Check Last Logon User’s Time Windows Linux Command Line

Many times we have to check the server logs for the security reason who is trying to access the server or when something went wrong. Admin have to check the logs using “eventvwr” to identify that who changed or from where the server last accessed. to check last user’s login time we can perform the following commands:

For windows Users: Open Command Promt and type “last” command without quote.

last # Last command will display current user logged in time detail.

Output:

Administ tty0 client01 Tue May 24 18:15 still logged in
Administ tty0 client01 Tue May 24 18:11 – 18:15 (00:03)
Administ tty0 client01 Tue May 24 18:11 – 18:11 (00:00)
Administ tty0 client01 Tue May 24 18:10 – 18:11 (00:00)

last username # It will display specified user log in time.

Output:

C:\Users\Administrator>last testuser

net user administrator | findstr /B /C:”Last logon”

Output:
