jq: output array of json objects
BashJqBash Problem Overview
Say I have the input:
{
"name": "John",
"email": "[email protected]"
}
{
"name": "Brad",
"email": "[email protected]"
}
How do I get the output:
[
{
"name": "John",
"email": "[email protected]"
},
{
"name": "Brad",
"email": "[email protected]"
}
]
I tried both:
jq '[. | {name, email}]'
and
jq '. | [{name, email}]'
which both gave me the output
[ { "name": "John", "email": "[email protected]" }]
[ { "name": "Brad", "email": "[email protected]" }]
I also saw no options for an array output in the documentations, any help appreciated

Use slurp mode:

$ jq -s '.' < tmp.json
[
{
"name": "John",
"email": "[email protected]"
},
{
"name": "Brad",
"email": "[email protected]"
}
]
