Function Fatalf

cmd/utils/cmd.go:68–83

Fatalf formats a message to standard error and exits the program. The message is also printed to standard output if standard error is redirected to a different file.

(format string, args ...interface{})

// The message is also printed to standard output if standard error
// is redirected to a different file.

		// stdout is unlikely to get redirected though, so just print there.
