+#!/usr/bin/env sh
+#
+# 这个脚本用于一键提交并推送当前 Git 仓库。
+#
+# 使用命令案例：
+#   sh push-git.sh "提交说明"
+#   chmod +x push-git.sh && ./push-git.sh "提交说明"
+#   ./push-git.sh -m "提交说明" --pull-rebase
+#   ./push-git.sh -m "提交说明" --dry-run
+#
+# 这个脚本做的事情：
+# 1. 自动进入脚本所在 Git 仓库根目录，并检查当前分支和远程仓库。
+# 2. 如果存在本地改动，执行 git add -A 和 git commit -m "提交说明"。
+# 3. 按当前分支推送到远程仓库；首次推送会自动设置 upstream。
