Are there any command line options available to know the (user)account type?

Actually, this is just a convenience available by default to search the machine accounts. Admins can create the users or group SamAccountname ending with dollar and make them to be part of Domain computers group.
Checking for $ or checking the primary group as “Domain computers” helps most of the scenarios. But it’s still not authoritative.

    The thing to check for is the '$' on a computers samaccountname, you
    can do it with wbinfo:
    root at dc3:~# wbinfo -i dc3
    failed to call wbcGetpwnam: WBC_ERR_DOMAIN_NOT_FOUND
    Could not get info for user dc3
    Okay user not found, so it either doesn't exist or is a computer
    root at dc3:~# wbinfo -i dc3$
    Yes, it's a computer.
    root at dc3:~# wbinfo -i rowland
    This appears to be a user
    root at dc3:~# wbinfo -i rowland$
    failed to call wbcGetpwnam: WBC_ERR_DOMAIN_NOT_FOUND
    Could not get info for user rowland$
    This proves it isn't a computer
