Just to add another couple of options to anonymized user 468275's post. You can do this, if you don't care about the output from learn.sh:

    @args = ("learn.sh", "arg1", "arg2");
    system(@args) == 0
        or die "system @args failed: $?"

Whereas this does much the same as using backticks (``)

my $output = qx/learn.sh arg1 arg2/
