I'm working on a script that will run as a nightly cron job. My perl skills are not as strong as I would like and I'm hoping someone out there can help. The first task is to check if the previous script finished and if not, sleep 'till it does. (This works) The next task (my problem) is that the script should exit if a file does not exist. The script doesn't exit until it hits the copy command. I have also tried using "die" but the result was the same.

Thanks

do{
&proc_run;
} while $result ne"";
my $inow_fas  = "/inow/index-data/sfs-fas/fas.txt";
exit unless (-e $inow_fas);

my $dstamp = `date "+%m-%d-%Y"`;
chomp $inow_fas;
my $renamed_file = $inow_fas.$dstamp;
chomp $renamed_file;
`cp $inow_fas $renamed_file`;

--- snip (do other stuff) ---

sub proc_run{
        $result =`ps -aef|grep writekeyscmdline|grep -v grep`;
          sleep 60 if $result =~ m/writekeyscmdline/;
}

In the crontab I output all errors to a file in the /tmp directory. test -s is then used to see if the file is greater than 0, and if so the output is mailed to me. I would like to have the script exit with a descriptive error message.
