## Use `find -print0` or `find -exec` to better handle non-alphanumeric filenames.
### Problematic code:
```sh
ls | xargs wc -w
```
### Correct code:
```sh
find . -maxdepth 1 -print0 | xargs -0 wc -w
```
```sh
find . -maxdepth 1 -print0 -exec wc -w
```
### Rationale:
Using `-print0` separates each output with a NUL character, rather than a newline, which is safer to pipe into `xargs`. Alternatively using `-exec` avoids the problem of piping and parsing filenames in the first place.
See [[SC2012]] for more details on this issue.
