我打算編寫一個 shell 腳本（如果需要具體信息，它將在 Zsh 中執行），它將通過運行確定最新的 Vim 補丁：
git pull origin master
vernew=$(git describe --tags | sed 's/^v//;s/-/./g')
使用 Vim git 存儲庫的本地副本，將其與我當前安裝的 Vim 版本進行比較，如果兩者不同，它將修改我在開放構建服務 (OBS) 中的規範文件中定義的補丁級別Vim 儲存庫。為了能夠做到這一點，我需要知道如何將變數定義為等於目前安裝的 Vim 版本。將其定義為：
verold=$(vim --version)
vim --version至少對我來說，跑步不是一個選擇，回歸：

該輸出的第二行包含我感興趣的內容，補丁層級。但我不知道如何定義verold等於補丁等級。完整版本（即 7.4.1304）也是一個可接受的verold值，如果您知道如何給我這個值。
答案1
verold=$(vim --version |sed -n 's/^Included patches:\s1-*//p')
