Hi, this is a very interesting tool. But when i tried it as following steps:
1 perf record -g -p $pid sleep 30 ; perf script > out1.stack
2 ./stackcollapse-perf.pl ../out/out11.stack > out.folder1
there is no output at all at the command 2. Could sb. can tell me why and how to fix it?

stackcollapse takes the data from STDIN, not as an argument.

./stackcollapse-perf.pl < ../out/out11.stack > out1.folder1 should work.
