是否有(Unix)shell脚本将JSON格式化为可读格式?

基本上,我希望它转换以下内容:

{ "foo": "lorem", "bar": "ipsum" }

…变成这样:

{
    "foo": "lorem",
    "bar": "ipsum"
}

如果您想在控制台可视化json日志,可以使用munia漂亮的json

npm install -g munia-pretty-json

您的json数据(app-log.json)

{"time":"2021-06-09T02:50:22Z","level":"info","message":"Log for pretty JSON","module":"init","hostip":"192.168.0.138","pid":123}
{"time":"2021-06-09T03:27:43Z","level":"warn","message":"Here is warning message","module":"send-message","hostip":"192.168.0.138","pid":123}

运行命令:

munia-pretty-json app-log.json

下面是控制台上的可读输出:

您可以使用模板格式化输出。默认模板为“{time}{level-c}{{message}”

使用模板:

munia-pretty-json -t '{module -c} - {level} - {message}' app-log.json

输出:

或者,使用Ruby:

echo '{ "foo": "lorem", "bar": "ipsum" }' | ruby -r json -e 'jj JSON.parse gets'

使用Perl,如果您从CPAN安装JSON::PP,您将获得JSON_PP命令。从B Bycroft那里偷了一个例子,你会得到:

[pdurbin@beamish ~]$ echo '{"foo": "lorem", "bar": "ipsum"}' | json_pp
{
   "bar" : "ipsum",
   "foo" : "lorem"
}

值得一提的是,json_pap预装了Ubuntu 12.04(至少)和/usr/bin/json_pap中的Debian

PHP版本,如果您有PHP>=5.4。

alias prettify_json=php -E '$o = json_decode($argn); print json_encode($o, JSON_PRETTY_PRINT);'
echo '{"a":1,"b":2}' | prettify_json

JSONLint在GitHub上有一个开源实现,可以在命令行上使用,也可以包含在Node.js项目中。

npm install jsonlint -g

然后

jsonlint -p myfile.json

or

curl -s "http://api.twitter.com/1/users/show/user.json" | jsonlint | less
