Packet Squirrel payloads can be written in any standard text editor, such as notepad, vi or nano.
Payloads may be written in bash, Python or PHP and as such must be named payload.sh, payload.py or payload.php respectively. Additionally a payload.txt file will be processed according to its interpreter directive.
All payloads should begin with an interpreter directive. For example, bash payloads should begin with the typical shebang /bin/bash
Similarly, Python payloads should begin with shebang /usr/bin/python
