首先要注意几点:当你使用 Data/data1.txt 作为参数时，它真的应该是 /Data/data1.txt(带前导斜线)?另外，外循环应该只扫描 .txt 文件，还是/Data 中的所有文件?这是一个答案，假设只有 /Data/data1.txt 和 .txt 文件:

A couple of notes first: when you use Data/data1.txt as an argument, should it really be /Data/data1.txt (with a leading slash)? Also, should the outer loop scan only for .txt files, or all files in /Data? Here's an answer, assuming /Data/data1.txt and .txt files only:

#!/bin/bash
for filename in /Data/*.txt; do
    for ((i=0; i<=3; i++)); do
        ./MyProgram.exe "$filename" "Logs/$(basename "$filename" .txt)_Log$i.txt"
    done
done

注意事项:

• /Data/*.txt 扩展为/Data 中文本文件的路径(包括/Data/部分)
• $( ... ) 运行一个 shell 命令并将其输出插入命令行中的那个点
• basename somepath .txt 输出 somepath 的基本部分，从末尾删除 .txt(例如 /Data/file.txt -> file)

• /Data/*.txt expands to the paths of the text files in /Data (including the /Data/ part)
• $( ... ) runs a shell command and inserts its output at that point in the command line
• basename somepath .txt outputs the base part of somepath, with .txt removed from the end (e.g. /Data/file.txt -> file)

如果您需要使用 Data/file.txt 而不是 /Data/file.txt 运行 MyProgram，请使用 "${filename#/}" 删除前导斜杠.另一方面，如果你真的想扫描Data而不是/Data，只需使用作为Data/*.txt中的文件名.

If you needed to run MyProgram with Data/file.txt instead of /Data/file.txt, use "${filename#/}" to remove the leading slash. On the other hand, if it's really Data not /Data you want to scan, just use for filename in Data/*.txt.
