Pattern: Parameter expansion starts with unexpected quotes
Issue: -
ShellCheck found a parameter expansion ${...} that contains an unexpected syntax element, such as single or double quotes.
In the example, this was due to wrapping a translated string $".." with curly braces, which is not valid.
It is unclear what the intention is with invalid expansions like ${'foo'}, ${$"foo"}, so please look up how to do what you were trying to do.
Example of incorrect code:
echo ${"Hello World"}Example of correct code:
echo $"Hello World"
