<character> "$" Common names: ITU-T: dollar sign. Rare:
currency symbol; buck; cash; string; escape (when used as the
echo of ASCII ESC); ding; cache; INTERCAL: big money.
Well-known uses of the dollar symbol in computing include as a
prefix on the names of string variables in BASIC,
shell and related languages like Perl. In shell languages
it is also used in positional parameters so "$1" is the
first parameter to a shell script, "$2" the second, etc.
