Permission denied when trying to run systrace

Question

I'm trying to run the new systrace tool provided by the Android SDK. As demoed during Google I/O 2012 (Demo starts at 31:04 in the video) (Terminal commands demoed at 32:04). .

However, when I try to run the command (in Terminal on a Mac) I get the following:

-bash: ./systrace.py: Permission denied

What am I doing wrong?

Thanks

I figured this out by learning more about UNIX permissions. The systrace.py file had its permissions set to: -rw-r--r-- so I wasn't allowed to execute it. I used chmod to change the permissions to allow me to execute it and now I can run it.

Also: in case it helps someone... trace.html does not open in Firefox, try using Chrome.
