This complements --output file option, and is mutually exclusive with it. 3>results perf stat --log-fd 3 -- $cmd 3>>results perf stat --log-fd 3 --append -- $cmd The perl distro's make test.valgrind target uses valgrind's --log-fd option, I've adapted it to invoke perf also, and tested this patch there.
