A regex you could use is: /hardware ethernet / && $MAC_ADR= $'; this checks to match the contents of the line to "hardware ethernet " and sets MAC_ADR to the remainder of the line after the match. This has an overhead since using $&,$` or $' in one regex means they're populated on ALL subsequent regexes, also true of $1..$9 an alternative is to use negative lookbehinds or even just plain old: $line =~s/hardware ethernet //;$MAC_ADR=$line; -- Frank Booth - Consultant Parasol Solutions Limited.
