How to make unique output names using BAT?

Question

cmd/bat

Hello, there is a script:
chcp 1251
set CurPath=%cd%
cd C:\Program Files\Crypto Pro\CSP
call csptest -sfsign -sign -in %CurPath%\delo.pdf -out %CurPath%\delo.pdf.sig -my Primakov AA
cd %CurPath%
As you can see, the script for one file is specified explicitly. Please, tell me what should I use, so that the script would be executed for all pdf files in the folder and their names with the pdf.sig extension would be saved on the output?

Answer 1

Instead of a parameter in the batch file, write %1 %2
for /f "delims=" %%F in ('dir *.pdf /AD /TW /B') do call a.bat %%F
Place your script in the batch file and replace \ delo.pdf - %1 as parameter
for /f "delims=" %%F in ('dir *.pdf /AD /TW /B') - loop through parsing list of files.
