【问题描述】：

我有 json 文件，我可以使用以下命令循环并获取所需的值。我试图在将这些值显示为表格格式时获得一些见解。我正在使用@tsv，但收到错误object ({"release":...) cannot be tsv-formatted, only array。如何获得以下输出显示？

我想要的输出如下所示：

Release         Installed    Latest    Old      Deprecated
-------         ---------    ------    ---      ----------
test-app        1.0.0        2.0.0     true     false

jq:

cat test.json | jq '.test[] | select((.outdated or .deprecated) and ((.release|startswith("update")) | not) and ((.release|startswith("upgrade")) | not))'

json:

{
    "test": [{
        "release": "myapp1",
        "Installed": {
            "version": "0.3.0",
            "appVersion": "v1.2.6"
        },
        "Latest": {
            "version": "",
            "appVersion": ""
        },
        "outdated": false,
        "deprecated": false
    }, {
        "release": "myapp2",
        "Installed": {
            "version": "6.5.13",
            "appVersion": "1.9.1"
        },
        "Latest": {
            "version": "",
            "appVersion": ""
        },
        "outdated": false,
        "deprecated": false
    }, {
        "release": "test-app",
        "Installed": {
            "version": "1.0.0",
            "appVersion": ""
        },
        "Latest": {
            "version": "2.0.0",
            "appVersion": ""
        },
        "outdated": true,
        "deprecated": false
    }, {
        "release": "update-app",
        "Installed": {
            "version": "1.0.0",
            "appVersion": ""
        },
        "Latest": {
            "version": "3.0.0",
            "appVersion": ""
        },
        "outdated": true,
        "deprecated": false
    }, {
        "release": "upgrade-app",
        "Installed": {
            "version": "2.0.0",
            "appVersion": ""
        },
        "Latest": {
            "version": "2.0.0",
            "appVersion": ""
        },
        "outdated": false,
        "deprecated": true
    }]
}

【解决方案1】：

@csv 和 @tsv 都需要一个数组作为输入，因此您只需将以下内容附加到您的 jq 过滤器：

| [.release, .Installed.version, .Latest.version, .outdated, .deprecated]
| @tsv

【讨论】：

不错！我做了cat test.json | jq '.test[] | select((.outdated or .deprecated) and ((.release|startswith("update")) | not) and ((.release|startswith("upgrade")) | not)) | [.release, .Installed.version, .Latest.version, .outdated, .deprecated] | @tsv' 并得到了这个结果test-app\t1.0.0\t2.0.0\ttrue\tfalse。添加标题的正确方法是什么？
