Using Special Characters in Scripts
The dollar sign ($) character and quote (") characters have special purposes in scripts.
The ($) indicates a variable, and the (") surrounds text strings. To use
these characters as regular characters, precede the special character with a backslash
character (\). For example:
set var variablename \$<varname>
set var $CLI.USER “Robert \"Bob\" Smith”
Scripts also support quote characters within quotes.
