#print
Normally the 's' command only changes
the first instance on a line of the expression
it is looking for. Sometimes you want to change
more than one instance. If you put a 'g' after the
command, as in
s/cat/dog/g
all instances of 'cat' will be changed to 'dog'. To
print the result you must say
s/cat/dog/gp
('pg' at the end doesn't work, sorry).
Edit file 'stuff' in this directory to change every
instance of 'green' to 'red' on every line.
Then rewrite the file and type "ready".
