如何通过bash脚本过滤带有{}大括号的文本

Question

如果要从代码源代码块中获取connection_resource_type = "*“，则包含一个源代码= connection_resource_type = "cosmosdb-SQL"

Main.tf

      module "network-security-group" {
      source          = "git@github.com:test/terraform-azure-network-security-group.git?ref=v3.1.1"
      subscription_id = var.subscription_id
      resource_group  = var.resource_group
      resource_name   = local.nsg_name
      security_rules  = var.security_rules
      context         = var.context
    }
   module "tf_azure_private_endpoint_sean125" {
  source                       = "git@github.com:***/terraform-azure-utils.git//private-endpoint?ref=***"
  subscription_id              = "ed6d71e6-0262-49ad-b8ff-074000058889"
  depends_on                   = []
  connection_resource_type     = "cosmosdb-SQL"
  resource_name                = ""
  pgi_private_endpoint_enabled = "false"
  enable_private_endpoint      = "false"
  connection_resource_id       = "wefew"
  resource_group               = "AZ-RG-Sean-Demo-01"
  resource_tags = {
    Application_Id               = "CI002489694"
    Application_Name             = "Demo"
    Billing_Notification_Group   = ""
    Cost_Center                  = "1076015162"
    Original_Requestor           = "***"
    Owner_Notification_Group     = ""
    Owning_Role                  = null
    Security_Notification_Group  = ""
    Stage                        = "Dev"
    Technical_Notification_Group = ""
    WBS_Element                  = null
    terraform_managed            = "true"
  }

bashscript.sh

#!/bin/bash
arr=()
a=`cat main.tf`
for i in $a
do   
    
   az=$(sed 's/^[^{]*{\([^{}]*\)}.*/\1/' main.tf)
   if [[ $i == "key-vault            = true"]]
   then
       

   echo $i
   

   if [[  $line == *"key-vault            = true"*  ]]
   then
            echo $line
            az=$(sed 's/^[^{]*{\([^{}]*\)}.*/\1/' main.tf)
   fi
   
done

cat main.tf | sed 's/^}$/||/' | tr '\n' ' ' | sed 's/||/}\n/g' | grep -Eo 'source\s+=\s+.*key-vault\s+=\s+true' | grep -Eo 'source\s+=\s+"[[:alnum:][:punct:]]+"\s'
