ShellCheck plugin for SonarQube
The newest version!
Parameter expansion starts with unexpected quotes. Double check syntax.
Problematic code
echo ${"Hello World"}
Correct code
echo $"Hello World"
Rationale
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.
Exceptions
