Hi All,
Can somebody please tell me what is the difference between "=" and ":=" sign in
case of perl??
I never saw ":=" in any perl code.
Also I checked perlop and didn't find that a symbol.

Passing arguments like this has no such problem.
But you'd better pass the hash as a reference to the subroutine.
exitint($hostname, \%login);
sub exiting {
my $hostname = shift;
my %
print "login: $login $hostname\n";
I don't see where you defined the variable of $login.
Have you 'use strict' and 'use warnings'?

And you may need to install the database driver, for example, you are
using Mysql, then should install DBD::mysql for DBI.
For other sources, try google "Ovid's CGI Course", I remember there is
such a free CGI course made by Ovid.

Hi,
If you're running a webprom under mod_perl, then Apache::DBI is maybe what you
wanted.

So write the code like:
unlink $file or die $!;
This will throw up an error message and die.

For SQLite, just perl -MCPAN -e 'install DBD::SQLite', then use the general DBI
to create and access SQLite database.
you even don't need to install SQLite binary program.

I think you should write with @files = to get the full path for
pdf files.
After that you pass the anex argument when calling the function:
my $status = Mail::SendEasy::send(
smtp => 'localhost' ,
...
anex => \...@files,
);

Hi,
seems you're in un*x shell, so ">" is a valid redirection for perl script's
output.
if you also want to redirect the stderr then do:
perl my.pl > out.txt 2>&1
redirect STDOUT in perl script itself:
open HD,">","out.txt" or die $!;
open STDOUT,">&HD" or die $!;
HTH.

system(...) or `...` will run another process but it's in the same terminal.
I'm not sure why you want to open another terminal for tasks. :)
