[Chicago-talk] logging in and out files

[tiger peng]

Hello all,

Does anyone have the experience on tracing input/output files used by Perl 
script?

I am think if there is anyway to over write the build-in open function, so the 
new open function can log the file name, IO type (R, W, or RW), as well as the 
open/close timestamp. Any suggestion is highly appreciated. 


Thanks,
Tiger
