Dear porters,
hopefully I am not doing some very stupid mistake at the end of a hard
working week, but the following script hangs (probably while trying to
flock) when I run it on the command line on my Debian Linux (unstable):
#!/usr/bin/perl -w
use strict;
use POSIX;
use Fcntl ':flock';
my $FILE = '/home/alex/data.txt';
my $url = $ENV{HTTP_REFERER} || '???';
my %hash;
open FILE, "+<$FILE" or die "Не могу открыть $FILE: $!\n";
flock FILE, LOCK_EX or die "Не могу поиметь $FILE: $!\n";
seek FILE, 0, SEEK_SET;
while (<FILE>)
{
$hash{$1} = $2 if /^(\S+) (\d+)$/;
}
seek FILE, 0, SEEK_SET;
$hash{$url}++;
for (keys %hash)
{
printf FILE "%s %i\n", $_, $hash{$_};
}
close FILE;
I am using the following Debian packages
ii perl-5.005 5.005.03-4 Larry Wall's Practical Extracting and Report
ii perl-5.005-base 5.005.03-4 The Pathologically Eclectic Rubbish Lister
And the perl -V gives:
