Which means
: go into ex mode
1,$ from line 1 to the last line in the file
s substitue the following pattern
/^/ The pattern is the beginning of the line
\#/ replace the first pattern with this one - a #
There are a number of other ways of doing it too, EG:
:g/^/s//\#/
You might need to escape the # with a \ because # is special to vi (it
means the name of the previous file we were editting in this current
