Re^7: Read UNIX environment variable

Well, it works from the prompt but not via cron.

use strict;
use warnings;
use MIME::Lite;

# from the link you gave
sub get_login_env {
  local %ENV;
  my $shell = shift || (getpwuid($<))[8];
  my $env = `echo env | perl -e 'exec {"$shell"} -sh'`;
  if (wantarray) {
    my @pieces = ( $env =~ m/^(.*?)=((?:[^\n\\]|\\.|\\\n)*)/gm );
    s/\\(.)/$1/g foreach @pieces;
    return @pieces;
  }
  else {
    return $env;
  }
}

%ENV = (%ENV, get_login_env());
my $mailvar = $ENV{'TESTMAILUSRS'}; 
my @mailUsers;
my $msg = new MIME::Lite();
$msg->build(
  From            =>    'us@here.com',
  Subject        =>    'Email from perl via cron',
  Type            =>    'text/html',
  Data            =>    'testing',
    Debug            => 1

);

for (split /[\s\n]/, $mailvar){
    if($_){
        $msg->add(To    =>    $_);
    }
}

eval { $msg->send };
die "MIME::Lite->send failed: $@\n" if $@;

How does it fail for you? Does `sh` pick up the correct environment? Maybe you set some environment variables in another rc file, or in `.profile` or `.kshrc`. Start some debugging.	[reply] [d/l] [select]

I don't get the email sent, I don't see an error message in the mailbox for the user cron is runing as. If I use the data dumper module and add `print Dumper(\%ENV);` to the code I can see the env vars when running it interactivly. Can you please let me know how I can debug this issue? Thanks	[reply] [d/l]

The cron daemon usually sends the output of a program via mail to the owner submitting the job. Find out how to configure your cron daemon to do that, and/or consult with your system administrator how to modify your system setup to do this. Alternatively, write debugging information from your program to a file so you can see how your program progresses and what values it finds, and where.	[reply]
