A question on .exrc while using vi

[Neil Greene]

Use the change command from within vi at the command prompt:

:[x,y]s/<p>/<r>/<f>


In the above example 

1) [x,y] are optional and may be replaced with line number
values to restrict the range of the change command.

2) p is the pattern you are changing

3) r is the pattern you want to change to 

4) f are optional flags of either 'g' for global change or 'c' for confirm on
each occurance.
