Json使用jq来解析，读取，如果找到条目则返回true
抱歉，如果这是基本的，但 jq 的文档不太好 我有这个 json：
{
"jsonrpc": "2.0",
"result": [{
"hostid": "10084",
"host": "Zabbix server",
"interfaces": [{
"interfaceid": "1",
"ip": "127.0.0.1"
}]
}, {
"hostid": "10336",
"host": "AUTO",
"interfaces": [{
"interfaceid": "4",
"ip": "1.2.3.4"
}]
}, {
"hostid": "10337",
"host": "AUTOSERVER",
"interfaces": [{
"interfaceid": "5",
"ip": "4.5.6.7"
}]
}, {
"hostid": "10348",
"host": "Server00001",
"interfaces": [{
"interfaceid": "16",
"ip": "4.5.6.7"
}]
}],
"id": 2
}
我需要找到一种方法来使用 jq 来查找其中一台主机中是否存在“Server0001” 我知道我可以使用 grep 但我更喜欢在这里使用 jq，比如 select.. 任何帮助或参考好的文档将不胜感激
Apologies if this is basic but the doc for jq is not so good
i have this json:
{
"jsonrpc": "2.0",
"result": [{
"hostid": "10084",
"host": "Zabbix server",
"interfaces": [{
"interfaceid": "1",
"ip": "127.0.0.1"
}]
}, {
"hostid": "10336",
"host": "AUTO",
"interfaces": [{
"interfaceid": "4",
"ip": "1.2.3.4"
}]
}, {
"hostid": "10337",
"host": "AUTOSERVER",
"interfaces": [{
"interfaceid": "5",
"ip": "4.5.6.7"
}]
}, {
"hostid": "10348",
"host": "Server00001",
"interfaces": [{
"interfaceid": "16",
"ip": "4.5.6.7"
}]
}],
"id": 2
}
i need to find a way to use jq to find if "Server0001" exists in one of the hosts
i know i can use grep but i prefer using jq here, like select..
any help or ref toa good doc would be much appriciated

任何（请参阅manual) 如果条件与至少一项匹配，则可以返回布尔值。演示

您可能还想在调用
jq时使用一些参数（请参阅manual)：--arg选项，例如，允许您添加一个可以从过滤器字符串外部初始化的变量。使用-e（或--exit-status）标志，您可以让jq根据过滤器的最终结果设置退出状态。总之，这使您能够像这样使用jq：any(see the manual) can return a boolean value if a condition matches with at least one item.Demo

You may also want to use the some parameters when invoking
jq(see the manual): The--argoption, for instance, lets you add a variable which can be initialized from outside the filter string. And with the-e(or--exit-status) flag you can havejqset the exit status according to the filter's final result. Together, this enables you to usejqlike this:
