# jiu-gencode.sh — 平台方在 EC2 上批量生成兑换券（激活码）的便捷封装。
#
# 自动读取 /opt/jiu/config/production.env 的数据库连接，调用同目录的
# jiu-gencode 二进制写入码池 license_codes。随 server 发版部署到
# /opt/jiu/backend/，无需再本地交叉编译 + scp。
#
# 远程一行用法（在你的 Mac 上）：
#   ssh -i ~/.ssh/wangjia.pem ec2-user@18.136.60.128 \
#     '/opt/jiu/backend/jiu-gencode.sh -type annual -days 365 -count 100 -batch 2026-summer'
#   ssh -i ~/.ssh/wangjia.pem ec2-user@18.136.60.128 \
#     '/opt/jiu/backend/jiu-gencode.sh -type trial -days 7 -count 1'
#
# 参数透传给 jiu-gencode：-type trial|monthly|annual|lifetime  -days N(0=永久)
#   -devices N(0=不改门店现值)  -count N  -batch <批次>  -note <备注>
