Tip...

Use global replacement in its interactive mode to avoid making changes that you don't intend. To do this add the c option to the end of the global replacement command:

   :g/pattern1/s//pattern2/gc

vi will display the first occurrence of pattern1.

To replace it with pattern2 you must enter y (yes) and press <RETURN>.

If you don't want to replace this pattern press <RETURN> to go to the next occurence.
