1) :%s changes every line, :$s only changes the last line in the file.
2) $ is end of line rather than new line. ctrl+v ctrl+m is carriage return/line break character.
3) You can include /g if you want, makes no difference to this particular command, since there will be only one end of line marker in each line.
4) Use the “\” character to escape out special vi characters. So this command would change all $ symbols to c:
:%s/\$/c/g

Andrew.

1) Difference between :%s and :$s
:%s/$/ctrl+v ctrl+m – After every instance of $ (end line), insert ctrl+v ctrl+m (new line)?
:$s/$/ctrl+v ctrl+m – Replace every instance of $ (end line) with ctrl+v ctrl+m (new line)
Is the above correct?

2) Why use ctrl+v ctrl+m
Why doesn’t :%s/$/$/g work? This should mean that append after every $ (new line) another $ (new line)?
Why should ctrl+v ctrl+m and not another $ – eg, after every instance of an end-line, put another end-line, something analogous to
if (s[i]==’\n’) s[i+1]=’\n’;

3) Why not use /g?
Why don’t we use the /g after :%s/$/ctrl+v ctrl+m? Doesn’t it tell the command to do it for every occurrence of $ (end-line)?

4) Escape sequences
If I want to replace the character $ (dollar) by c (cents), is there some escape sequence I can use so that vim doesn’t mistakenly hunt for end-of-line characters instead of the ‘$’ character?

Thanks

How does one insert a new line?

For instance, if my file is -
test 1
test 2
test 3

and I want to make it,
test 1

test 2

test 3

Will a simple ‘:s/test/\n test’ work?

Been an Oracle DBA for most than 15 years but only recently I’ve decided to web logging some Oracle stuff.

I would appreciate your input on the site and if you want to contribute feel free.

Thanks.
