# When is this run ?

#
# uptime
#
# Start simple with a (nonroot) cron like this
#
#   6 * * * *  uptime >> ${HOME}/log/$(date +\%Y\%m\%d)_uptime.log
#
# then parse the output (should be 24 entries/day)
# For more fancy solutions, see http://stackoverflow.com/questions/79490/linux-uptime-history 

updateLogfile=/home/george/log/$(date +\%Y\%m\%d)_uptime.log
wc -l ${updateLogfile=} | sed 's/^/UptimeCount: /g'
