I wanted to trace the system calls made by the find command to debug some performance issues however I could not figure out how to do this on Mac OS X Yosemite. How can I trace system calls for an arbitrary program similarly to what strace does on FreeBSD? I am especially interested in tracing file-system related calls.
You can use dtruss like in
sudo dtruss find ~/repo -depth 2 -type d -name '.git'
The manual page of that utility will help you to tailor the use of the tool to your needs.
