Search for a string in command line output
提问by Ramesh
I want to search for the string "virtual" in "system model" attribute of 'sysinfo' command. The command should be successful if 'virtual' is found in the 'system model: -------------------------'i.e. output of the systeminfo. It should not search for 'virtual' in whole output of systeminfo command but should do in system model attribute only. For example the command
我想在“ sysinfo”命令的“ system model”属性中搜索字符串“ virtual” 。如果在“系统模型：-------------------------”即 systeminfo 的输出中找到“virtual”，则该命令应该会成功。它不应该在 systeminfo 命令的整个输出中搜索“virtual”，而应该只在系统模型属性中搜索。例如命令
systeminfo | findstr /i "system model"
I will get something like
我会得到类似的东西
System Model: HP Compaq dc7800p Small Form Factor
in the above line of the output i want to search for string virtual, and want to manipulate using errorlevel. So please help me to do this.
在上面的输出行中，我想搜索字符串 virtual，并想使用 errorlevel 进行操作。所以请帮助我做到这一点。
Following is the one I tried which was not correct. Or help me if i can use regular expressions
以下是我尝试过的不正确的一种。或者帮助我，如果我可以使用正则表达式
systeminfo | findstr /i /R "system model: virtual machine" > nul
if %errorlevel% == 0 (
echo virtual machine
) ELSE (
echo physical machine
)
Thanks in advance
提前致谢

Try this:
尝试这个：
systeminfo | findstr /I /B /C:"system model" | findstr /I "virtual"
if %errorlevel% == 0 (
echo virtual machine
) else (
echo real machine
)
I've tested in on a real and virtual system and it works fine on WinXp and Win7.
Note that the system modelstring is only used in English Windows versions. Windows versions in other languages will use a different names.
我已经在真实和虚拟系统上进行了测试，它在 WinXp 和 Win7 上运行良好。请注意，该system model字符串仅用于英文 Windows 版本。其他语言的 Windows 版本将使用不同的名称。
