如何将批处理（CALL）命令的输出存储到变量 [英] How to store the output of batch (CALL) command to a variable

问题描述

我有批处理文件，它有命令调用 second.bat 文件。当它调用时它将产生单行输出。我想将该行存储为变量。

  CALL second.bat 
  pre> 
 
 
我尝试使用以下命令行，但没有使用
  FOR / Ftokens = * USEBACKQ%% F IN（'COMMAND'）do SET result = %% F 
 FOR / Ftokens = 1 delims =%% A IN DO SET NumDocs = %% A 
  
我不知道要用 COMMAND  
解决方案
正如帮助将告诉你， code>应该是你要运行的命令，并获得输出。所以在你的情况下 second.bat 。至少它适用于我：
  @echo off 
 FOR / Ftokens = *%% F IN （'second.cmd'）do SET result = %% F 
 echo％result％
  
注意，如果您使用'分隔命令，则不能使用 usebackq 选项。
 
I have the batch file which has the command to call second.bat file. It will produce single line of output when it called. I want to store that line into variable.
CALL second.bat
I have tried using the following lines of commands but no use
FOR /F "tokens=* USEBACKQ" %%F IN ('COMMAND') do SET result=%%F
FOR /F "tokens=1 delims= " %%A IN ('COMMAND') DO SET NumDocs=%%A
I don't know what to replace with COMMAND
解决方案
As the help will tell you, COMMAND should be the command you want to run and get the output of. So in your case second.bat. At least it works for me:
@echo off
FOR /F "tokens=*" %%F IN ('second.cmd') do SET result=%%F
echo %result%
Note that you cannot use the usebackq option if you're using ' to delimit your command.
