AWK / SED附加到日志文件

Question

我有一個運行的qpid命令，它為我提供了漂亮的墊子打印效果，如下所示：

{
"value": {
    "application": {
        "connectionState": "Disconnected",
        "connectionTime": "No connection was established",
        "linkAttributes": {
            "ackSettings": {
                "dataAckEnabled": "true",
                "dataAckTimeout": "5000",
                "dataNakRetryLimit": "0",
                "retransmitDelay": "500"
            },
            "keepAliveSettings": {
                "keepAliveAckTimeout": "5000",
                "keepAliveInterval": "30000"
            },
            "logTraffic": "false",
            "port": "9999",
            "role": "server"
        },
        "protocol": "Class"
    }
},
"queueStats": {}

我將得到此輸出，並去除引號和方括號，然后使用以下命令將其附加到日志文件中：

command | sed 's/"//g'  | sed 's/{//g' | sed 's/}//g' | sed -e 's/$/\r/g' |awk '!/""/{ORS=(/},/?RS:""); gsub(/[[:blank:]]+/,""); sub(/}$/,"},\n"); print}' |awk '{gsub(/\\n/,"\n")}1' >> app.log

結果如下：

  ^M^M^MendpointApplications:^MApplicationSide:^MconnectionState:Disconnected,^MconnectionTime:Noconnectionwasestablished,^MlinkAttributes:^MackSettings:^MdataAckEnabled:true,^MdataAckTimeout:5000,^MdataNakRetryLimit:0,^MretransmitDelay:500^M,^MkeepAliveSettings:^MkeepAliveAckTimeout:5000,^MkeepAliveInterval:30000^M,^MlogTraffic:false,^Mport:9999,^Mrole:server^M,^Mprotocol:ClassD^M^M,^MqueueStats:^M

每次要將輸出追加到新行中的日志時，如何擺脫^ M個字符？

我的預期結果將是：

    endpointApplications:ApplicationSide:connectionState:Disconnected,connectionTime:Noconnectionwasestablished,linkAttributes:ackSettings:dataAckEnabled:true,dataAckTimeout:5000,dataNakRetryLimit:0,retransmitDelay:500,keepAliveSettings:keepAliveAckTimeout:5000,keepAliveInterval:30000,logTraffic:false,port:9999,role:server,protocol:ClassD,queueStats:

基本上，結果與以前相同，但是沒有^ M個字符，我想每次將命令的結果附加到一個新的石灰上。

您的sed命令s/$/\\r/正在注入它們。 只是不要那樣做！
