I don't follow what you are trying to do. perf-script can pretty print
each sample -- time, cpu, task, pid/tid, etc (that option of perf-script
is really a misnomer and this should be a perf-dump command).
From there you want to process the samples?
If you know perl or python take a look at the scripts in
tools/perf/scripts/python. I have not written external scripts, so can't
offer any suggestions for you.
