+jq 备忘清单
+===
+
+这个快速参考备忘单提供了使用 [jq](https://stedolan.github.io/jq/) 命令的各种方法。
+
+入门
+----
+
+### 介绍
+
+jq 就像用于 JSON 数据的 [sed](./sed.md) - 您可以使用它来切片、过滤、映射和转换结构化数据
+
+- [jq 官网](https://stedolan.github.io/jq/) _(stedolan.github.io)_
+- [jq 命令使用](https://jaywcjlove.github.io/linux-command/c/jq.html) _(jaywcjlove.github.io)_
+
+安装
+
+```bash
+$ sudo apt-get install jq # Debian& Ubuntu
+$ sudo dnf install jq     # Fedora 
+$ sudo zypper install jq  # openSUSE
+$ sudo pacman -S jq    # Arch
+$ brew install jq      # macOS & Homebrew
+$ port install jq      # macOS & MacPorts
+```
+
+语法
+
+```bash
+$ jq [options] <jq filter> [file...]
+$ jq [options] --args <jq filter> [strings...]
+$ jq [options] --jsonargs <jq filter> [JSON_TEXTS...]
+```
+<!--rehype:className=wrap-text -->
+
+### 选项
+<!--rehype:wrap-class=col-span-2-->
+
+:- | -
+:- | -
+`-c`               | 紧凑而不是漂亮的输出
+`-n`               | 使用`null`作为单个输入值
+`-e`               | 根据输出设置退出状态代码
+`-s`               | 将所有输入读取（吸取）到数组中；应用过滤器
+`-r`               | 输出原始字符串，而不是JSON文本
+`-R`               | 读取原始字符串，而不是JSON文本
+`-C`               | 为 JSON 着色
+`-M`               | 单色（不要为JSON着色）
+`-S`               | 在输出上排序对象的键
+`--tab`            | 使用制表符进行缩进
+`--arg a v`        | 将变量 `$a` 设置为 value `<v>`
+`--argjson a v`    | 将变量 `$a` 设置为 JSON value `<v>`
+`--slurpfile a f`  | 将变量 `$a` 设置为从`<f>`读取的JSON文本数组
+`--rawfile a f`    | 将变量 `$a` 设置为包含`<f>`内容的字符串
+`--args`           | 其余参数是字符串参数，而不是文件
+`--jsonargs`       | 其余的参数是JSON参数，而不是文件
+`--`               | 终止参数处理
+
+学习示例

+
+### 获取一个键的值
+
+```bash
+$ echo '{"foo": 42, "bar": "less interesting data"}' | jq '.foo'
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash
+42
+```
+
+### 数组运算
+
+```bash
+$ echo '[{"name":"JSON", "good":true}, {"name":"XML", "good":false}]' | jq '.[1]'
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash
+{
+  "name": "XML",
+  "good": false
+}
+```
+
+### 构造一个数组/对象
+
+```bash
+$ echo '{"user":"stedolan","titles":["JQ Primer", "More JQ"]}' | jq '{user, title: .titles[]}'
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash
+{
+  "user": "stedolan",
+  "title": "JQ Primer"
+}
+{
+  "user": "stedolan",
+  "title": "More JQ"
+}
+```
+
+### 计算一个值的长度
+
+```bash
+$ echo '[[1,2], "string", {"a":2}, null]' | jq '.[] | length'              
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash                    
+2
+6
+1
+0
+```
+
+### 取出数组中的键
+
+```bash
+$ echo '{"abc": 1, "abcd": 2, "Foo": 3}' | jq 'keys'              
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash                          
+[
+  "Foo",
+  "abc",
+  "abcd"
+]
+```
+
+### 使用多个过滤器
+
+```bash
+$ echo '{ "foo": 42, "bar": "something else", "baz": true}' | jq '.foo, .bar' 
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash
+42
+"something else"
+```
+
+### 管道传递给下一个过滤器
+
+```bash
+$ echo '[{"name":"JSON", "good":true}, {"name":"XML", "good":false}]' | jq '.[] | .name'     
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash                                            
+"JSON"
+"XML"
+```
+
+### 条件语句判断
+
+```bash
+$ echo '[1,5,3,0,7]' | jq 'map(select(. >= 2))'        
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash                                            
+[
+  5,
+  3,
+  7
+]
+```
+
+### 每个输入调用过滤器
+
+```bash
+$ echo '[1,2,3]' | jq 'map(.+1)'
+```
+
+输出结果
+
+```bash
+[
+  2,
+  3,
+  4
+]
+```
+
+### 条件判断
+
+```bash
+$ echo '2' | jq 'if . == 0 then "zero" elif . == 1 then "one" else "many" end'
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash
+"many"
+```
+
+### 字符串插入值并进行运算
+
+```bash
+$ echo '42' | jq '"The input was \(.), which is one less than \(.+1)"'
+```
+<!--rehype:className=wrap-text -->
+
+输出结果
+
+```bash
+"The input was 42, which is one less than 43"
+```
