configget

configget is a command-line utility designed to retrieve specific configuration values from various sources. It aims to simplify the process of accessing configuration settings that might be stored in files, environment variables, or other system-level configurations. The tool typically works by specifying a key or path to the desired configuration value, and configget then searches predefined locations or user-specified paths to find and return the corresponding value.

The primary advantage of using a tool like configget is its ability to abstract away the complexities of different configuration formats and locations. Instead of manually parsing configuration files or checking multiple environment variables, users can employ a single command to fetch the required information. This can be particularly useful in scripting and automation, where consistent and reliable access to configuration data is essential for program execution.

configget often supports multiple configuration backends, such as INI files, JSON files, YAML files, and environment variables. The order in which these backends are searched can usually be configured, allowing users to define precedence for different configuration sources. For example, a setting defined in an environment variable might override the same setting found in a configuration file. The output of configget is typically the raw value of the requested configuration item, making it easy to pipe into other commands or use within scripts. Some versions may offer options to specify output formats or to handle missing values gracefully.
