To counting how long process on a non-web based application will take time, perhaps you can try stopwatch application. For some OS, this kit is a build-in feature or at least it’s available on repositories. Below picture explain kind-of stopwatch application on Ubuntu 10.04 downloaded from default repository.
In a meantime you need to perform benchmark on an application but don’t have any internet connection to get those stopwatch (or you have forget to carry-up your watch or cell-phone), you can try to build your own stopwatch kit. The sample below, explain you how to make it from bash scripting shell & absolutely this is a universal kit for multi-platform on UNIX.
while true; do
DIFF=$(($NOW - $BEGIN))
MINS=$(($DIFF / 60))
SECS=$(($DIFF % 60))
printf "\rTotal Waktu: %d:%02d" $MINS $SECS
Save the script above on text editor and make it executable. Run it from console & do whatever you want to do after doing that.
Have a great day!
