正確格式化 CSV 文件，以便正確地從 CSV 中獲取數據

我有一個 CSV 文件，如下所示：

我想INITIAL OFFER從這個文件中刪除“”塊並只保留“ FINAL OFFER”塊我還想從第一個欄位中刪除逗號（，）並從最後一列中刪除多餘的空格，以便更輕鬆地搜尋這些列.

如果您使用管道作為分隔符，則可以awk根據欄位數輕鬆過濾數據，例如：

awk -F'|' 'NF==2 { f=1 } NF==1 { f=0 } f' infile

打高爾夫球：

awk -F\| 'NF==1{f=0}NF==2{f=1}f'

sed -e '/FINAL OFFER/p;/INITIAL OFFER/,/FINAL OFFER/ d' input.csv  > output.csv

這將再次列印 FINAL OFFER 行，因為它即將被/INITIAL OFFER/,/FINAL OFFER/範圍刪除。
