rg 命令

常用示例

说明

rg (ripgrep) is a fast, recursive grep alternative that respects gitignore rules by default. It searches directories for regex patterns, automatically skipping hidden files, binary files, and ignored paths. Ripgrep uses Rust's regex engine for speed and supports most Perl-compatible regex syntax. It's designed for searching codebases, automatically detecting and skipping binary files and respecting .gitignore patterns. Multiple patterns can be specified with -e. File type filtering uses built-in definitions (use rg --type-list to see available types). Custom globs with -g provide flexible include/exclude patterns. Output is colorized by default when writing to a terminal. Use --color=never for scripts or --color=always for piping to pagers.
