Hello,

I had this script but can't work

# read "input.txt"
open (FILE, 'org.log') or die "$!";
open (NEWFILE, '> joinline.txt') or die "$!";
$line = '';
while (<FILE>) {
chomp($_);
if ($_ ne '') {
$line = $line . "" . $_;
} else {
print "$line\n";
print NEWFILE "$line\n";
$line = '';
}
}
close (FILE);
close (NEWFILE);

gmstrftime - Format a GMT/UTC time/date according to locale settings

SYNOPSIS
string gmstrftime (string $format, [int $timestamp = time()]) DESCRIPTION
Behaves the same as strftime(3) except that the time returned is Greenwich Mean Time (GMT). For example, when run in Eastern Standard Time (GMT -0500), the first line below prints "Dec 31 1998 20:00:00", while the second prints "Jan 01 1999 01:00:00". PARAMETERS
o $format - See description in strftime(3). o $timestamp - The optional $timestamp parameter is an integer Unix timestamp that defaults to the current local time if a $timestamp is not given. In other words, it defaults to the value of time(3). RETURN VALUES
Returns a string formatted according to the given format string using the given $timestamp or the current local time if no timestamp is given. Month and weekday names and other language dependent strings respect the current locale set with setlocale(3). EXAMPLES
Example #1 gmstrftime(3) example <?php setlocale(LC_TIME, 'en_US'); echo strftime("%b %d %Y %H:%M:%S", mktime(20, 0, 0, 12, 31, 98)) . " "; echo gmstrftime("%b %d %Y %H:%M:%S", mktime(20, 0, 0, 12, 31, 98)) . " "; ?> SEE ALSO
strftime(3). PHP Documentation Group GMSTRFTIME(3)
All times are GMT -4. The time now is 06:41 PM.
