$ and " if this should be a quoted
substitution.var=$"(whoami)"var="$(whoami)"ShellCheck has found a $"( or $"{ . This is
most likely due to flipping the dollar-sign and double quote:
echo $"(cmd)" # Supposed to be "$(cmd)"
echo $"{var}" # Supposed to be "${var}"
Instead of quoted substitutions, these will be interpreted as
localized string resources ($"..") containing literal
parentheses or curly braces. If this was not intentional, you should
flip the " and $ like in the example.
If you intentionally wanted a localized string literal
$".." that starts with ( or {,
either ignore this error or start it with a
different character.
