我正在嘗試使批處理腳本在文本檔案中以自己的行輸出每個資料包 ASCII。我正在使用帶有 tshark 和 awk 的 Windows 命令提示符。
批處理看起來像這樣。我想要下面的腳本
@ECHO OFF
tshark -r "PCAP" --hexdump delimit | awk -f "awk script" >> "txt file path"
來自 tshark 的輸出

我會AWK按照以下方式利用 GNU 來完成這項任務，讓file.txt內容成為

給出輸出

說明：我通知 GNUAWK輸出行分隔符 ( ORS) 是空字串，因此在printing 時沒有追加任何內容，然后對于每一行，我使用substr函式獲取$0從第 57 個字符和print它開始的整行 ( ) 的子字串。如果您想了解更多資訊ORS，請閱讀8 個強大的 Awk 內置變數 - FS、OFS、RS、ORS、NR、NF、FILENAME、FNR
（在 gawk 4.2.1 中測驗）
