Beyond Bash Builtins: Crafting a Robust Bash Logging System

Many engineers have a love-hate relationship with Bash. This article details how the author built a robust Bash logging system to overcome Bash's limitations in error handling and data structures. By creating custom functions like `log::info` and `log::error`, and leveraging built-in variables such as `BASH_SOURCE`, `FUNCNAME`, and `BASH_LINENO`, the author achieved detailed logging and stack trace capabilities, significantly improving debugging efficiency for large Bash scripts. This system not only provides detailed error messages and locations but also avoids inconsistencies in Bash's built-in options, offering a new approach to building more robust Bash scripts.
