+## You need a space before the #.
+
+### Problematic code:
+
+    while sleep 1
+    do# show time
+      date
+    done
+
+### Correct code:
+
+    while sleep 1
+    do # show time
+      date
+    done
+
+### Rationale:
+
+ShellCheck has noticed that you have a keyword immediately followed by a `#`. In order for the `#` to start a comment, it needs to come after a word boundary such as a space. 
+
+### Exceptions:
+
+None.
