well to be fair it was 7 years ago i answered this question. i' ve got no way to track down the examples now unfortunately
just run uprecords - - help for help. it is not always in / usr / local / bin
this however doesn' t take into account shutdowns. the pseudo user reboot only appears in last when the system reboot .
the pseudo user reboot logs in each time the system is rebooted. thus last reboot will show a log of all reboots since the log file was created .
this isn' t stored between boots, but the uptimes project is a third - party option to track it, with software for a range of platforms .
