# sort file inline

We can sort file by using `sort` command for example:

```bash
$ sort a.txt

# or

$ cat a.txt | sort
```

But this will only output to stdout. Some time you want the file to be sorted. Instead you can do

```bash
$ sort a.txt -o a.txt
```

note that this DOEST work and it will TRUNCATE the file

```bash
$ sort a.txt > a.txt
```
