So, the design goes like this, the script should process the last but one file which is not a tmp file ( that one that ends with tmp )

so once that is being processed, another tmp file would be created and the script should poll for it and once done it should start processing that

Please correct me if am wrong !

something like might help but it is made such a way to run ever

Code:

open(OUTPUT, ">>", "output.txt");

while (1) {

#Make it as ever running process

$file = `ls -lrt | awk '/SMSCDR/ { before = curr; curr = $9 }END{ print before }'`; 

#select the file which is last but one

next if ( $file =~ /tmp/ );

#if its the 'tmp' file dumper process is still active so don't process it else continue processing

open (FILE, "<", $file) or die  "Unable to open file $file <$!> \n";

#open the file and start processing

while(<FILE>) {
chomp;
my @arr = split(/></);
foreach (@arr) {
if( /xml version/ ) {
$c++;
print OUTPUT "\n";
}
if( />/ && /</ ) {
if( $c == 1 ) {
s/(.*)>(.*)<.*$/1|2/;
my($tmp1, $tmp2) = split(/|/);
$data .= (" " . $tmp2);
printf OUTPUT "%s ", $tmp1;
}
else {
s/(.*)>(.*)<.*$/2/;
printf OUTPUT "%s ", $_;
}
}
}
print OUTPUT "\n";
print OUTPUT "$data\n" if( /xml version/i );
}

close (FILE);

#continue with while loop, by this time dumper process might have completed and next file ready for processing
}

close(OUTPUT);

exit 0;

SPEEDY_BACKEND(1p)														SPEEDY_BACKEND(1p)

NAME

       speedy_backend - the backend process for a persistent Perl interpreter

SYNOPSIS

       none ; this program is not meant to be called directly.

DESCRIPTION

       speedy, short for SpeedyCGI, is a way to run perl scripts persistently, which can make them run much more quickly.

       After the script is initially run, instead of exiting, the perl interpreter is kept running inside a backend process, speedy_backend.  Dur-
       ing subsequent runs, this interpreter is used to handle new executions instead of starting a new perl interpreter each time.  A	very  fast
       frontend  program, speedy, written in C, is executed for each request.  This fast frontend then contacts the persistent Perl process, which
       is usually already running, to do the work and return the results.

       Each perl script runs in its own Unix process, so one perl script can't interfere with another.	Command line options can also be  used	to
       deal with programs that have memory leaks or other problems that might keep them from otherwise running persistently.

       The speedy front end connects to the back end process, speedy_backend, via a Unix socket in /tmp.  A queue is kept in a shared file in /tmp
       that holds an entry for each process.  In that queue are the pids of the perl processes waiting for  connections.   The	frontend  pulls  a
       process	out  of this queue, connects to its socket, sends over the environment and argv, and then uses this socket for stdin/stdout to the
       perl process.

FILES

       /tmp/speedy* A unix socket used to connect to the frontend process.
