+## Use 'elif' instead of 'else if'.
+
+### Problematic code:
+
+```sh
+if [ "$#" -eq 0 ]
+then
+  echo "Usage: ..."
+else if [ "$#" -lt 2 ]
+then
+  echo "Missing operand"
+fi
+  
+```
+
+### Correct code:
+
+```sh
+if [ "$#" -eq 0 ]
+then
+  echo "Usage: ..."
+elif [ "$#" -lt 2 ]
+then
+  echo "Missing operand"
+fi
+```
+### Rationale:
+
+Many languages allow alternate branches with `else if`, but `sh` is not one of them. Use `elif` instead.
+
+### Exceptions:
+
+`else if` is a valid (though confusing) way of nesting an `if` statement in a parent's `else`. If this is your intention, please use canonical formatting and put a linefeed between `else` and `if`. 
+
+```sh
+
+if x
+then
+  echo "x"
+else     # line break here
+  if y
+  then
+    echo "y"
+   fi 
+fi
+```
