直接写入【推荐】

# 提交在web目录下处理打印版本信息
printVersion() {
    cd ${curDir}
    echo "==================================printVersion===================================="
    curBranch=$(git show-ref | grep $(git log --pretty=%h -1) | sed 's|.*/\(.*\)|\1|' | sort -u | grep -v HEAD)
    commitID=$(git rev-parse --short HEAD)
    commitTime=$(git show --pretty=format:"%ci" | head -1)
    buildTime=$(date "+%Y-%m-%d %H:%M:%S")
    echo "{
    \"version\":{
        \"curBranch\": \"$curBranch\",
        \"commitID\": \"$commitID\",
        \"commitTime\": \"$commitTime\"
    },
    \"buildCfg\":{
        \"buildTime\": \"$buildTime\",
        \"envName\":\"$envName\",
        \"isPro\":$isPro,
        \"defaultLang\":$defaultLang,
        \"isHideLang\":$isHideLang,
        \"isTokenAuth\":$isTokenAuth
    }
}" > $versionDist
    echo "=====版本记录生产version.json成功========"
    cat $versionDist
}

生成后的数据：

{
  "version": {
    "curBranch": "1.1.1",
    "commitID": "9431f49",
    "commitTime": "2022-01-13 17:48:26 +0800"
  },
  "buildCfg": {
    "buildTime": "2022-01-13 18:45:22",
    "envName": ".env.defaultCookie",
    "isPro": true,
    "defaultLang": "zh",
    "isHideLang": false,
    "isTokenAuth": false
  }
}

动态替换

#!/bin/bash
>r.json

# echo '{' >>r.json
for i in ${!s_arr[@]}; do

  var2=${s2_arr[$i]}
  #     sed  's/var1/$var1/g' $template | sed 's/var2/$var2/g'>>r.txt
  echo $template | sed "s/var1/$var1/g" | sed "s/var2/$var2/g" >>r.json
done
# echo '}' >>r.json

生成后的数据：

{"name":"衬衫","value":5},
{"name":"羊毛衫","value": 20},
{"name":"雪纺衫","value": 36},
{"name":"裤子","value": 10},
{"name":"高跟鞋","value": 10},
