For /f loop findstr problem The batch script finds nothing !!!

"C:\Program Files\7-Zip\7z.exe" h -scrcsha256 "Test.7z" output:

SHA256 Size Name

SHA256 for data: 1D29A48C53E20F5E854FA67A81FFAD7366DF42E507D319CC41FF21E7DE4A4DBC

Everything is Ok

Code: Select all

"C:\Program Files\7-Zip\7z.exe" h -scrcsha256 "Test.7z" | findstr /c:"SHA256 for data"

A command launched from the command line finds this

SHA256 for data: 1D29A48C53E20F5E854FA67A81FFAD7366DF42E507D319CC41FF21E7DE4A4DBC

Code: Select all

for /f "skip=1 tokens=* usebackq" %%a in (`^""C:\Program Files\7-Zip\7z.exe" h -scrcsha256 "Test.7z" ^| findstr "SHA256 for data"^"`) do echo %%a

The batch script finds nothing !!!!

Please help me

I didn't test it yet, but, Perhpas you need to add the command Pause if you execute it by double click ?

Code: Select all

for /f "skip=1 tokens=* usebackq" %%a in (`^""C:\Program Files\7-Zip\7z.exe" h -scrcsha256 "Test.7z" ^| findstr "SHA256 for data"^"`) do echo %%a
pause

Here is another way to get HASH into a variable in batch if you want to use it later :

Code: Select all

@echo off
for /f "tokens=1 usebackq" %%a in (`^""C:\Program Files\7-Zip\7z.exe" h -scrcsha256 "Test.7z" ^| findstr "Test.7z"^"`) do ( 
	set "HASH=%%a"
)
echo %HASH%
pause

I tested that batch code and it works?!

Maybe you wanted to add a "/c:" (without doublequotes) like in the sniplet above that for loop:

Code: Select all

C:\Program Files\7-Zip\7z.exe" h -scrcsha256 "Test.7z" | findstr /c:"SHA256 for data"

In that case you should note that the "for /f" loop only creates one line that you skip, so it might help to not skip that line:

Code: Select all

for /f "tokens=* usebackq" %%a in (`^""C:\Program Files\7-Zip\7z.exe" h -scrcsha256 "Test.7z" ^| findstr /c:"SHA256 for data"^"`) do echo %%a
