Re: Re: Extracting System Info

The machine is a standard Intel Pentium PC. The section of /proc/pci I am interested in, looks like this:-

Bus 0, device 15, function 0
Unknown class: Unknown vendor Unknown device (rev 1).
Vendor id=135a. Device id=61.
Medium devsel. Fast back-to-back capable. IRQ 9
Non-prefetchable 32 bit memory at 0x412000000
I/O at 0x2080
I/O at 0x2400
I/O at 0x2410
Blah..
Blah..

I am interested in seeking out devices with this vendor and device id and then getting just the I/O entires (just 2nd and 3rd though, not interested in the first. I tried the posted example but got:

Name "main::DATA" used only once: possible type at line 6
readline() on closed filehandle main::DATA at line 6..

Ahhh...

The stuff that he put after the __END__ line gets read into the filehandle called DATA. So, what you want to do is open up /proc/pci yourself (since you won't have the data embedded in your script.)

Try putting this line before the while loop:
open(DATA, '/proc/pci') or die "Can't open /proc/pci: $!";
