your regexp should looks like

(but most important) _Shortest_, script that cleans from a directory
files that are at least 3 days old.
Good luck all,
You're welcome to pick who you think is the winner.

S I guess I have to ask, what is this command? -newerct? I get the following
S when running this line:
S find: -newerct: unknown option
it depends of your find. this very far prom perl, but...
man find:
-newerXY file
True if the current file has a more recent last access time
(X=a), change time (X=c), or modification time (X=m) than the
last access time (Y=a), change time (Y=c), or modification time
(Y=m) of file. In addition, if Y=t, then file is instead inter-
preted as a direct date specification of the form understood by
cvs(1). Note that -newermm is equivalent to -newer.

LPD The solution i'm using now is this.
LPD is dirty and hogs much of the servers power when it
LPD runs but at the moment it's the only way for me
LPD to have access to this file.
LPD CODE
LPD open FICMSG, $logfile or print problem opening log file.;

1. you do not need $_ = $msg[$i]; string, becouse you do not use $_
variable.
2. you can shorten your code:
open FICMSG, $logfile or print problem opening log file.;
$i=0;
while($msg[$i] = FICMSG)
{
if ($i 40)
{
$i++;
}
else
{

3. please do not use that approach :)
LPD for($i = 0; $i = $#msg; $i++)
LPD {
LPD print bError $i:/bbr$msg[$i]\nbrbr;
LPD }
LPD /CODE
LPD My question is...can we read the file backwards.
LPD If I could set the reading pointer to the end
LPD of the file and then work my way back 40 entries.
LPD and print...now that would make my day.
LPD anyone know of a way?
yes. you can simply write
my @msg = `tail -40 $logfile`;
if you really want to read file from end to begin by yourself,
you should be familiar with system calls like seek (perldoc -f seek)
and tell (perldoc -f tell).
here is sample(taken from fido7.ru.perl, author Dmitriy Goldobin ):
sub PrintReverse
{
open FILE, shift; binmode FILE; seek FILE, 0, 2;
my $chunk = ;
for( my $pos = tell(FILE) ~2047; $pos = 0; $pos -= 2048 ) {
my $buf; seek FILE, $pos, 0; read FILE, $buf, 2048;
@_ = split /^/, $buf.$chunk;
$chunk = shift if $pos;
print pop while( @_ );

Re: Compare large files memory error
Hello Mbedish,

Mac Is there a better way to compare large files than this snippet,
Mac which runs out of memory if files 30mb.
Mac It is also slow, about the same speed as comparing in a text editor!
Mac Thank you.
Mac __SNIP__
Mac @file1 = (IN1);
Mac @file2 = (IN2);
first, it is a very bad practice to read entire file into memory. for
example, if file size is bigger than free memory, you'll have unpredictable
result.
second, the slowest operation in your example is file I/O. your files
may have differences in second string, so you do not need to read rest of
file.
Mac $are_equal = compare_arrays(\@file1, \@file2);
Mac if ($are_equal) {
Mac print Files are IDENTICAL \n;
Mac }
Mac else
Mac {
Mac print Files are DIFFERENT \n;
Mac }
Mac sub compare_arrays {
Macmy ($first, $second) = @_;
Mac#no warnings; # silence spurious -w undef complaints
third, you compare your arrays two times
first pass:
Macreturn 0 unless @$first == @$second;
second pass:
Macfor (my $i = 0; $i @$first; $i++) {
Macreturn 0 if $first-[$i] ne $second-[$i];
Mac}
Macreturn 1;
Mac}
Mac __SNIP__
so, i can recommend something like
$retval=1;
while( $a=IN1 )
{
$b=IN2;
if ($a ne $b)
{
$retval=0; last;
}
}
close IN1; close IN2;
return $retval;
at the beginning, you can compare files size (perldoc -f stat).

Can anybody tell me if - and how - it is possible to start my perl-scripts on computers without a perl interpreter, without an installed perl - on windows-computers of my coworkers? to Matthias: it depends... you need perl, that uses config files, not windows registry (activeperl can not help you there). then simply install perl on network drive, share them and add to path on coworkers computers ( drive letter should be the same ). take a look at http://www.cpan.org/ports/index.html, or you can take Perl-5.00502 at http://www.mysql.com/downloads/os-win32.html. he is very old, but still works. But, here you will have problems with new modules which you will install - you will need win32 C compiler. decision is yours.

NO.
