# LFS Pre-Push Hook — push 前显示 LFS 文件清单并要求确认
|
||||||
|
# Issue: OS-GBL-F-002
|
||||||
|
#
|
||||||
|
# 功能：
|
||||||
|
# 1. 检测本次 push 涉及的 LFS 文件，显示清单和总大小
|
||||||
|
# 2. >500MB 的文件标记警告
|
||||||
|
# 3. 用户确认后执行 git lfs pre-push 上传
|
||||||
|
#
|
||||||
|
# 环境变量：
|
||||||
|
# LFS_PREPUSH_SKIP=1 跳过确认（CI/CD 用）
|
||||||
|
#
|
||||||
|
# 兼容性：POSIX sh + BSD awk（macOS 原生环境）
