That's not how the environment works. Changes are only visible to the current process and its children. You cannot change the "upwards" environment.

The traditional technique is to output a shell script that the "upper" process then evaluates:

# In the parent shell do:
$(perl -wle 'print "export pathy=kuku')
echo $pathy
