dmidecode | perl -le '$o = qr/[^\n]+\n[^\n]+/; $a = join "", <STDIN>; +$a =~ s/(Socket Designation: RAM($o)Bank($o)Current($o)Type($o)Instal +led Size: \d[^\n]+\n)/print $1/smge'

There has GOT to be a better way to get the following block of text out of dmidecode...

        Socket Designation: RAM socket #0
        Bank Connections: 0
        Current Speed: Unknown
        Type: EDO DIMM
        Installed Size: 8192 MB (Single-bank Connection)

...while avoiding these "Not Installed" ones:

        Socket Designation: RAM socket #3
        Bank Connections: 3
        Current Speed: Unknown
        Type: DIMM
        Installed Size: Not Installed
        Enabled Size: Not Installed
        Error Status: OK

While I try to come up with a better regex that isn't so dang ugly, do you have any suggestions on improving it?


Somewhat less ugly:

dmidecode | perl -le '$o = qr/[^\n]+\n[^\n]+/; $a = join "", <STDIN>; +$a =~ s/(Socket Designation: RAM($o){4}Installed Size: \d[^\n]+\n)/pr +int $1/smge'

Update #2

OK, this seems to be working on both VMware and physical... for future reference. Thanks goes out to everyone who pitched in. This is a big step forward.

dmidecode | perl -e 'undef $/; for ( split /(?<=\n)\n+/, <> ) { print +if /RAM socket|Memory Device/ && !/(Not|No Module) Installed/ }'
$ perl -MMIME::Base64 -e 'print decode_base64 "YWNlQHRvbW15YnV0bGVyLm1lCg=="'

In reply to grabbing dmidecode memory data - there's got to be a better way by Tommy

      Should cpanminus be part of the standard Perl release?
