Measure running time of a command PDF
Friday, 14 October 2011
If we want to know how much time runs an app from command line (for example compiling a kernel) we can use the following script:

time_measure
#!/bin/sh
t_start=$(/bin/date +%s)
$*
t_stop=$( /bin/date +%s )
time=$(/bin/expr ${t_stop} - ${t_start})
echo "Command completed in: ${time} seconds."

To measure time for the kernel to be compiled we will run:

  cd /usr/src
  time_measure make buildkernel kernconf=GENERIC


Don't forget to copy time_measure script in /usr/local/bin and to make it executable.
