Record File Handle Usage in OSX
lsof is a helpful tool for looking at what files a process currently has open, however sometimes a process may only access a file for a second and
lsof may miss the moment.
For OSX we also have Instruments. This is included with XCode and is pretty straight forward to use:
- Open Instruments
- Select File Activity
- Select the process
- Hit Record
- Perform your action
- Stop Recording
You can also save the log for later analysis.
