I am measuring the CPU usage of a running server process.

I use a shell to run perf stat -p <pid> & to attach to the process, run some commands, and kill -INT the perf to get the result.

The perf stat will output its result when being interrupted. But how do I capture the output from kill -INT into a bash variable?

Thank you!
