## 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
