Thx Johngg

I stick to the non-die solutions. They are not real handy in 24/7 operational systems.... ;)

    Well, you don’t need to use die to get information from $!:

    #! perl use Modern::Perl; for my $file ('465_SoPW.pl', 'Non-Existent.txt') { if (my @stats = stat $file) { say "File '$file' last modified: ", $stats[9]; } else { say "stat failed for file '$file': $!"; } }

    Output (on my machine):

    0:17 >perl 466_SoPW.pl File '465_SoPW.pl' last modified: 1357188675 stat failed for file 'Non-Existent.txt': No such file or directory 0:17 >

    Hope that helps,

    The solution was $! and, as Athanasius points out, die had nothing to do with it other than to illustrate that the variable is available ;-)

    Cheers,
