Grepping `reg query` result value?

问题

Consider the following result from a hypothetical reg query:

..>reg query HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MediaPlayer /v "I
nstallation Directory"

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MediaPlayer
    Installation Directory    REG_EXPAND_SZ    %ProgramFiles%\Windows Media Play
er

How do I grep the output so that I can assign the actual value of the setting (%ProgramFiles%\...) into a variable (or temp file)?

回答1:

example for batch files:

@FOR /F "tokens=2* " %%A IN ('reg query HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MediaPlayer /v "Installation Directory"') DO @SET PARAM=%%B 

If you want to use it directly in console - use single percent sign to denote variables (i.e. %A and %B)
