The command substuition captures the output of the perl-script at the shell-side.

So if you only have to pass one value you simply print it to standard output in Perl.

#in perl-script "script.pl"
print $variable;

#in the shell-script:
variable=$(perl script.pl)
echo $variable

If you must pass more than one variable you e.g. print them in a certain format "$var1=$var2=$var3" and parse that on the shell side.
