Run multiple instances of a Perl script

I have a Perl script which does some text processing. Now I want to run multiple instances of that script.

I tried to use the Parallel::ForkManager module to achieve this, but that module is not available on my server and I can't install it.

Is there any way to do this using Perl or shell script in the Unix environment.

Is using fork() possible? Then just do it the hard way and fork() in the program itself as you like. Or maybe write a wrapper in a pattern of fork();exec(); or system(); if you need any output.

In shell scripting you can do it so easily like below:-

your_perl_script.pl &
your_perl_script.pl &
your_perl_script.pl &
wait

Here total 3 instances of your Perl script will run parallel. If you want more just add more like above.
