I found on an article a line that was saying: Now execute -> sudo chmod 700 !$

What does !$ in that case?

This is not a chmod parameter. See the Bash Manual:

!!:$ designates the last argument of the preceding command. This may be shortened to !$

So just look at the last command to figure out what you'd chmod.
