[Novalug] vi question

[Geoff McNamara]

Make sure you are in command mode with:
<esc><esc>

Then enter the command to change/substitute a character throughout the
whole file (every line) - globally (every occurrence within a line):
:%s/x/y/g

What that command means is:
: <-- starting a command
% <-- address range is the entire file
s <-- substitute
/x/y/ <-- (the delimiter here is "/" but any delimiter could be used)
      given the substitute command above change "x" for "y"
g <-- the global option which switches the command to substitute every
occurrence within a line (not just the first occurrence)

Enjoy,
