One of the nicest features of OWASP ZSC shellcode is the ability to get Shellcode from Shell-storm database: http://shell-storm.org/shellcode/
For those unfamiliar with Shell-storm, this website contains a very reliable source of payloads and you can easily get them through the search function in OWASP ZSC
zsc --show-payloads --shell-storm
You can search for a specific shellcode/payload using the search command
shellcode, and then
search commands to search for a shellcode. After that shellcodes will be listed for you with title name , ID and etc. You can download them with following
shellcode and then
download command to download them with the ID which is shown to you.
For canceling each section, you can use
restart command to restart the software and start a new task.
