Two ways:

Easy but not so efficient:

Code:
for MYmac in 0012CFCDA11A 0012CFCDA123 0012CFCD7123
do
    zcat /var/log/messages.2.gz | awk -v MAC=$MYmac -v C=0 '{ if ($0 ~ "DHCPDIS.*94.18.*"MAC ) C++ } END { print C, MAC }'
done

Efficient but more complex, is to put your Mac-list into the file "macs" and process file and stdin with awk:

Code:
zcat messages.gz | awk '{ F+=(FNR==1);
       if (F==1) cnt[$1]=0;
       if (F==2 && $0 ~ "DHCPDIS.*94.18") {
            MAC=gensub(/^.*ZEMdhcp: ([^:]*):.*/, "\\1", "");
            if (MAC in cnt) cnt[MAC]++;
       } } END { for(i in cnt) print cnt[i], i } ' macs -

MACLABEL(7)					       BSD Miscellaneous Information Manual					       MACLABEL(7)

NAME
maclabel -- Mandatory Access Control label format DESCRIPTION
If Mandatory Access Control, or MAC, is enabled in the kernel, then in addition to the traditional credentials, each subject (typically a user or a socket) and object (file system object, socket, etc.) is given a MAC label. The MAC label specifies the necessary subject-specific or object-specific information necessary for a MAC security policy to enforce access control on the subject/object. The format for a MAC label is defined as follows: policy1/qualifier1,policy2/qualifier2,... A MAC label consists of a policy name, followed by a forward slash, followed by the subject or object's qualifier, optionally followed by a comma and one or more additional policy labels. For example: biba/low(low-low) biba/high(low-high),mls/equal(equal-equal),partition/0 SEE ALSO
