Check API for existence of a user - TrueNAS-SCALE-22.12.2

[bothunbr]

Hello Everyone,

Is there a simple way to check if a local username exists with the TNScale API? The way I'm doing now is overly complicated. I'm calling /user and looping thru all usernames.

The goal is to check to see if a username already exists in the system before calling userPost as there are several tasks that need to be be done before I actually create the user.

I'm sure there is a very simple solution that I'm missing.

Thanks in advance for any assistance you can provide.

midclt call user.query | jq -r '.[]|.username|select(. == "<username to match>")'

Returns the matching username if it already exists, or an empty string if not.

There's also the old reliable finger -m -p <username to match>.

Samuel,

Thank you for the ultra fast response and thank the internet for people like you!

I found a much easier way to query username thru the API. I really shouldn't have spent hours figuring this out as it was so simple.

/api/v2.0/user?username=testuser2

Maybe this will help others.

Thanks again for your help!
