As a Linux system administrator, it is essential to know when your system was last rebooted. This information can be useful for troubleshooting and maintenance purposes.<\/p>\n

In this tutorial, we will go through the steps to check the Linux system reboot date and time using the “who -b”, “last reboot”, and “uptime” commands.<\/p>\n

Step 1: Check System Reboot Date and Time Using “who -b”<\/h2>\n

The “who -b” command displays the system’s last boot time. To use this command, open a terminal and type the following command:<\/p>\n

\r\nwho -b\r\n<\/pre>\n
The output will show the date and time when the system was last booted.<\/p>\n
\r\n[root@server ~]# who -b\r\n         system boot  2014-08-16 09:34\r\n<\/pre>\n
Step 2: Check System Reboot Date and Time Using “last reboot”<\/h2>\n
The “last reboot” command shows the history of system reboots. To use this command, open a terminal and type the following command:<\/p>\n
\r\nlast reboot\r\n<\/pre>\n
The output will display the reboot history, including the date and time of the last system reboot.<\/p>\n
\r\n[root@server ~]# last reboot\r\nreboot   system boot  2.6.32-431.el6.x Sat Aug 16 09:34 - 01:11  (15:36)\r\nreboot   system boot  2.6.32-431.el6.x Tue Aug 12 19:39 - 00:13  (04:33)\r\nreboot   system boot  2.6.32-431.el6.x Mon Aug 11 23:08 - 23:59  (00:50)\r\nreboot   system boot  2.6.32-431.el6.x Tue Aug  5 11:47 - 05:41 (5+17:54)\r\nreboot   system boot  2.6.32-431.el6.x Tue Aug  5 09:03 - 11:18  (02:15)\r\nreboot   system boot  2.6.32-431.el6.x Tue Aug  5 08:58 - 09:03  (00:04)\r\nreboot   system boot  2.6.32-431.el6.x Fri Jul 18 00:47 - 00:51  (00:04)\r\nreboot   system boot  2.6.32-431.el6.x Sun Dec  8 11:22 - 11:23  (00:01)\r\nreboot   system boot  2.6.32-431.el6.x Sun Dec  8 10:28 - 10:30  (00:01)\r\nreboot   system boot  2.6.32-431.el6.x Sat Dec  7 21:54 - 22:40  (00:46)\r\nreboot   system boot  2.6.32-431.el6.x Sat Dec  7 19:46 - 21:54  (02:08)\r\n\r\nwtmp begins Sat Dec  7 19:46:12 2013\r\n<\/pre>\n
Step 3: Check System Uptime<\/h2>\n
The “uptime” command shows how long the system has been running since the last reboot. To use this command, open a terminal and type the following command:<\/p>\n
\r\nuptime\r\n<\/pre>\n
The output will display the system’s uptime in days, hours, minutes, and seconds.<\/p>\n
\r\n[root@server ~]# uptime\r\n 01:13:34 up 15:38,  1 user,  load average: 0.04, 0.08, 0.04\r\n<\/pre>\n
