Real-time file usage info in OS X
Jonathan Rentzsch describes the details on how to use the command
line tool fs_usage to discover what files a program is opening, reading,
writing, saving, and so on. This could be is quite useful for figuring out
where a program is storing information or what might be going wrong with
a mis-behaving app.
Update:
For example, the following shows filesystem activity for Safari (-w forces a wide
detailed output and -f filesys shows only file system related output instead of
including network related output too).
sudo fs_usage -w -f filesys Safari
