissions or need certain access for certain filetypes, etc.


So it has to be cn

But I know I'm going to crash and burn again as always here, Trip ...

 

Number 1 is my choice of answer.

 

linux doesnt have a rename command
you move the file from one location to the other, that includes the name not just the directory

2

 

Yeah, 2 for this one

 

Answer time: the correct answer is 2: mv linux-security-guide linux-security-guide-old.

As correctly pointed out, linux has no rename command. When you use the mv (move) command and move a file within the same directory using a different name, the name of the file changes. If you use this command specifying the name of a file that does exist, the first file (in this case "linux-security-guide") will be moved into the second file ("linux-security-guide-old").
