搜索和從輸出到匹配模式的文件

Question

想寫AWS雲的形成腳本安全組內更換，這個過程太很重複我嘗試了一些黑客將其自動化

我有CSV輸出從下面的調用awk和sed：

awk -F, 'NR > 1 { OFS=",";print $2, $3, $4, $5 }' para.csv | sed -n 1p 

輸出：

10.0.0.0/8,tcp,53,53 

我需要這個輸出映射到FIL Ë其具有以下

"ingress5": { 
     "Type": "AWS::EC2::SecurityGroupIngress", 
     "Properties": { 
     "GroupId": { 
      "Ref": "sginformatica" 
     }, 
     "IpProtocol": "", 
     "FromPort": "", 
     "ToPort": "", 
     "CidrIp": "" 
     } 
}, 

即，從命令IpProtocol的輸出應該被映射到tcp。

FromPort應映射53（第3列，或在輸出字段3）

ToPort應映射53（第4列，或在輸出字段4）

CidrIp應該被映射到10.0.0.0/8（場輸出的1）

Answer 1

#!/bin/bash 

while IFS="," read -r CidrIp IpProtocol FromPort ToPort; do 
cat << EOF 
"ingress5": { 
     "Type": "AWS::EC2::SecurityGroupIngress", 
     "Properties": { 
     "GroupId": { 
      "Ref": "sginformatica" 
     }, 
     "IpProtocol": "$IpProtocol", 
     "FromPort": "$FromPort", 
     "ToPort": "$ToPort", 
     "CidrIp": "$CidrIp" 
     } 
}, 
EOF 
done < file 

利用該文件：

 
10.0.0.0/8,tcp,53,53 

輸出：

 
"ingress5": { 
     "Type": "AWS::EC2::SecurityGroupIngress", 
     "Properties": { 
     "GroupId": { 
      "Ref": "sginformatica" 
     }, 
     "IpProtocol": "tcp", 
     "FromPort": "53", 
     "ToPort": "53", 
     "CidrIp": "10.0.0.0/8" 
     } 
}, 

---

或沒有文件：

awk -F, 'NR > 1 { OFS=",";print $2, $3, $4, $5 }' para.csv | sed -n 1p | while ...; do ...; done 

Answer 2

安裝和使用靈活的命令行JSON處理器 - jq

比方說，我們有ingress.json文件內容：

{ 
    "ingress5": { 
     "Type": "AWS::EC2::SecurityGroupIngress", 
     "Properties": { 
     "GroupId": { 
      "Ref": "sginformatica" 
     }, 
     "IpProtocol": "", 
     "FromPort": "", 
     "ToPort": "", 
     "CidrIp": "" 
     } 
    } 
} 

起初，我們會調整的關鍵輸入字符串看作是一個有效的JSON字符串：

v="["$(awk -F, '{ OFS=",";print "\042"$2"\042", "\042"$3"\042", $4, $5 }' para.csv | sed -n 1p)"]" 
echo $v 
["10.0.0.0/8","tcp",53,53] 

下一步是修改使用JQ命令所需的屬性值：

jq --argjson v "$v" '.ingress5.Properties.IpProtocol = $v[1] | .ingress5.Properties.FromPort = $v[2] 
    | .ingress5.Properties.ToPort = $v[3] | .ingress5.Properties.CidrIp = $v[0]' ingress.json 

輸出：

{ 
    "ingress5": { 
    "Type": "AWS::EC2::SecurityGroupIngress", 
    "Properties": { 
     "GroupId": { 
     "Ref": "sginformatica" 
     }, 
     "IpProtocol": "tcp", 
     "FromPort": 53, 
     "ToPort": 53, 
     "CidrIp": "10.0.0.0/8" 
    } 
    } 
}
