Question

底部是一些示例json数据，我想添加时间戳。即"time": "1544785866.176123088"时间戳在每次迭代中都必须是唯一的，并且需要出现在“ bladesetName”上方的行上。不幸的是，到目前为止，我没有用。将时间打印到所需位置的文件后，我将为每个条目添加1ns。有更好的方法吗？

timestamp() {
    date +%s.%N
}

awk "/bladesetName/{ print '"time" "$(timestamp)"' }1" volumes3.json

这会引发错误

awk: /bladesetName/{ print 'time 1544786158.644385726' }1
awk:                       ^ invalid char ''' in expression

。

这是一种使用jq的方法：

def addnow: 
  . as $in
  | to_entries
  | (map(.key)|index("bladesetName")) as $i
  | if $i 
    then .[0:$i]+[{key:"time",value:now}]+.[$i:] | from_entries
    else $in 
    end ;

walk(if type=="object" then addnow else . end)

如果您确实希望将时间作为字符串，只需添加tostring，就像在(now|tostring)中一样

如果您的jq没有walk，那么现在是升级的好时机；否则，只需复制并粘贴其def，就可以轻松在网上找到它，例如通过谷歌搜索：jq“ def walk”

在字符串前一行打印时间戳功能的结果
