将变量设置为批处理文件中“查找”的结果

I would like to set a variable based on the number of lines in a file that contain a give string.

我想根据文件中包含给定字符串的行数设置变量。

Something like:

set isComplete = 0
%isComplete% = find /c /i "Transfer Complete" "C:\ftp.LOG"
IF %isComplete% > 0 ECHO "Success" ELSE ECHO "Failure"

Or:

set isComplete = 0
find /c /i "Transfer Complete" "C:\ftp.LOG" | %isComplete%
IF %isComplete% > 0 ECHO "Success" ELSE ECHO "Failure"

Neither of those options work, obviously.

显然,这些选项都不起作用。

Thanks.

#1

from the command line

从命令行

for /f "tokens=3" %f in ('find /c /i "Transfer Complete" "C:\ftp.LOG"') do set isComplete=%f

from the batch script

从批处理脚本

for /f "tokens=3" %%f in ('find /c /i "Transfer Complete" "C:\ftp.LOG"') do set isComplete=%%f

You don't need to use the for command; find will set the ERRORLEVEL to one of these values, based on the result:

您不需要使用for命令; find将根据结果将ERRORLEVEL设置为以下值之一:

0, At least one match was found.

0,找到至少一个匹配。

1, no matches were found.

1,未找到匹配项。

2 or more, an error occurred.

2或更多,发生错误。

Since it looks like you just want to see if the transfer completed, and not the total count of times the string appears, you can do something like this:

由于看起来您只想查看传输是否已完成,而不是字符串出现的总次数,您可以执行以下操作:

@echo OFF

@find /c /i "Transfer Complete" "C:\test path\ftp.LOG" > NUL
if %ERRORLEVEL% EQU 0 (
    @echo Success
) else (
    @echo Failure
)
