in reply to grabbing dmidecode memory data - there's got to be a better way

I prefer NOT to call external utilities writing "human readable" data. The output formats often change without announcement, they are not properly defined, and some stupid tools insist on doing their own pager or wrap lines. So, my first approach is to search CPAN for DMI (after all, dmidecode just reads some file(s) in /sys or /proc):

The first one seems to read the DMI data directly (from /dev/mem, unfortunately, so it might need root privileges, whereas a tool reading from sysfs could live without root privileges), the other one attempts to parse dmidecode output.


Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)

    Well, in this particular environment I have root access, but can't install CPAN modules. They've got to be builtins, or none at all. I'm stuck scraping text for the time being, from a source format which WILL change without notice down the road, and already differs from one architecture to another.

    $ perl -MMIME::Base64 -e 'print decode_base64 "YWNlQHRvbW15YnV0bGVyLm1lCg=="'
