+## Aliases can't use positional parameters. Use a function.
+
+### Problematic code:
+
+    alias archive='mv "$@" /backup'
+
+### Correct code:
+
+    archive() { mv "$@" /backup; }
+    
+
+### Rationale:
+
+Aliases just substitute the start of a command with something else. They therefore can't use positional parameters, such as `$1`. Rewrite your alias as a function.
+
+### Contraindications
+
+None.
