wp add user command does not allow a dash in username

• [x] Yes, I reviewed the contribution guidelines.
• [ ] Yes, more specifically, I reviewed the guidelines on how to write clear bug reports.

Describe the current, buggy behavior

Dashes aren't allowed in usernames, they are when using the wp-admin user creation form.

wp user create user-bob [email protected] --role=administrator
Error: Usernames can only contain lowercase letters (a-z) and numbers.

Describe how other contributors can replicate this bug

wp user create user-bob [email protected] --role=administrator

Describe what you expect as the correct outcome

A username with a dash should be possible.

I believe this is the wrong repo for this issue, go to this repo for this issue.

This is indeed a bug. I just tested, and everything works as expected when creating a user with a dash in the slug via the WP admin backend.

WP-CLI should allow for this as well.

I think this is working as expected.

On multi-sites, the rules for usernames are more restricted compared to single sites. I am able to create a username with hyphens on a single site setup.

However, on a multisite setup, I can see the error on the WP admin backend (see image below). The details shared by the OP indicate they're on a multi-site environment. (Path /www/elementormultisite_511/public)

See this further reference.

If using a dash or a space be sure to wrap the string in double quotes: wp user create "fname-lname" [email protected]

Like mentioned above https://github.com/wp-cli/entity-command/issues/300#issuecomment-1046235281 this is working as expected. In multisite - character is not accepted by core itself. For single installation, username with - could be passed wrapped with apostrophe like wp user create "fname-lname".
