How to sort this kind of file with “sort”

Question

I have this file I would like to sort with the order "sort" in linux (very beginner)

I tried sort without parameter, without success. I tried sort -n, without success.

Is it because there are a lot of "blanks" on each line to be sorted ?

How to sort this kind of file ?

EDIT :

I would like the result in the same file. that's perhaps why it does not work ?

example :

Answer 1

use sort -n -k 1.10,1.23 filename .

-n is a numeric sort. -k describes where the key is. Look at sorts man page. In my example I describe a key from columns 10-23. You may not need -n since it looks like all the characters are between 0-9.
