Find text in file and set it as a variable. Batch file
提问by byrqowy
I try to find one line in whole text file. Next I need to set this line as a variable.
我尝试在整个文本文件中找到一行。接下来我需要将此行设置为变量。
When i try do this:
当我尝试这样做时：
set MY_VARIABLE=findstr /I "MY_TEXT" MY.FILE
echo MY_VARIABLE
设置 MY_VARIABLE=findstr /I "MY_TEXT" MY.FILE
回声 MY_VARIABLE
the result of echo is "findstr /I "MY_TEXT" MY.FILE" i want to see result of "findstr /I "MY_TEXT" MY.FILE" not a command
echo 的结果是 "findstr /I "MY_TEXT" MY.FILE" 我想看到 "findstr /I "MY_TEXT" MY.FILE" 的结果而不是命令
when i try do this first enter in cmd
当我尝试这样做时，首先输入 cmd
for /F "delims=" %%a in ('findstr /I "MY_TEXT" MY.FILE') do set "batToolDir=%%a"
对于 /F "delims=" %%a in ('findstr /I "MY_TEXT" MY.FILE') 设置 "batToolDir=%%a"
second enter in cmd
第二次输入cmd
echo "%batToolDir%"
echo "%batToolDir%"
i see "the %%a variable is unsuspected"
我看到“ %%a 变量是出乎意料的”
when i make a file SCRIPT.bat
当我制作文件 SCRIPT.bat
@echo off
for /F "delims=" %%a in ('set MY_VARIABLE=findstr /I "MY_TEXT" MY.FILE') do set "batToolDir=%%a"
echo "%batToolDir%"
@回声关闭
对于 /F "delims=" %%a in ('set MY_VARIABLE=findstr /I "MY_TEXT" MY.FILE') 设置 "batToolDir=%%a"
echo "%batToolDir%"
i se anwser ""
我看到答案“”

Almost done
快完成了
For command line
对于命令行
for /F "delims=" %a in ('findstr /I "MY_TEXT" MY.FILE') do set "batToolDir=%a"
For batch file double the percent signs
对于批处理文件，将百分号加倍
for /F "delims=" %%a in ('findstr /I "MY_TEXT" MY.FILE') do set "batToolDir=%%a"
