I want to write the following bash script to perl

#write out current crontab
crontab -l > mycron
#echo new cron into cron file
echo "00 09 * * 1-5 echo hello" >> mycron
#install new cron file
crontab mycron
rm mycron

In perl, when I convert to

my $cronjobs = `crontab -l`;
my $raw = "00 09 * * 1-5 echo hello";
$cronjobs .= $raw;
say `crontab $cronjobs`;

but the above perl doesn't work. why ?

@simbabqueThe question is about perl script. not bash script. – Vishnu Nov 14 '16 at 16:21

Anything you can do from bash, you can do from Perl too. – Dave Cross Nov 14 '16 at 16:48

Why use Perl then? – reinierpost Nov 14 '16 at 23:27
The project is written in perl already. – Vishnu Nov 15 '16 at 01:07
