How to pass an argument to a perl script

Question

 my @return = `at now +3 days -f test2.pl myargument 2>&1`;

How do I pass that myargument to my script test2.pl? In that code it returns an error.

This does not seem to be a problem with Perl, but with your usage of the `at` command. To make debugging easier, it may be better to rephrase this question without any references to Perl. e.g. try executing `echo hello world` in two minutes directly from the command line. — amon, Oct 03 '17 at 17:12

According to the documentation for at on my system, it reads bourne shell commands to be executed from from the file specified with -f or STDIN.

As such, the following should do the trick:

`printf %s 'test2.pl myargument' | at now +3 days 2>&1`;

In my script i need to send an email which needs to be sent in a later time handled by the at command. In your solution which works, it sends the email first then create the job. Please help – Cadz Oct 04 '17 at 09:49
I bet you actually used `\`test2.pl myargument | at now +3 days 2>&1\`` – ikegami Oct 04 '17 at 15:14
