examples: execute bash sessions in script environment Previously, the sessions contained only explicitly exported variables and functions. This was fragile and in part buggy due to lacking exports. Interactive features like user-defined aliases and functions are still working as before. 2020-05-17 15:25:40 +03:00			`# Start an interactive bash session in the current bash environment.`

examples: improve shell session usability - Add usage prompt when starting shell sessions - Give all examples an uniform interface ("c") for running commands or starting a shell on the node. 2020-05-18 00:46:44 +03:00			`USAGE_INFO='`
