If you are doing some scripting and using ‘time’ command, then you know sometimes it becomes difficult to capture the output as the output would be something like this:
: amit ; time ls real 0m0.002s user 0m0.000s sys 0m0.001s
So, it is better to change that format. Here is simple example:
-
1
- TIMEFORMAT=’real %3R user %3U sys %3S pcpu %P’ time ls
- amit ; TIMEFORMAT=’real %3R user %3U sys %3S pcpu %P’ time ls
- 0.00user 0.00system 0:00.00elapsed 0%CPU (0text+0data 2432max)
- 0inputs+0outputs (0major+109minor)pagefaults 0swaps
- amit ; TIMEFORMAT=’real %3R user %3U sys %3S’
- amit ; time ls
real 0.001 user 0.001 sys 0.000 - amit ;
- amit ; TIMEFORMAT=’TIMEOUTPUT = real %3R user %3U sys %3S’
- amit ; time ls
TIMEOUTPUT = real 0.001 user 0.001 sys 0.000 - amit ;
