この配列内の各オブジェクトをループし、AssetId
およびconsole.log()
itという各キーの値を取り出したいと思います。コマンドラインにjqを使用してこれをどのように行うのですか?
コマンドラインツールjq
は、STDOUTおよび/またはSTDERRに書き込みます。 .AssetId情報をSTDOUTに書き込む場合、1つの可能性は次のとおりです。
jq -r ".[] | .AssetId" input.json
出力:
14462955
114385498
29715011
98253651
より堅牢な呪文は次のようになります。.[] | .AssetId?
ただし、「AssetId」という名前のキーがない場合は、選択内容によって異なります。
このコマンドを使用して実行することもできます。
jq ".[].AssetId" input.json
配列のような場合は私の場合です
{
"resultCode":0,
"resultMsg":"SUCCESS",
"uniqueRefNo":"111222333",
"list":[
{
"cardType":"CREDIT CARD",
"isBusinessCard":"N",
"memberName":"Bank A",
"memberNo":10,
"prefixNo":404591
},
{
"cardType":"DEBIT CARD",
"isBusinessCard":"N",
"memberName":"Bank A",
"memberNo":10,
"prefixNo":407814
},
{
"cardType":"CREDIT CARD",
"isBusinessCard":"N",
"memberName":"Bank A",
"memberNo":10,
"prefixNo":413226
}
]
}
以下のjqコマンドでprefixNoを取得できます。
jq ".list[].prefixNo" input.json
Jqでの配列反復のより具体的なケースについては、 this blogpost を確認できます。
ループ自体を実行するための選択肢がいくつかあります。ピークの素晴らしい答えを適用して、その周りにシェルループをラップできます。 echoを実行するスクリプトに置き換えます。
$ jq -r ".[] | .AssetId" input.json | xargs -n1 echo # this would print
14462955
114385498
29715011
98253651
$ for i in $(jq -r ".[] | .AssetId" input.json)
do
echo $i
done
14462955
114385498
29715011
98253651
