I have a cron job set to run a script everyday. If I run the script out side of cron it runs correctly. If cron runs the script is produces a 0 byte file and it puts the output in the / directory. The script is set to put the output in a specific directory. Any help would be appreciated.

check your 'script' for any type of the environment variables and make sure those are accessible from within cron.

I thought I read that cron needs to be able to see the path to the script or parameteres within the script. Is this set in /etc/default/cron.

Below is a copy of the script, (message_log.pl).

# more message_log.pl
#!/usr/local/bin/perl
#! /usr/bin/ksh
#MagicStore message log utility
( $sec, $min, $hour, $mday, $mon, $year,, ) = localtime();
$today = sprintf( "%04d%02d%02d", ( $year + 1900 ), ( $mon + 1 ), $mday );
print "Parsing through message log...........\n";
sleep 2;
system("mkdir log") if (! -d "./log");
InstallScript();

system("./dl.csh > /images_1/messages/dl.out");
system("./dl.awk /images_1/messages/dl.out > /images_1/messages/dl1.out");
#---------------Set the line below to what type of message you want to trap-----
---------
system("grep PAT_INCONSISTENT /images_1/messages/dl1.out>$today.message.log");
system("rm -f /images_1/messages/dl.out");
system("rm -f /images_1/messages/dl1.out");
print "Your file named $today.message.log is ready for viewing\n";

sub InstallScript
{

unlink("/images_1/messages/dl.csh");
open(CSH,">/images_1/messages/dl.csh");
print CSH "#!/bin/csh\n";
print CSH "source ~work/.cshrc\n";
print CSH "source /home/sn_root/bin/apc/apc_env.csh\n";
print CSH "/home/sn_root/bin/apc/apc << EOF\n";
print CSH "4\n11\n5\n1\nEOF\n";
close(CSH);
system("chmod a+rwx /images_1/messages/dl.csh");

unlink("/images_1/messages/dl.awk");
open(AWK,">/images_1/messages/dl.awk");
print AWK "#!/usr/bin/nawk -f\n";
print AWK 'BEGIN { FS="\n";';
print AWK 'RS = "" }';
print AWK "\n";
print AWK "{\n";
print AWK 'if(sub(/^ date *:/,"",$1)) {';
print AWK "\n";
print AWK 'sub(/^ message *:/,"",$2)';
print AWK "\n";
print AWK 'print $1,$2';
print AWK "\n";
print AWK "\n}\n}";
close(AWK);
system("chmod a+rwx /images_1/messages/dl.awk");

}

your perl is making some assumptions that might not hold true under cron - in terms of file paths:

system("mkdir log") if (! -d "./log");
system("./dl.csh > /images_1/messages/dl.out");
system("./dl.awk /images_1/messages/dl.out > /images_1/messages/dl1.out");
print CSH "source ~work/.cshrc\n";

Where and how do i modify the paths in cron. Or do i need to modify the script?

I'd modify the script to make it aware of:

Once cron references the script shouldn't the script already know where to go? Below is a listing from cron and it is already in the correct directory?

30 07 * * * /images_1/messages/message_log.pl
