QUser Command Examples

QUser Command – Get logged on user on the remote computer

quser /server:it-cor20

In the above QUser command, it takes the quser /server parameter to get logged-on user information about remote computer it-cor-20.

It returns the list of all the users currently logged on to the remote desktop machine and prints output on the console as below with logged-on username, sessionname, sessionid, state, logon time.

PS D:\LogTest> quser /server:it-cor20

 USERNAME  SESSIONNAME ID    STATE     IDLE TIME    LOGON TIME
 Tom       console     1    Active      None        27-07-2021 14:13

QUser command to get logged in user name on the remote computer

$users = quser /server:it-cor20
foreach($user in $users)
{
    $parsed_User = $user -split '\s+'
    #Get UserName
    Write-Host $Parsed_user[0]
}

In the above PowerShell QUser example, the Quser command gets the list of the logged-on user sessions to the remote computer.

Using the QUser /server command, it takes the remote hostname and gets the logged-on user sessions to the $users variable.

We then iterate over the $users object using the foreach to split the user object string to get a username and assign it to the $parsed_User. Then, we use Write-Host command to print and view logged-on users onto a remote computer.

QUser logoff or disconnect user

Using the PowerShell quser logoff command, you can log off any user with the session ID or session name that you get using the quser command

logoff 15 /server:it-cor20

In the above command, the quser log-off command disconnects session id 15 or logoff session quser from the it-cor20 server.
