SC1078

Did you forget to close this double quoted string?

Problematic code:

greeting="hello
target="world"

Correct code:

greeting="hello"
target="world"

Rationale:

The first line is missing a quote.

ShellCheck warns when it detects multi-line double quoted, single quoted or backticked strings when the character that follows it looks out of place.

Contraindications

If you do want a multiline variable, just make sure the character after it is a quote, space or line feed.

var='multiline
'value

is more readable and won't produce a warning as:

var='multiline
value'
