Perl Script to check file date and size

Hi guys, i am new to perl. I started reading the perl documents and try to come up with some logic.

I am trying to create a script that would go into a location, search for todays files, then searches for all .txt files from today.

If todays not found, its an error

If file size is less than 0kb, its an error

It should email me the results. Here is the code so far:

Code:
#!/usr/local/bin/perl
use strict;
use vars qw(%opt);
use vars qw(%logfiles);
use Data::Dumper;
use Carp;

my $foundmymessages;
my $errormymessages;

sub StartUp () {
   my $todaydate = `/location1/select.pl -0`; chomp $todaydate;
   my ($YYYY, $MM, $DD) = unpack("A4A2A2", $todaydate);
   my $yesterday = `/location1/seclect.pl -1`; chomp $yesterday;
   my ($YYYYY, $YMM, $YDD) = unpack("A4A2A2", $yesterday);
   $opt{TodayDate} = $todaydate;
   $opt{YYYY} = $YYYY;
   my ($foo,$YY) = unpack("A2A2", $YYYY);
   $opt{YY} = $YY;
   $opt{MM} = $MM;
   $opt{DD} = $DD;
   $opt{YYYYY} = $YYYYY;
   $opt{YMM} = $YMM;
   $opt{YDD} = $YDD;
   $opt{Error} = 0;
   $opt{EqualDelim}="========================================================================";
   $opt{DashDelim}="--------------------------------------------------------------------------";
} # end StartUp

sub Standby () {
   %logfiles = (
        'Location1' => "/loc/loc-01/logs/ser/Feed/TC`date '+%m%d%Y'`*.txt",
        'Location2' => "/loc/loc-02/logs/ser/Feed/TC`date '+%m%d%Y'`*.txt",
        'Location3' => "/loc/loc-03/logs/ser/Feed/TC`date '+%m%d%Y'`*.txt",
        'Location4' => "/loc/loc-04/logs/ser/Feed/TC`date '+%m%d%Y'`*.txt",        
    );

} # end Standby


sub scanLogs () {
   foreach my $logfileinstance (sort keys %logfiles) {
      my $lfile = "$logfiles{$logfileinstance}";
      

     

} # end scanLogs

So, is your script not working? Are you seeing any particular errors?

I am trying to build the logic to do the checks. I have not run the script yet as I know its not complete.

another approach - here is a bare bones perl example using stat, time functions and directory functions.

Unless you are doing this to learn perl, I would suggest a two line shell script using the unix find command, maybe like this:
Code:
#!/bin/ksh
# $1 == /path/to/files
 touch -t $(date +'%y%m%m0000') ./dummy
 find $1 -newer ./dummy -size +0 -name '*.txt'  > /dev/null
 exit $?

perl:
Code:
#!/usr/bin/perl -w 
sub checkfile{

      $today = time;
      $today -= $today % 86400;  # midnight in epoch seconds
      $return_value = 0;
                                    #  mtime in epoch seconds
      $mtime = (stat("$_[0]"))[9] || die "cannot stat file $!";  
      $size =  (stat("$_[0]"))[7];  # size in bytes
      $ok = "not ok";
      
      if( $size > 0 && $mtime >= $today )
      {
            $ok = "ok"; 
            $return_value = 1;           
      }
      print "$_[0] is $ok\n";
      return $return_value;
}

$found = 0;
opendir (DIRHNDL, "$ARGV[0]") ||  die "Cannot open directory $!";
@filelist = readdir (DIRHNDL);
closedir (DIRHNDL);

foreach $filename ( @filelist )
{
   if ($filename =~ /txt$/)
   {
     $found |= checkfile $filename;
   }
}
print "return status = $found\n";

exit 0;

Hi jim mcnamara, I have a simple and stupid question to ask you..

in your perl example.. where do the directory location go? is it like this:

Code:
opendir (DIRHNDL, '/location1/locat/*.txt' "$ARGV[0]") ||  die "Cannot open directory $!";

No. put the code in an executable file, call it myfile.pl
Code:
./myfile.pl /path/to/nowhere

where /path/to/nowhere is the full directory name.

Thanks jim mcnamara.

I am a bit confused. I was supposed to run this script on a unix host. Such as this way:

./(file name)

And inside the code, I am supposed to have path to directories where script is supposed to perform above checks..

Can you clarify what you meant?

Thanks
