我對 linux 很陌生，我不太了解排序。我需要按第 4 列然后按第 5 列對長檔案進行排序，忽略第一行。問題是，有兩個分隔符 - '.' 和 ',' - 我不知道如何使排序命令包含它們。我想它必須按第一行有“3”的列排序，然后在第二行按第二行有“5”的列排序。第二件事是我不知道如何保持第一行完整。值得注意的是，我無法將所有 ',' 更改為 '.'，它必須保持完整。而且我不能只洗掉帶有尾部或頭部的第一行，它必須保留。
這是正文：

我不確定我是否理解這個問題：為了按數字對第 4 列和第 5 列進行排序，您可以簡單地說：
sort -t, -k4,5 -n
-t,說使用逗號作為列分隔符-k4,5說要根據第 4 列和第 5 列進行排序-n說要按數字排序
評論：
- 就連字符而言：因為它不是排序列的一部分，為什么要費心呢？
- 就列標題而言：由于排序的型別，一個字母出現在任何數字的前面，所以列標題仍然是標題，那么為什么還要麻煩呢？
