CSVファイルからyamlテンプレートを作成する

私の変数を使ってテンプレートからyamlファイルを作成しようとしています。私のyamlテンプレートは次のとおりです

number: {{NUMBER}}
  name: {{NAME}}
  region: {{REGION}}
  storenum: {{STORENUM}}
  clients: {{CLIENTS}}
  tags: {{TAGS}}


storename: {{STORENAME}}
employee: {{EMPLOYEE}}
products: {{PRODUCTS}}

しかし、私の変数はCSVファイルにあります。構造は変数です。

Number - Name - Region - Storenum  
StoreX - StoreX - New York - 30  

これで、可変パラメータを持つテンプレートから生成される小さなスクリプトが作成され、テンプレートは次のようになりますscript.sh template.yml -f variables.txt。私の結果は次のとおりです

number: 37579922
  name: Store1
  region: New York
  storenum: 32
  clients: 100
  tags: stores


storename: Store newyork
employee: 10
products: 200

しかし、一度に1つしかできません。 CSVパラメータを読み取ってプログラムに送信して、たとえばTemplate1,Template2,etcCSVパラメータで生成する方法はありますか？

#!/bin/bash
readonly PROGNAME=$(basename $0)

config_file="<none>"
print_only="false"
silent="false"

usage="${PROGNAME} [-h] [-d] [-f] [-s] -- 

where:
    -h, --help
        Show this help text
    -p, --print
        Don't do anything, just print the result of the variable expansion(s)
    -f, --file
        Specify a file to read variables from
    -s, --silent
        Don't print warning messages (for example if no variables are found)

examples:
    VAR1=Something VAR2=1.2.3 ${PROGNAME} test.txt 
    ${PROGNAME} test.txt -f my-variables.txt
    ${PROGNAME} test.txt -f my-variables.txt > new-test.txt"
