This isn't an R question, but a linux question.

Open a new terminal window:
The directions you are following tell you how to do that for the
Ubuntu linux being used, right at the beginning:

Open up a terminal (Applications->Accessories-> Terminal from the the toolbar)

As for your command, the $ is a prompt. You don't type that. Start with ls

What should you do now? Read a little bit about using linux command line tools


​Well, this being the R language forum, perhaps you should enter "R" after the 
command prompt?
Seriously, what do you want to accomplish? Since you are using Ubuntu, I will 
assume that you are using the default shell program, BASH. There is a BASH 
forum you could join called mailto:help-b...@gnu.org . It's easiest to sign up 
here: https://lists.gnu.org/mailman/listinfo/help-bashThis site has some nice 
articles about BASH and programming (scripting) using it: 
http://wiki.bash-hackers.org/BASH for beginners: 
http://www.tldp.org/LDP/Bash-Beginners-Guide/html/Since you seem to be using 
Ubuntu: https://help.ubuntu.com/community/Beginners/BashScripting
There are _TONS_ of commands installed in Ubuntu by default. Most of them have 
manual (man) pages. Most of the defaults are in the directory /usr/bin. You can 
list them simply by entering the command: "ls /usr/bin". My system has over 
6,500 programs stuffed in there. If you see something interesting, you can get 
some basic documentation on it by using the command: "man <cmd-name>". We've 
mentioned "ls", which lists the contents of a directory. If you want to know 
more, try "man ls". In addition to "man" there is a much more powerful 
information source called "info". Just use it instead of "man" as the command 
name. That is, use "info ls" to get some real detailed information on the ls 
command.
Another interesting command is "apropos". Think of it as being similar to the R 
systems' double question mark search. As an example, suppose you want to find 
out what commands might be helpful with a "zip" file. Enter the command: 
"apropos zip". On my system, I get a (truncated) response such as:
bunzip2 (1)          - a block-sorting file compressor, v1.0.6bzip2 (1)         
   - a block-sorting file compressor, v1.0.6
bzip2recover (1)     - recovers data from damaged bzip2 filesbzless (1)         
  - file perusal filter for crt viewing of bzip2 compressed textdecode (n)      
     - Access to zip archives
encode (n)           - Generation of zip archives
funzip (1)           - filter for extracting from a ZIP archive in a pipegunzip 
(1)           - compress or expand files
gzip (1)             - compress or expand filesIO::Compress::Bzip2 (3pm) - 
Write bzip2 files/buffers
IO::Compress::Zip (3pm) - Write zip files/buffers
IO::Uncompress::Unzip (3pm) - Read zip files/buffers
unzip (1)            - list, test and extract compressed files in a ZIP archive
unzipsfx (1)         - self-extracting stub for prepending to ZIP 
archiveszforce (1)           - force a '.gz' extension on all gzip fileszip (1) 
             - package and compress (archive) fileszipcloak (1)         - 
encrypt entries in a zipfile
Note the number in the parentheses after the command. A "1" indicates this is a 
normal command. Something which starts with a "3" (like 3pm) means this is like 
a subroutine package (The "pm" in 3pm means "Perl Module" - like an R package, 
sort of). Also note that some of the entries have nothing to do with a normal 
"zip" file; such as the entires with bzip2 in them - bzip2 is an alternative 
compressor program).

I'm fairly good with BASH, having programmed for over 3 decades, and used BASH 
for about 10 years. Which is both good and bad. The good is that I understand 
BASH fairly well. The bad is that I like "tricky coding" (a personal problem).
