This tool provides a quick and easy way to check the value of environment variables on your system, making it especially useful for developers and system administrators who need to debug environment configurations.\n\n## Features\n\n- **Read Environment Variables**: Input the name of any environment variable, and the tool will display its value.\n- **User-Friendly Messages**: If the specified environment variable does not exist or is not set, the tool provides a clear and concise message indicating that the variable was not found.\n- **Cross-Platform Compatibility**: The tool works seamlessly on Windows, Linux, and macOS, making it a versatile utility for different environments.\n- **Simple and Lightweight**: Built with simplicity in mind, this tool has minimal dependencies and a small footprint.\n\n## Build and Installation\n\nTo build the `envar` tool, you need to have Rust installed on your system. You can install Rust using [rustup](https://rustup.rs/):\n\n```sh\ncurl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh\n```\n\nOnce Rust is installed, you can clone this repository and build the project:\n```sh\ngit clone https://github.com/dexcompiler/envar.git\ncd envar\ncargo build --release\n```\nThis will generate the executable in the target/release directory.\n\n## Usage\n### Basic Usage\nTo run the envar tool, simply execute the compiled binary and enter the name of the environment variable you wish to read:\n\n```shell\n./envar \u003cENV_VAR\u003e\n```\nFor example, the command:\n```shell\n./envar PATH\n```\nwill output the value of the \"PATH\" environment variable:\n```shell\nThe value of the environment variable 'PATH' is: /usr/local/bin:/usr/bin:/bin\n```\nIf an environment variable does not exist or is not set, the tool will display a message indicating that the variable was not found:\n```shell\nThe environment variable 'NON_EXISTENT_VAR' was not found.\n```\n\n### Help Option\nYou can also display usage instructions and examples by using the --help or -h option:\n```shell\n./envar --help\n```\nThis will display the following help message:\n```shell\nUsage: envar \u003cENV_VAR\u003e\nRetrieve the value of the specified environment variable.\n\nOptions:\n  -h, --help     Show this help message\n\nExamples:\n  envar PATH     Retrieve the value of the 'PATH' environment variable\n```\n\n## Contributing\nContributions are welcome! If you have suggestions for improving the tool or adding new features, feel free to open an issue or submit a pull request.\n\n## License\nThis project is licensed under the MIT License.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdexcompiler%2Fenvar","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdexcompiler%2Fenvar","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdexcompiler%2Fenvar/lists"}
