I need to log PC uptime. How I can do this?
uptime for this and I will when ubuntu is shutdown write this command output in a file.
If you are using Ubuntu
then add below lines in "/etc/rc0.d/S60umountroot" at the beginning.
or you can simply use
then it will gives details in
Note :- Please careful edit this file
If you are using CentOs, then do the same in "/etc/rc.d/rc0.d/S01halt", but note that it should be added in beginning of the file.
