Question

我正在编写此批处理文件。我需要将临时文件的内容分配给变量。我已经在同一个文件中完成了此操作，并且它可以正常工作，所以我不确定为什么它不起作用。

@echo off

rem set Microsoft Windows Version value to variable 
ver > myVersion.txt
set /p  compver = < myVersion.txt
del myVersion.txt

rem set computer hostname value to variable 
hostname > compName.txt
set /p myCompName = < compName.txt
del compName.txt

echo Hello %username%, you are currently logged into %myCompName%.
echo It is %time%, on %date%.
echo You are using a PC that is running %compver%

当我运行此批处理文件时，主机名确实会显示，但版本不会显示。

结果是：

Hello John, you are currently logged into JohnDoe.
it is 3:06:04:43, on Tue 12/11/2018
you are using a PC that is running .

我认为事情很复杂...您可以像下面的示例一样使用for /f来解析所需命令的输出：

@echo off

rem set Microsoft Windows Version value to variable 
for /f "delims=" %%A IN ('ver') do set "compver=%%A"

rem set computer hostname value to variable 
for /f "delims=" %%A IN ('hostname') do set "myCompName=%%A"

echo Hello %username%, you are currently logged into %myCompName%.
echo It is %time%, on %date%.
echo You are using a PC that is running %compver%
rem pause

使用delims=选项不拆分用''符号括起来的命令的输出。

批处理文件未将文件内容分配给变量
