Some cmd line examples: $ buildstats.sh -s 'utime' Buildstats' data covers proc's stats in different areas, including CPU times, IO, program system resources and child program system resources. In order to print values on each of these sets from command line, one can use the following: $ buildstats.sh -H -s 'TIME' | less $ buildstats.sh -H -s 'IO' | less and 'RUSAGE' and 'CHILD_RUSAGE' for program and program's child system resources.
