I have a .txt file with numbers ordered like this (on the same row):

```
106849_01373    106849_01967    106850_00082    23025.7_01059   

```

I would like to convert them like that:

```
106849_01373
106849_01967
106850_00082
23025.7_01059

```

I have no idea which command to use. Can somebody help me with this?
