Not to quarrel because your explanation of the regex problems is exemplary, but OP is clearly dealing with a multi-line logfile, in which some lines begin with ~|TOTAL. Hence, an array better matches the SOPW spec than the string is your "Test Case."

Aside to Bindo: Your spec comes up a little short of perfection because (very strictly speaking and very nitpicky) there's no requirement -- merely a single illustration -- that what's captured be numeric followed by a percent sign. What if the notation were hex, binary or some sort of non-Arabic numbers? In any case, I've treated you spec as "any line that begins with tilde, pipe, 'TOTAL' followed by anything" which is the only reason my regex differs from RMGir's:

#!/usr/bin/perl use 5.016; use warnings; #1061986 my @logfile = ("~|TOTAL 24.1% 0.4%", "~|not a total 11%", "~|TOTAL 21.0% 0.7%", "FOOBAR", "~|TOTAL 13.7% 10.2%", "~|TOTAL last5 6", ); my @FIGURE; for my $logentry(@logfile) { if ($logentry =~ /~\|(TOTAL.*)/ ) { push @FIGURE, $1; } else { say "\t \$logentry, $logentry, does not match pattern"; } } for (@FIGURE) { say $_; } =head execution: C:\> $logentry, ~|not a total 11%, does not match pattern $logentry, FOOBAR, does not match pattern TOTAL 24.1% 0.4% TOTAL 21.0% 0.7% TOTAL 13.7% 10.2% TOTAL last5 6 =cut

    [marto]: they still don't know there was a problem, nobody told them! :P
    [Corion]: marto: Ow! I would assume there is a cron job monitoring the free disk space and automatically opening a ticket at 90%, 95% and 100% usage...
    [Corion]: Even we had automatic emails back when we maintained the machine ourselves...
    [marto]: Corion you under estimate how lazy these admins are :P
    [Discipulus]: we too; using opsview alarms
    [marto]: the key word: outsourcing ;)
    [Corion]: marto: Yeah, feels like that ;) You could set up the cronjob that auto-creates tickets :-))
    [marto]: the ticketing system does not accept calls via email, nor has it a working API. It's tied into Active Directory for authentication and the Solaris boxes aren't on that domain
    [Corion]: The one thing I haven't figured out a solution to is how to get an edge-trigger instead of sending an email every 5 minutes if the usage is above 90%. I want one mail when it goes over 90% but no more emails as long as it stays between 90% and 95%.
    [Corion]: marto: Clever! ;)
