You can also use Visual Mode if you don't want to count lines :
Press [Esc] key
Use arrows to move cursor to the beginning of your paragraph
Press [v] to enter Visual Mode
Use arrows to select all the lines you want to comment
Then type the following command :
:'<,'>s/^/#/g
Note : when you hit ':' in Visual Mode, ":'<,'>" is added automatically.

'|' can be used to separate commands, so you can give multiple commands in one line. If you want to use '|' in an argument, precede it with '\'.
:4,8 s/^/#/ | 12,20 s/^/#/Instead of counting lines ( using: .,+N ) one could also use a search ( .,/WORDONTHELASTLINE/ ),
so
this is line 1
this is line 2
this is line three
this is line 4
could be commented by putting the cursor on line 1 and using:
.,/three/ s/^/#/g
Using
#if 0
Lines to be commented
#endif
is much easier....
To comment out multiple lines while writing scripts under vi where "#" is the comment marker.
Where "N" is number of lines to be commented after the current cursor location inclusive of the current line.

To remove comment, same procedure but :
:'<,'>s/^#//gThank you!
