Code export please

AI ghive me a code block; a script or a command and I copy and paste it in to the host somewhere, usually SSH, and copy and paste back the output. Give me an export button for the code block and allow me to set in settings or anywhere, where that export goes. Then I can have a script chmod -x it and execute it with out put to a file I can sling straight back in to the chat (how exactly not got that far)
