+## Don't use ls | grep. Use a glob or a for loop with a condition to allow non-alphanumeric filenames.
+
+### Problematic code:
+
+```sh
+ls /directory | grep target_file_pattern
+```
+
+### Correct code:
+
+```sh
+ls /directory/target_file_pattern
+```
+### Rationale:
+
+Matching non-alphanumeric characters with grep may require escaping.  Typically it is cleaner to use the built in pattern matching or another command like `find`
+
+### Exceptions:
+
+None
