The “uprecords” command is a Linux utility that displays a summary of historical uptime records. When you run the “uprecords” command in a terminal, it will show you a table that lists the top uptimes for your system, including the date and time of the last reboot.
The “uprecords” command retrieves the information from the “/var/log/wtmp” file, which contains a record of all system logins, logouts, and reboots. By default, the utility will display the top ten uptime records, but you can specify a different number of records to display using the “-n” option.
The table produced by the “uprecords” command lists the uptime records in descending order, with the longest uptime at the top. Each row of the table shows the number of days, hours, and minutes that the system has been up, as well as the date and time of the last reboot.
In addition to displaying the uptime records, the “uprecords” command can also generate a report that summarizes the average uptime, the total uptime, and the number of reboots for a specific time period. To generate this report, you can use the “-s” option followed by a start date and the “-e” option followed by an end date.
