我寫了批處理腳本將CSS文件複製到某個目錄，問題是當我在目標目錄中打開CSS文件時，會刪除感嘆號。Windows批處理 - 延遲擴展刪除感嘆號
原來的CSS包含感嘆號如樣式：
.foo
{
color: pink !important;
}
我的CSS結果變得
.foo
{
color: pink important;
}
我看着這一現象的根本原因和依據：exclamation point being removed constantly in batch file
但我無法弄清楚我需要在哪裏禁用延遲擴展。
僅供參考，我的一批是做如下：
由逗號分隔每個主題串中，找到啓動和某些字符串相匹配的行號結束。
現在我有開始和結束行號（例如500和1000）
拷貝除了線500和1000
之間
定稿文件被複制到目的地目錄中的文件內容
請讓我知道，如果您需要更多的澄清，在此先感謝。

UPDATE
下面是我的解決方案，根據配置的建議。不同的是，按照說明， 在腳本開始處設置了EnableDelayedExpansion，以便對整個批處理作用域產生影響，然後僅在其應用的位置設置DisableDelayedExpansion。

禁用延遲擴展，在你的代碼段是沒有必要的。 – Endoro
這是必要的，因爲我有！名！它的CSS不能以其他方式轉換。 –
不能看到這一點。'filename'沒有內改變' resettheme'一旦它建立在開始，所以'％filename％'和'！filename！'應該是一樣的... – Magoo
