downtimes
DOWNTIMES(1) General Commands Manual DOWNTIMES(1) NAME
downtimes - display system downtime records made by downtimed(8) SYNOPSIS
downtimes [-d downtimedbfile] [-n num] [-s sleep] downtimes -v downtime [-d downtimedbfile] [-n num] [-s sleep] downtime -v DESCRIPTION
The downtimes command displays the contents of the downtime database in human readable format. The downtime database is maintained by down- timed(8). The singular form downtime displays details only about the last time the system was down, whereas the plural form downtimes displays all records in the database. The -n option can be used to specify the number of downtime records to display. OPTIONS
-d downtimedbfile Use the specified downtime database file instead of the system default. -n num Define how many latest downtime records to output. Default is all. -s sleep Calculate the approximate crash time by specifying what was the sleep value of downtimed(8). -v Display the program version number, copyright message and the default settings. EXIT STATUS
The program exits 0 on success, and >0 if an error occurs. SEE ALSO
downtimed(8), uptime(1), http://dist.epipe.com/downtimed/ BUGS
The reporting accuracy in case of a system crash depends on how often the time stamp is updated. COPYRIGHT
