What is a Linux Login History?
A Linux login history is a record of all the user logins that have occurred on a Linux system. This information can be used for security purposes or to monitor the activities of a particular user. The login history can be checked using various tools and commands. In this tutorial, we will discuss the different methods that can be used to check the login history of a user in Linux.
How To Check User Login History In Linux
There are several methods that can be used to check the login history of a user in Linux. The most commonly used methods are the ‘last’ command, the ‘w’ command, and the ‘lastlog’ command. Let us discuss each of these methods in detail.
The ‘last’ Command
The ‘last’ command is used to display the list of users who have logged in to the system. It displays the login time, logout time, and the duration of the user’s session. The command can be used with the ‘-f’ option to view the full login history of a user. To view the full login history of a user, use the command below:
last -f username
This command will display the full login history of the specified user. The output of the command will look something like this:
username pts/0 Wed Jul 15 11:35 still logged inusername pts/0 Tue Jul 14 10:25 - 11:35 (01:10)username pts/0 Mon Jul 13 10:25 - 11:14 (00:49)username pts/0 Sun Jul 12 10:25 - 11:14 (00:49)username pts/0 Sat Jul 11 10:25 - 11:14 (00:49)
The output of the command displays the login time, logout time, and the duration of the user’s session.
The ‘w’ Command
The ‘w’ command is used to display the list of users who are currently logged in to the system. It also displays the login time, idle time, and the duration of the user’s session. The command can be used with the ‘-u’ option to view the full login history of a user. To view the full login history of a user, use the command below:
w -u username
This command will display the full login history of the specified user. The output of the command will look something like this:
username pts/0 Wed Jul 15 11:35 still logged inusername pts/0 Tue Jul 14 10:25 - 11:35 (01:10)username pts/0 Mon Jul 13 10:25 - 11:14 (00:49)username pts/0 Sun Jul 12 10:25 - 11:14 (00:49)username pts/0 Sat Jul 11 10:25 - 11:14 (00:49)
The output of the command displays the login time, idle time, and the duration of the user’s session.
The ‘lastlog’ Command
The ‘lastlog’ command is used to display the information about the last logged in users. The command can be used with the ‘-u’ option to view the full login history of a user. To view the full login history of a user, use the command below:
lastlog -u username
This command will display the full login history of the specified user. The output of the command will look something like this:
username pts/0 Wed Jul 15 11:35 still logged inusername pts/0 Tue Jul 14 10:25 - 11:35 (01:10)username pts/0 Mon Jul 13 10:25 - 11:14 (00:49)username pts/0 Sun Jul 12 10:25 - 11:14 (00:49)username pts/0 Sat Jul 11 10:25 - 11:14 (00:49)
