clang-format:tldr:f5461

This command is using the clang-format tool to generate a configuration file and then redirecting the output to a file. Let's break it down:

• clang-format: This is the name of the command-line tool that is used to format C, C++, Objective-C, and some other languages code. It is part of the LLVM project.
• --style=${select}: This option is used to specify the style for formatting the code. The ${select} is a placeholder that you need to replace with an actual style name. Clang-format provides a set of predefined styles such as LLVM, Google, Chromium, etc. You can choose one of these styles or create your own custom style.
• --dump-config: This option is used to generate a configuration file containing the current formatting style settings. It outputs the configuration in a specific format that can be later used by clang-format to format the code consistently.
• > ${-clang-format}: This part of the command is used for output redirection. It redirects (or pipes) the output of the previous command (--dump-config) to a file whose name is ${-clang-format}. The ${-clang-format} is another placeholder that needs to be replaced with an actual file name. This will create a new file with the content of the generated configuration file.

Overall, this command executes clang-format with the specified style, generates a configuration file with the current style settings, and saves it to a file.
