读取批处理文件中具有空间的注册表项？

Question

I want to read the registry key which has space in it. If I read, how can I skip the REG_SZ in the output.

I tried

FOR /F "tokens=*" %%A IN ('%SystemRoot%\system32\REG.exe QUERY "HKLM\SOFTWARE\Wow6432Node\PostgreSQL\Installations\postgresql-9.0" /v "Base Directory"  ^| find /i "REG_SZ"') DO set pghome=%%B
echo %pghome% 
cd /d %pghome%

Output is

C:\Users\test>set pghome=%B
C:\Users\test>echo %B
%B
C:\Users\test>cd /d %B
The system cannot find the path specified.

How can I read the path from the registry and navigate to it

If you are reading the line with the required value filtering for the REG_SZ , you will get a line as (sorry i've not postgresql to test)

Base Directory    REG_SZ    C:\ProgramFiles\ .....

Since for /f command is by default using spaces (and more characters) as separators, what you have is a line with, at least, 4 tokens: Base , Directory , REG_SZ , C:\\... and if the value contains spaces, aditional tokens will be available.

What is needed is all information from 4th and following tokens, so the better option will be

for /f "tokens=3,*" %%a in ....

That way, %%a will hold REG_SZ and %%b the rest of the line.
