Hello,
The command
echo "${PATH//:/$'\n'}"
yields
/usr/bin'
'/bin'
'/usr/X11R6/bin
while
newline=$'\n'
echo "${PATH//:/$newline}"
yields
/usr/bin
/bin
/usr/X11R6/bin
Is this by intention?
$ bash --version
GNU bash, version 3.00.16(1)-release (i386-redhat-linux-gnu)

By the way, I wish a search for \$\' and \$\" in the man page would turn up
something for each.
Presently, I only get something for \$\". The hit is the description of the
"extquote" shopt option.
The form $"string" is described as:
A double-quoted string preceded by a dollar sign ($) will cause...
so you don't find it searching for $".
No single-quotes are searchable, because they are represented in the man page
with the utf byte sequence 342 200 231 octal. I know of no way to generate that
character with my keyboard. Even cut-n-paste does not work using gnome-terminal
and less.
The situation is slightly better under info, but there the single quotation
mark closes every quotation made by the info text itself. Fortunatly the
description of the $'string' form is among the first things that turn up when
searching for $' although there is a risk people will give up thinking there
will be a zillion places with the three character `$' mentioning the $
character.
Regards,
Enrique
