此外，请务必查看JSONFUI:一个支持折叠的命令行JSON查看器

TL；DR：对于性能，请使用jj-p<my.json。

基准

我在这里采取了一些解决方案，并用下一个虚拟脚本对它们进行了基准测试：

function bench {
    time (
      for i in {1..1000}; do
        echo '{ "foo" : { "bar": { "dolorem" : "ipsum", "quia" : { "dolor" : "sit"} } } }' \
        | $@ > /dev/null
      done
    )
}

这是我的mac（32 GB，苹果M1 Max，YMMV）上的结果：

bench python -m json.tool
# 8.39s user 12.31s system 42% cpu 48.536 total
bench jq
# 13.12s user 1.28s system 87% cpu 16.535 total
bench bat -p -l json # NOTE: only syntax colorisation.
# 1.87s user 1.47s system 66% cpu 5.024 total
bench jj -p
# 1.94s user 2.44s system 57% cpu 7.591 total
bench xidel -s - -e '$json' --printed-json-format=pretty                      
# 4.32s user 1.89s system 76% cpu 8.101 total

感谢@peak和您对jj发现的回答！

有TidyJSON。

它是C#，所以也许你可以让它用Mono编译，并使用*nix。但没有保证，抱歉。

JSON Ruby Gem与一个shell脚本捆绑在一起，以美化JSON：

sudo gem install json
echo '{ "foo": "bar" }' | prettify_json.rb

我正在使用httpie

$ pip install httpie

你可以这样使用
