Thanks John, and Rob.
This reply is quite close to what I am going to do,
but some critical point is wanted here I'll try to explain
my question further
That's about the whole story, but I'll make it short.
For example, I have a list like this :
123ABCDEF456
123456
Hi all,
That's about the whole story, but I'll make it short.
For example, I have a list like this :
123ABCDEF456
123456
654WXYZ321
987654321
ABCDEF123456
WXYZ321
By user's INTEGER input , I will have to find how many similar
patterns are matched within the list according to certain chars
open my $fh, , items/list.db;
print while ($fh);
close $fh;
This is suppose to printout the content in items/list.db ,
but why I get somthing like GLOB(0x162aca7) ??
Thanks in advise.
my $fh;
open $fh, '', 'items/list.db' or die File error: $!;
It just the same as open my $fh =)
print while $fh;
Hmm. I guess this is not a 'read' argument
Thanks in advise anyway =)

You method does work !
However, you can write as :
$line[1] /= 1000;
# which is the same as $line[1] = $line[1] / 1000;

First, your Perl is not a complete version of Perl. You just have the
compiler of Perl.
You almostly missed some very important modules such as strict, warnings,
CGI..etc.
And second, your Perl is out of dated. for Win32 OS, Perl is up to 5.8.0

How can I do this ? Or could it be done ?
Open some files ( unknown number of files ), depends on users demand.
Then start looking for some desired line ( use regex ).
I have an array to carry the info of matched data ( from which file, which line ).
while the $#array is 99 and all files would
I hope to design an interface of a function like this (not in OO way) :
sub tell_error
{ print Error for @_ }
sub Check_err
{ my %argv = @_;
}
Check_err ( TYPE = [1, 1, \tell_error('Type')], DATA = [ 1, 2, \tell_error
('Data')] );
In Check_err, I want tell_error ('Type')
I have a number $page = 500;
now i want to check that if $page matches a word character then make $page
=1;
$page = 1 unless ( $page =~ /\d/ );
or
$page = 1 if ($page =~ /\D/ );
so originally i did this
my $page =500;
if(($page =~ /\w/) || ($page = 0)){
$page=1;
}
print$page;
\w
if ( -d $path ) { print Directory }
elsif ( -f $path ) { print File }
else { print Not exist }

Yep ! =)
Even though I can't imagine what a path is not file or directory would imply
more then not exist. But I agree to check the existence for a path by -e

You want seek(), and possibly tell().
perldoc -f seek
Thanks for reply, but seems I have to clarify my question.
'seek' and 'tell' only helping me to target my position within
a file handle.
Say, if I have a 1MB file, and I just want to over write
bytes from 0 to 1000 byte then my job
You will probably want to open the file with a mode of +.
