Hey everyone! I'm a C programmer and I occasionally dive into Bash scripting for automation tasks. Right now, I'm working on a somewhat complex script and using functions for the first time in a while. It's a bit confusing for me since in C, you use parentheses when defining and calling functions, but in Bash, you define a function with parentheses and call it just by its name. This makes it hard for me to remember that just writing 'get_path' is actually a function call. So, I'm wondering if there are any particular naming conventions for functions in Bash scripting? Would something like 'ft_get_path' be a good idea?

Bash functions mirror regular command usage, so they don’t use parentheses for calling. This adds to the power of Bash since it treats functions like any other command. If you've wrapped commands before, you already get that concept! Feel free to experiment with naming; just don't overlap with existing command names!
Interesting thing about Bash functions is they can technically be named anything you like. If you're looking for a convention, find something that works for you and just stick with it. I once made an alias called 'call' that was empty, so I could type 'call function.name' to help distinguish function calls. It's all about finding a method that feels right for you!
Function naming is really a matter of personal style! Just make sure you're consistent with whatever convention you choose, and definitely comment on your code when needed. It can help a lot in the long run.
In Bash, function naming is pretty flexible! It's not strict like some other languages. You can literally name your functions anything you want. However, it's good practice to stick to a convention that makes sense to you, like using prefixes or underscores to keep things organized. Consistency is key! Just keep things clear so you and others can read it easily.
I recently learned that you can use embedded colons in function names, like 'lib::parse'. It helps to create a namespace for clarity, which can keep your project organized. Just make sure your function names are distinct enough from existing commands to avoid confusion!
