Question

我正在尝试将find命令与if..else语句一起使用。我真正想要做的是在多个日志文件中搜索特定的字符串。如果找到该字符串，则要将该文件的名称附加“已通过”，否则将“失败”附加到另一个文本文件中。

我尝试了以下操作，但不起作用：

if (find /n /i "0 error" "filename.log") (
    echo "Passed" > log.txt
) else (
    echo "Failed" > log.txt
)

Answer 1

CMD /批处理不支持if语句中的命令。运行命令后，您需要评估错误级别（命令的退出代码）：

set "logfile=filename.log"
find /n /i "0 error" "%logfile%" >nul
if %errorlevel% equ 0 (
    >>log.txt echo %logfile% - Passed
) else (
    >>log.txt echo %logfile% - Failed
)

If I understand your question correctly:

To get a .txt file containing only the names of the logs in the current directory which contained 0 error:

FindStr /MIC:"0 Error" *.log>"Passed.txt"

If you wanted a log.txt to prodvide feedback on each log file in the current directory, instead…

From the Command Prompt:

(For %A In (*.log) Do @FindStr /MIC:"0 Error" "%A">Nul&&(@Echo %A Passed)||@Echo %A Failed)>"log.txt"

From a batch file:

@Echo Off
(For %%A In (*.log) Do FindStr /MIC:"0 Error" "%%A">Nul&&(
    Echo %%A Passed)||Echo %%A Failed)>"log.txt"

如何使用CMD将Find语句与'If / else语句'一起使用
