Assume I want to execute a command like the following from within a DOS batch script:

for /F "Tokens= Usebackq" %%G in (' "D:\some\path\with blanks inside\myprog.exe" -p "......" %1') do set "....."

then I get an error like:

'D:\some\path\with' is not recognized as an internal or external command,operable program or batch file.

When I put myprog,.exe into a directory without blanks everything work.
However I prefer to have a path WITH blanks.

How can I get the command working anyway?
How can I mask the blanks?
Mind the single quote after opening bracket which should enclose all inner double quotes (from my point of view)

Similar question:

What if I want to put the path to program into a variable. The following does not work:

set pathtoprog=D:\some\path\with blanks inside
for /F "Tokens= Usebackq" %%G in (' "%pathtoprog%\myprog.exe" -p "......" %1') do set "....."

How can I code this successfully?

Actually USEBACKQ makes only sense if you want to read a file. The way you used it for processing the output of an application is just wrong. Steffen

Sorry, same problem with your suggestion

Are you absolutely sure that you don't have a typo in the path?

Steffen

Yes, 1000%.
I copied again the whole path from File Explorer into batch script
...same error.

And I verified it in another way:

if I eliminate the blank in path in File Explorer folder name and in script variable assignment
.... it works

I feel like I've seen this before and I had to in order to actually get it working but I can't find where I used it

works

thank you

An extra set of escaped double quotes would have done the trick.

Escaping the quotes shouldn't be necessary:

Escaping the quotes shouldn't be necessary:

Code: Select all

for /f delims^= %%g in ('""D:\some\path\with blanks inside\myprog.exe" -p "......" %1"') do set "....."

We have a discussion about it here on DosTips. I will see if I can dig up that thread.

I've answered myself - those escaped quotes lose their semantics, but preserve their syntactic meaning; that is, the path within the command will be quoted properly, preventing metacharacters from wreaking havoc.

So the following won't work.
But this will:
