Don't use ls | grep. Use a glob or a for loop with a condition to allow non-alphanumeric filenames.

Problematic code:

ls /directory | grep target_file_pattern

Correct code:

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
