Hi there!

Current deluser is in the pages/common/, which I don't understand, because it works a little bit different on different OSes 🤔

I added the correct version to pages/linux/, but dunno whether I should also delete old one in common

I know you guys are picky about language, so 1-2 example might need re-phrasing 😅

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

• The page linux/deluser.md already exists under the common platform.

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

Please fix the error(s) and push again.

Hello @TheLastGimbus, and thank you for the new page! I've left some comments below for you to review.

@TheLastGimbus I think common/deluser.md might actually be userdel (#175) which I believe is more low-level.

deluser.md and userdel.md should be in linux/ not common/ 🤔

Well, they're very old 😄 #175 is very old considering that this is PR #5245!

@TheLastGimbus Will you please:

1. Delete common/userdel.md
2. Rename common/deluser.md to linux/userdel.md
3. Add https://man7.org/linux/man-pages/man8/userdel.8.html as a "More information" link to linux/userdel.md

Sorry, I know that's a lot, but these are old pages and need a little cleanup.

Thank you!

Note: if you're committing locally, remember to run git pull to incorporate the changes made on GitHub into your local repo!

Note to maintainers: the deleted deluser pages was wrong, it shouldn't have been added. @rubenvereecken added it #175, but I think they confused it with userdel.

[TheLastGimbus]

Okay, everything resolved and cleaned up as you wished

I know you guys are picky about language

...but I do agree with that very much. Better finish it once for good than fix it 3 more times later 👍
