Hello,
Easy: awk and perl were created for this kind of stuff.
awk '$3 > tmax { tmax = $3; } END { printf "Maximum temperature was: %.1f °C\n", tmax; }' cputemp.log
More elaborate with the following input:
==== 20080419 02:32 63.3 C 20080419 02:34 64.1 C 20080419 02:36 63.9 C 20080419 02:39 65.3 C 20080419 02:42 64.2 C 20080419 02:49 65.32 C 20080419 02:53 65.3 C 20080419 03:02 64.2 C ====
$ awk ' $3 > tmax { tmax = $3; tdate = $1; ttime = $2; } END { printf "Maximum temperature was: %.1f °C on %s %s\n", tmax, tdate, ttime; }' cputemp.log Maximum temperature was: 65.3 °C on 20080419 02:49
