As previously mentioned the # character is a symbol utilized by the shell to start a line of comment (or a string inside a line that will be ignored by the shell). In some cases, text books use it as the root's command prompt. For example, instead of writing:
└─• echo hello world
which is my prompt, I could write
this means you have to ignore the # characters, but it means you have to run the command as root. You could find also a $ sign: in this case the author is telling you to run the command as normal user:
again you have to ignore the $ sign and type only the command.
