前文我们详细阐述了 find 命令的基本操作 帮你精通Linux：Find命令的八大属性 以及 find 命令的的高阶操作 帮你精通Linux：Find命令高阶操作4项动作 。然而，我们日用的高频查询往往极其简单，调用 find 命令颇为繁琐，此时我们需要 riggrep 的帮助。

riggrep - recursively search current directory for lines matching a pattern

一、riggrep操作概览

基本的操作命令为：

rg -options pattern path

其中遍历搜索“二进制文件”：

rg -uuu 与 grep -r 等效

二、查看帮助

首先，通过 tldr 快速查看帮助：

ripgrep
A recursive line-oriented CLI search tool.Aims to be a faster alternative to grep.More information: https://github.com/BurntSushi/ripgrep.

 - Recursively search the current directory for a regex pattern:
   rg {{pattern}}

 - Search for pattern including all .gitignored and hidden files:
   rg -uu {{pattern}}

 - Search for a pattern only in a certain filetype (e.g., html, css, etc.):
   rg -t {{filetype}} {{pattern}}

 - Search for a pattern only in a subset of directories:
   rg {{pattern}} {{set_of_subdirs}}

 - Search for a pattern in files matching a glob (e.g., README.*):
   rg {{pattern}} -g {{glob}}

 - Only list matched files (useful when piping to other commands):
   rg --files-with-matches {{pattern}}

 - Show lines that do not match the given pattern:
   rg --invert-match {{pattern}}

 - Search a literal string pattern:
   rg -F {{string}}

其次，通过起内建的 help :

➜  Public rg --help | tail
            file; otherwise, the file name will be shown as a prefix for each matched line.

            This flag overrides --no-filename.

    -w, --word-regexp
            Only show matches surrounded by word boundaries. This is roughly equivalent to
            putting b before and after all of the search patterns.

            This overrides the --line-regexp flag.

最后通过 manual 查阅：

三、常用操作

列出含有关键词的所有文件：

➜  Public rg -il javascript | head
Centuar-Emacs/README.md
JS-for-Data/04.objects-and-classes.org
Definitive-JavaScript/01.Types.Values.Variables.org
Definitive-JavaScript/02.Expressions.org
Definitive-JavaScript/03.Statements.org
Definitive-JavaScript/04.Objects.org
Definitive-JavaScript/05.Array.org
Definitive-JavaScript/09.classes.org
Definitive-JavaScript/08.function.org
Definitive-JavaScript/10.modules.org

其中短写的 -l 为 “-l, --files-with-matches”

以及反向搜索:

rg --invert-match {{pattern}}

最后是只搜索指定的文件类型：

   rg -t {{filetype}} {{pattern}}
