Additional information in the default script template header#592

### Discussed in https://github.com/DannyBen/bashly/discussions/591 <div type='discussions-op-text'> ^{Originally posted by **meleu** December 27, 2024} ## request I suggest to put in [the default script template header](https://github.com/DannyBen/bashly/blob/master/lib/bashly/views/command/default_script.gtx) an information saying that the code in that file is going to be put **inside a function**. Something like the second line below: ```bash echo "# this file is located in 'src/upload_command.sh'" echo "# the code here will be placed **inside a function**" ``` I'm not really suggesting this exact text, but the message I'd like to be conveyed. ## reasoning I'm used to put all bash code inside functions. Even for simple scripts, I create a `main` function and then call it with `main "$@"`. The very first time I was trying bashly, I've coded my `src/root_command.sh` as I would do with my usual way of coding, and it generated this: ```bash cli_upload_command() { # src/upload_command.sh hello() { echo "hello world" } hello } ``` That is actually valid and really works, but the "function inside a function" situation wasn't what I was expecting.</div>
