what files a program reads
 

Hi!
I'd like to know what files a program is using (reading) when is runnig.
Anyone knows a linux software for that task?
Thanks,

Regards

Hi,

Only way I know how to do that (the running program is a binary, right?):

Use strace / truss. You probably end up with more info than you need, but that you can filter.

See manpage for details on how to use.

Just popped into my mind: lsof must be able to do this too.

Hope this helps.

Ok, thanks!
Both lsof and strace look promising.
However what is this truss? I don't have it in none of my systems...

Hi,

truss is the unix version of strace (well, close enough).

Could even be that there is a linux version, I've never seen one, but I never actually looked for it. strace/lsof do what I want on a linux box.

Hope this clears things up a bit.

Definitely; thanks again.

Regards
