How about this?
# untested
my @mac = map {/((?:[a-fA-F0-9]{4}\.){2}[a-fA-F0-9]{4})/ and $1} ( @offline
);

thanks
is there any other ways to do this. What I would like to do is something
like the following. I would like to grep out the second column which is the
mac id and store it into a variable called @mac. Any help would be great. I
am have brain drain.

Here is one solution...
For each item in @offline the MAC will be captured in the variable $1.
# untested...
for ( @offline ) {
if ( /((?:[a-fA-F0-9]{4}\.){2}[a-fA-F0-9]{4})/ ) {
print "MAC: $1\n";
}
else {
print "No MAC here\n";
}
}

I have a global variable name @offline. It has the following information
stored in the variable. What I need to do is parse or split the variable and
store the mac id in a variable . What is the proper way to do this?
