Hello! I've noticed something unusual when checking this PR:

• The page pages.es/common/alr.md has a more info link that does not match the one in the English page. Please check the "More information:" translation as well using https://github.com/tldr-pages/tldr/blob/main/contributing-guides/translation-templates/more-info-link.md.

Is this intended? If so, just ignore this comment. Otherwise, please double-check the commits.

I just rebased the branch so it stayed on top of main's HEAD, but ok, I won't do it again.

It's nice to know what edits were made after what comments. If you want to update a branch, use the buttons that appear in the github UI.

I did use them, I selected the "Update with rebase" option.

[Managor]

Ah, I see. I meant that Update Branch button that appears below the comment section here if the branch is outdated. I did't know other types existed.

As I said earlier, this is not the correct syntax.

Oh, I see it now. The other review confused me... So, as they're compulsory "enumerated" options (you have to select one or the other, but not both), you have to use the {{one|other}} format, right?

[Managor]

Correct. {{[-h|--help]}} is sort of an extention of that. Programs have shortform and longform options that do the same exact thing. The [ ] inside tell the client that they can display either of these and the command is the same.

Thanks for your contribution!

I don't know why the license/cla action is taking so long... the other times it ran it finished with no problems...
