如何添加，将只包含JSON列值

-1

#!/bin/bash 
# rsync using variables 
echo 'Id,Name,Amount,TS,unique_ID' > lfs.csv 
epoch=$(date +%s) 
u_id=0 

for ((id=1 ; ;id++)) 
do 
[[ $u_id == 100 ]] && ((u_id = 1)) || ((u_id +=1)) 

     echo $id",Danny_"$id","$id","$epoch","$u_id >> lfs.csv 
     sleep 

done

，我希望能够插入一列，将代表JSON数据：

{ 
    "totalMemory" : 12206567424, 
    "totalProcessors" : 4, 
    "version" : "0.4.1", 
    "startTime" : 1494851008421, 
    "agent" : { 
    "reconnectRetrySec" : 5, 
    "agentName" : "1002", 
    "checkRecovery" : false, 
    "backPressure" : 10000, 
    "throttler" : 100 
    }, 
    "logPath" : "/eq/equalum/eqagent-0.4.1.0-SNAPSHOT/logs", 
    "status" : { 
    "current" : "active", 
    "currentMessage" : null, 
    "previous" : "pending", 
    "previousMessage" : "Recovery:Starting pipelines" 
    }, 
    "autoStart" : false, 
    "recovery" : { 
    "agentName" : "1002", 
    "partitionInfo" : { }, 
    "topicToInitialCapturePosition" : { } 
    }, 
    "sources" : [ ], 
    "upTime" : "5 min, 26 sec", 
    "build" : "0-SNAPSHOT", 
    "target" : { 
    "targetType" : "equalum", 
    "agentID" : 1002, 
    "engineServers" : "<some_info>", 
    "kafkaOptions" : null, 
    "eventsServers" : "<some_info>", 
    "jaasConfigurationPath" : null, 
    "securityProtocol" : "PLAINTEXT", 
    "stateMonitorTopic" : "_state_change", 
    "targetType" : "equalum", 
    "status" : { 
     "current" : "active", 
     "currentMessage" : null, 
     "previous" : "pending", 
     "previousMessage" : "Recovery:Starting pipelines" 
    }, 
    "serializationFormat" : "avroBinary" 
    } 
}

和我想添加另一列代表JSON列并将包含上面的JSON字符串。我想过如何添加列，但我的主要目的是将JSOn字符串插入到列中，我将其用作本地文件系统。

使用JSON解析器写道。 – 123

你能举个例子吗？ – ErezN

网站上有数百个。 – 123

您可以用urlencode例如具有这种功能的另一种回答

url_encoder() { (
    LC_ALL=C 
    for ((i=0;i<${#str};i+=1)); do 
     c=${str:i:1} 
     if [[ $c = [-_./a-zA-Z0-9] ]]; then 
      echo -n "${c}" 
     elif [[ $c = [$'\1'-$'\x7f'] ]]; then 
      printf '%%%02X' "'$c" 
     else 
      printf '%%%s' $(echo -n "$c" | od -An -tx1) 
     fi 
    done 
)} 

echo "$id,Danny_$id,$id,$epoch,$u_id,$(url_encoder "$your_data")" >> lfs.csv

或更有效地

# urlencode 
perl -MURI::Escape -e 'print uri_escape shift' "$your_data" 

# urldecode 
perl -MURI::Escape -e 'print uri_unescape shift' "$your_data"
