@mfilotto
Oh, buddy, sorry for the silence. Perhaps, you have another version sed or I made a bug. :)
Were you able to make the fix?

@mfilotto had the same problem, substituting "[^A-z]" with "[^a-zA-Z]" did the trick for me (Centos 7 sed 4.2.2).

$ curl -Ls https://gist.github.com/andkirby/54204328823febad9d34422427b1937b/raw/semversort.sh | bash

@leifhetle thanks for this note.
@Wolvverine, yeah, it doesn't work. But it works with this one:
https://gist.github.com/andkirby/0046df5cad44f86b670a102b7c8b7ba7/raw/version_sort_install.sh
Yeah, that's PHP function. Seems it's not what you are looking for.

Just tested sed original script on Ubuntu - it does work

# sed --version
sed (GNU sed) 4.4

How about just sort -V? :)

       -V, --version-sort
              natural sort of (version) numbers within text

@waja here is Stack Overflow thread:
It might help you find a proper solution which might work for you.

But in a nutshell, no, "sort -V" does not work (as initially I was needed to use -patch suffixes), you may see it in this answer.

This script produces wrong result.

Example:

$ (echo 0.5; echo 0.5.1; echo 0.5.2) | semversort.sh
0.5.1
0.5.2
0.5

@yurivict yes, it's not intended to use various formats, but only Semantic Versions format which is MAJOR.MINOR.PATCH.
Like it described in https://semver.org/
Thanks for this note anyway, it's good to know edge cases.
