regex - 在批处理脚本中打印第二个标记之后的所有标记

Question

我正在寻找一种更简洁的方法来执行此操作。我很确定这是错误的，即使它有点管用。基本上我从文件 (temp.txt) 中获取这样的输出:

    Host Name:                 IBM-3J93A46MRS5
    OS Name:                   Microsoft Windows 7 Professional 
    OS Version:                6.1.7631 Service Pack 1 Build 7601
    OS Configuration:          Standalone Workstation
    Registered Owner:          IAMADMIN
    Original Install Date:     2011-12-15, 10:56:07 AM
    System Boot Time:          2013-05-27, 9:55:36 AM
    System Manufacturer:       DELL
    System Model:              4009BF7
    Time Zone:                 (UTC-05:00) Eastern Time (US & Canada)
    Total Physical Memory:     16,316 MB
    Available Physical Memory: 11,356 MB

并尝试将第二列数据放入变量中。取决于我愿不愿意。我正在使用 Findstr 进行筛选。

    @echo off
    setlocal enabledelayedexpansion

    systeminfo > temp.txt
    set "tmp_result_file=temp.txt"

    for /f "tokens=3-7 delims= " %%i in ('FINDSTR /C:"OS Name:" %tmp_result_file%') do set "OSNAME=%%i %%j %%k %%l"
    for /f "tokens=3-10 delims= " %%i in ('FINDSTR /V /C:"BIOS Version:" %tmp_result_file%^|FIND /I "OS Version:"') do set "OSVER=%%i %%j %%k %%l %%m %%n %%o %%p"
    for /f "tokens=4-7 delims= " %%i in ('FINDSTR /C:"Original Install Date:" %tmp_result_file%') do set "INSTDATE=%%i %%j %%k %%l"
    for /f "tokens=3-7 delims= " %%i in ('FINDSTR /C:"System Manufacturer:" %tmp_result_file%') do set "SYSMFG=%%i %%j %%k %%l"
    for /f "tokens=3-7 delims= " %%i in ('FINDSTR /C:"System Model:" %tmp_result_file%') do   set "SYSMDL=%%i %%j %%k %%l"

    echo.
    echo Operating System      : %OSNAME% , %OSVER% 
    echo Original Install Date : %INSTDATE%
    echo Model Information     : %SYSMFG% %SYSMDL% 

我不喜欢我如此精确地使用 token ，我只需要搜索值之后的所有内容。

不需要延迟扩展、临时文件或 FINDSTR，当然也不需要计算空格分隔的标记。您只需设置正确的 DELIMS 和 TOKENS 选项。第一个 FOR/F 处理 systeminfo 的输出并将每一行解析为名称和值。第二个 FOR/F 从每个值中去除前导空格。剩下的就是一系列 IF 语句来测试每个名称并适本地设置所需的变量。

@echo off
setlocal

for /f "delims=: tokens=1*" %%A in ('systeminfo') do (
  for /f "tokens=*" %%S in ("%%B") do (
    if "%%A"=="OS Name" set "OSNAME=%%S"
    if "%%A"=="OS Version" set "OSVER=%%S"
    if "%%A"=="Original Install Date" set "INSTDATE=%%S"
    if "%%A"=="System Manufacturer" set "SYSMFG=%%S"
    if "%%A"=="System Model" set "SYSMDL=%%S"
  )
)

echo(
echo Operating System      : %OSNAME%, %OSVER%
echo Original Install Date : %INSTDATE%
echo Model Information     : %SYSMFG% %SYSMDL%

如果您想捕获更多值，可能需要指定搜索字符串:使用字符串的变量名称对，并添加一些额外的 FOR 循环来处理每个测试，如下所示:

@echo off
setlocal

for /f "delims=: tokens=1*" %%A in ('systeminfo') do for %%S in (
  "OS Name:OSNAME"
  "OS Version:OSVER"
  "Original Install Date:INSTDATE"
  "System Manufacturer:SYSMFG"
  "System Model:SYSMDL"
) do for /f "delims=: tokens=1*" %%a in ("%%~S") do if %%A==%%a (
  for /f "tokens=*" %%s in ("%%B") do set "%%b=%%s"
)

echo(
echo Operating System      : %OSNAME%, %OSVER%
echo Original Install Date : %INSTDATE%
echo Model Information     : %SYSMFG% %SYSMDL%
