我打算编写一个 shell 脚本（如果需要具体信息，它将在 Zsh 中执行），它将通过运行确定最新的 Vim 补丁：
git pull origin master
vernew=$(git describe --tags | sed 's/^v//;s/-/./g')
使用 Vim git 存储库的本地副本，将其与我当前安装的 Vim 版本进行比较，如果两者不同，它将修改我在开放构建服务 (OBS) 中的规范文件中定义的补丁级别Vim 存储库。为了能够做到这一点，我需要知道如何将变量定义为等于当前安装的 Vim 版本。将其定义为：
verold=$(vim --version)
vim --version至少对我来说，跑步不是一个选择，返回：

该输出的第二行包含我感兴趣的内容，补丁级别。但我不知道如何定义verold等于补丁级别。完整版本（即 7.4.1304）也是一个可接受的verold值，如果您知道如何给我这个值。
答案1
verold=$(vim --version |sed -n 's/^Included patches:\s1-*//p')
