如何将 JQ 中数组中的各个元素传递给 xargs
我有一个这样的数组：
[
{
"customer": {
"id": "61ae22891dbcb5200f4af298",
"customerId": "C0001346",
"companyName": "Real Constructions",
"displayName": "Real Constructions",
"fullName": "NiyatiU",
"email": "[email protected]",
"phone": "(987) 654-3209"
},
"address": {
"streetName": "NY",
"state": "NY",
"city": "NY",
"zipcode": "39092"
}
},
{
"customer": {
"id": "61ae29f31dbcb5200f4af2b2",
"customerId": "C0001347",
"companyName": "UK Reality",
"displayName": "UK Reality",
"fullName": "VatsalShah",
"email": "[email protected]",
"phone": "(766) 688-1348"
},
"address": {
"streetName": "Queens",
"state": "NY",
"city": "Queens",
"zipcode": "11354"
}
}
]
我想将每个对象作为单独的参数传递给 xargs 和 curl。伪代码如下
jq '. | map(@json) | join("\\0")' http/customer/us/customers.json \
| xargs -0 -n 1 -I % curl -X POST http://localhost:3000/customers -d '%'
但我得到：
xargs: insufficient space for argument
因为我认为 json 元素太大了。我不想写一堆文件。
I have an array like such:
[
{
"customer": {
"id": "61ae22891dbcb5200f4af298",
"customerId": "C0001346",
"companyName": "Real Constructions",
"displayName": "Real Constructions",
"fullName": "NiyatiU",
"email": "[email protected]",
"phone": "(987) 654-3209"
},
"address": {
"streetName": "NY",
"state": "NY",
"city": "NY",
"zipcode": "39092"
}
},
{
"customer": {
"id": "61ae29f31dbcb5200f4af2b2",
"customerId": "C0001347",
"companyName": "UK Reality",
"displayName": "UK Reality",
"fullName": "VatsalShah",
"email": "[email protected]",
"phone": "(766) 688-1348"
},
"address": {
"streetName": "Queens",
"state": "NY",
"city": "Queens",
"zipcode": "11354"
}
}
]
and I would like to pass each object as a seperate param to xargs and curl. Psuedo code like
jq '. | map(@json) | join("\\0")' http/customer/us/customers.json \
| xargs -0 -n 1 -I % curl -X POST http://localhost:3000/customers -d '%'
But then I get:
xargs: insufficient space for argument
because the json element is too big, I'd assume. I'd prefer not write a bunch of files.

由于
@json永远不会产生任何换行，因此以下内容也可以工作：Demo on jq play
--join-output/-j按原样打印字符串，而不是打印生成以下内容的 JSON 字符串文字细绳。不添加任何换行符，甚至不添加尾随换行符。--raw-output/-r按原样打印字符串，而不是打印生成该字符串的 JSON 字符串文字。在每个字符串后添加换行符。"\\0"不会产生 NUL。您需要"\u0000"来实现这一点。<代码>。 | 没用。
'%'和%之间没有区别。它们都将%传递给xargs。-n 1没有用。-I隐含-L 1，这使得-n 1变得多余。{}比%更常用作替换表达式。但是%也可以，所以我没有改变它。Since
@jsonnever produces any line feeds, the following would also work:Demo on jq play
--join-output/-jprints the string as-is rather that rather than printing a JSON string literal that produces the string. Doesn't add any line feeds, not even a trailing one.--raw-output/-rprints the string as-is rather that rather than printing a JSON string literal that produces the string. Adds a line feed after each string."\\0"doesn't produce a NUL. You want"\u0000"for that.. |is useless.There's no difference between
'%'and%. They both pass%toxargs.-n 1is useless.-Iimplies-L 1, which renders-n 1redundant.{}is more commonly used as the replacement expression than%. But%is also fine, so I didn't change this.使用
--join-output（或-j）选项输出不带换行符的原始文本，并使用\u0000创建 <代码>NUL字符：Use the
--join-output(or-j) option to output raw text with no newlines, and use\u0000to create theNULcharacter:
