traveler has asked for the wisdom of the Perl Monks concerning the following question:

Hating to reinvent the wheel, I have searched SuperSearch and CPAN, but to no avail. I need to parse /proc/pci on a series of linux systems to try to discover their hardware configurations. Does anyone have a module to do this, or am I on my own?

    You should parse the output of the lspci program, instead. /proc/pci is in the process of being deprecated. lspci also offers a -m option, which is designed to make it simpler for scripts to parse.

      I should have noted that I am using mandrake 9.2: it does not have lspci.

        Hi!

        That's weird, you should have it in some package (maybe pciutils or a similar name).

    You're probably on your own. It's probably not too difficult - gratuitous globb'ing and regexen should get you where you need to go. If you get something working, feel free to post it to CPAN.

    The module that you want to take a look at is Proc::ProcessTable - I have posted a review of this module on this site previously here.

     

    perl -le "print+unpack'N',pack'B32','00000000000000000000001010001011'"

      I must be missing something. How do you use Proc::ProcessTable to retrieve the information contained in /proc/pci (or the detail contained in lspci)? I haven't checked the README, but the documentation at CPAN makes no mention of this.

      If things get any worse, I'll have to ask you to stop helping me.
