It is a common practice in a lot of Unix books to indicate with $ a command 
line for the normale user and with # the command line for the super user. The 
fact that ubuntu suggests sudo is not relevant here, I use always the root 
account. The real problem here is that $ usually means the prompt of a 
normale user, while # not.

Surely it could be detailed to run sudo or a root shell, but as I wrote above, 
I think it's a common practice to use # before a single command line to 
indicate to run it as root. Moreover we are talking of the /proc filesystem 
here, and I don't see any way of confusing the user that should manipulate 
such file system.
