Re: Stripping characters from strings

[moen]

You could do something like
s/.$//g;
This means: substitute(s/) any one character(.) counting from the end ($) with nothing (//) and at all possible matches(g).

[elwarren]

Is the g needed in this case? Wouldn't this only match the end of line once?

[extremely]

With an anchor that isn't within an alteration, "g" is pretty useless. I'm not near a perl with Debugging turned on so I can't tell you if it's a no-op, but I do know it isn't a dangerous thing to have on there, just useless. =)

Update... And what merlyn said below. (yeesh $*)

--
$you = new YOU;
honk() if $you->love(perl)

[merlyn]

Actually, if $* is 1, then $ matches any embedded newline as well as the end of the string, so s/.$//g; actually makes sense!

I doubt that was the case here, though. {grin}
