台灣身份證字號驗證 (Shell Script)

Install

• 安裝至 local
  1. wget -q -O /usr/local/bin/verify https://git.io/DL
  2. chmod 755 /usr/local/bin/verify
• 直接使用
  1. wget -q -O verify.sh https://git.io/DL
  2. chmod +x verify.sh

Usage

1. 驗證單一號碼 verify A123456789
2. 驗證大量號碼 cat FILE FILE2 FILE3 |xjobs -j32 -v0 verify 僅顯示錯誤號碼
