+## You need a space before the if single then "]" else "]]"
+
+### Problematic code:
+
+```
+if [ "$STUFF" = ""]; then
+```
+
+### Correct code:
+
+```
+if [ "$STUFF" = "" ]; then
+```
+
+### Rationale:
+Bourne shells are very whitespace sensitive. Adding or removing spaces can drastically alter the meaning of a script. In these cases, ShellCheck has noticed that you're missing a space at the position indicated.
+
+### Exceptions
+none.
+
+### Ignore
+```
+# shellcheck disable=SC1020
+if [ "$STUFF" = ""]; then
