Net::MAC doesn't reliably preserve case in a MAC address. 20 Just trying to figure out basic use of regexes with grep (or egrep) in mac terminal (BSD grep - 2.5.1-FreeBSD). Example: 7.122.32.41.5 (should be 0.7.122.32.41.5)Īrguably, that's their problem and not mine, but maybe someday I'll get around to supporting that case as well. Note that this works only if the host name can be resolved. Net::MAC can't handle MAC addresses where whole leading zero octets are omitted. Not sure how portable this is, but you can avoid the whole sed/grep/awk/perl etc with the hostname command and either -i or -I (I recommend hostname -I):-i, -ip-address Display the network address(es) of the host name.

In scalar context, it returns the number of times the expression was true. # Example: convert to a different MAC address format (dotted-decimal) The grep function evaluates a block or an expression for each element of a list and returns a list consisting of those elements for which the expression evaluated to true. my foo grep ( //, bar) weed out comments. By default grep doesn't support non-greedy modifiers, but you can use grep -P to use the Perl syntax. To get a non-greedy match in regular expressions you need to use the modifier after the quantifier. In scalar context, returns the number of times the expression was true. 7 Answers Sorted by: 373 You're looking for a non-greedy (or lazy) match. My $mac = Net::MAC->new('mac' => '08:20:00:AB:CD:EF') Evaluates the BLOCK or EXPR for each element of LIST (locally setting to each element) and returns the list value consisting of those elements for which the expression evaluated to true.
