rg

"rg" stands for "ripgrep" and it is a command line tool used for fast and efficient searching in text files. It is designed to be faster than other similar tools like "grep" by utilizing parallel processing techniques. Rg supports various search patterns including regular expressions and it can search through multiple files and directories simultaneously. It is written in a system programming language called Rust, which emphasizes safety, concurrency, and performance. Rg provides many features such as line numbering, highlighting, including and excluding files or directories from search, and filtering by file types. It automatically ignores hidden files and directories by default, making search results cleaner. Rg's search results are colorized by default, making it easier to identify matching patterns. It supports smart case by default, which means if the search pattern contains uppercase letters, rg will perform a case-sensitive search; otherwise, it will perform case-insensitive search. Rg provides multiple command line options for customization and optimization, so users can fine-tune the search process according to their needs. It is widely used by software developers, system administrators, and power users to quickly search large codebases, logs, and other text files.
