How to get previous shutdown cause?
I try to get previous shutdown cause and when it happened but i don't know correct syntax.
syslog -k Sender kernel ???
I need to get date and time in start of the row and shutdown cause number in end of the row which can be negative number too.
Solution 1:
I usually just run
sudo grep "Previous shutdown cause" /var/log/system.log
or (if the above returns empty)
sudo zgrep "Previous shutdown cause" /var/log/system.log.*.gz
Solution 2:
In Sierra, use log:
log show --predicate 'eventMessage CONTAINS "shutdown cause"'
