+## Remove spaces between # and ! in the shebang.
+
+### Problematic code:
+
+```sh
+# !/bin/sh
+echo "Hello World"
+```
+
+### Correct code:
+
+```sh
+#!/bin/sh
+echo "Hello World"
+```
+### Rationale:
+
+The script has spaces between the `#` and `!` in the shebang. This is not valid.
+
+Remove the spaces so the OS can correctly recognize the file as a script.
+
+### Exceptions:
+
+None.
