SC1140

Unexpected parameters after condition. Missing &&/||, or bad expression?

Problematic code:

[ "$1" ] input="$1"

Correct code:

[ "$1" ] && input="$1"

Rationale:

ShellCheck found characters (other than redirections) after the ] or ]] in a test expression. This is not valid.

This sometimes happens when there was an additional expression or command, but joining || or && is missing. Alternatively, it could happen due to typos (like [[ $1 ]]] with an extra ]), or generally from malformed test expressions.

Exceptions:

None
