您可以使用：
$ jq 'keys' file.json$ cat file.json:{ "Archiver-Version" : "Plexus Archiver", "Build-Id" : "", "Build-Jdk" : "1.7.0_07", "Build-Number" : "", "Build-Tag" : "", "Built-By" : "cporter", "Created-By" : "Apache Maven", "Implementation-Title" : "northstar", "Implementation-Vendor-Id" : "com.test.testPack", "Implementation-Version" : "testBox", "Manifest-Version" : "1.0", "appname" : "testApp", "build-date" : "02-03-2014-13:41", "version" : "testBox" }$ jq 'keys' file.json[ "Archiver-Version", "Build-Id", "Build-Jdk", "Build-Number", "Build-Tag", "Built-By", "Created-By", "Implementation-Title", "Implementation-Vendor-Id", "Implementation-Version", "Manifest-Version", "appname", "build-date", "version"]更新： 要使用这些键创建一个BASH数组：
使用BASH 4+：
mapfile -t arr < <(jq -r 'keys[]' ms.json)
在较旧的BASH上，您可以执行以下操作：
arr=()while IFS='' read -r line; do arr+=("$line")done < <(jq 'keys[]' ms.json)然后打印：
printf "%sn" ${arr[@]}"Archiver-Version""Build-Id""Build-Jdk""Build-Number""Build-Tag""Built-By""Created-By""Implementation-Title""Implementation-Vendor-Id""Implementation-Version""Manifest-Version""appname""build-date""version"
