Question

我想读取一个文本文件并在该文本文件内找到一个字符串。如果存在搜索字符串，则需要使用errorcode 1退出批处理。

示例：

Text inside a txt file would be like (123;345;678;abc)
i need to search the string / numeric value (abc or 123)

如果找到，则批处理应返回1。

Answer 1

According to find, you should be able to perform it like this:

find "myTextToSearch" C:\\Path\\To\\File.txt

But, like you can see in documentation, these are the exit status:

Errorlevel

FIND will return an ErrorLevel as follows:

0 String found in at least one of the files.

1 String not found

2 If any files in the list do not exist or if no files match a wildcard mask.

An invalid switch is given.

So either you should consider 0 (matching OK), instead of 1, either you should add post instruction to convert the status like you want.

Let me know if you need further information.

Answer 2

如果文本文件包含abc和/或123，然后以1退出，对吗？

findstr "abc 123" file.txt && (exit /b 1) || (exit /b 0)

findstr返回0（如果找到了字符串（“成功”），则返回1（如果没有找到字符串（“ Fail”））（与您完全一样）需要它）。如果您可以将0用于“找到”，将1用于“找不到”：

findstr "abc 123" file.txt
exit /b %errorlevel%

批处理文件以读取文本文件并搜索字符串。如果找到字符串，则返回错误代码1
