To cap off a copper gas pipe, first turn off the gas supply. Clean the end of the pipe, apply flux to both the pipe and the cap. Slide the copper cap onto the pipe. Heat the joint with a propane torch until the flux bubbles, then apply solder until it flows into the joint. Finally, let it cool and check for leaks with a soapy water solution.
