output 的源文件名

Question

I am trying to create a batch file using PDFtk to burst combine file in a certain directory to the output folder using the source file name (which can vary) as the input file name. for example

source directory:- D:\Temp\IN destination directory:- D:\Temp\OUT File name:- abcdefgh.pdf (which can vary) desired output file name:- abcdefgh-001.pdf, abcdefgh-002.pdf and so on

My batch file will reside in D:\Script The PDFtk.exe is in D:\PDFtk Server\bin

I tried for 1 whole day I can't get the input filename for the output. Can anyone help

My existing program:-

CD D:\Temp\IN

for /f "tokens=*" %%A in ('dir /b D:\Temp\IN\*.pdf') do (

set prefix=%%~ni )

set outname=%prefix%-%%03d-00.pdf 

path D:\PDFtk Server\bin

pdftk.exe D:\Temp\IN\%prefix% burst output D:\Temp\OUT\%outname%

exit

Answer 1

There are multiple errors in your approach the first one is that in a case like this you need local delayed expansion. For an initial % later use it as ! .

CD D:\Temp\IN

This is ok but would be better if it allowed for /Drive shifting to "quoted drive folder" (beware input folder must NOT in this case be same as output folder with this approach, it is best if output is a sibling as you have done or use a common parent is better.)

CD /D "D:\Temp\IN"

for /f "tokens=*" %%A in ('dir /b D:\Temp\IN\*.pdf') do (

set prefix=%%~ni )

You have mixed up %%A and %%i they should be the same, tokens is not needed in this case but usebackq is for odd filenames and add quotes, don't need current directory, and ) is way too early.

setlocal enabledelayedexpansion  
for /f "usebackq delims=="  %%A in (`dir /b *.pdf`) do (
set "prefix=%%~nA"

next part

set outname=%prefix%-%%03d-00.pdf  

again best quoted and needs using expansion
set "outname=.prefix!-%%03d-00.pdf"

path D:\PDFtk Server\bin

pdftk.exe D:\Temp\IN\%prefix% burst output D:\Temp\OUT\%outname%

better if combined and quoted you don't need to use Current Directory

"D:\PDFtk Server\bin\pdftk.exe" ".prefix:.pdf" burst output "D:\Temp\OUT\!outname!"

the terminal bracket goes here
)

exit

is superfluous

so all in all

CD /D "D:\Temp\IN"
setlocal enabledelayedexpansion
for /f "usebackq delims==" %%A in (`dir /b *.pdf`) do (
set "prefix=%%~nA"
set "outname=!prefix!-%%03d-00.pdf" 
"D:\PDFtk Server\bin\pdftk.exe" "!prefix!.pdf" burst output "D:\Temp\OUT\!outname!"
)

The whole command could be simplified to ONE line however to show where cuts can be made
try this

CD /D "D:\Temp"
for /f "usebackq delims==" %%A in (`dir /b IN\*.pdf`) do (
"D:\PDFtk Server\bin\pdftk.exe" "IN\%%~A" burst output "OUT\%%~nA-%%03d-00.pdf"
)

the need for usebackq delims== is because of later problems with characters such as filename (1).pdf

so we cannot shorten much more than

CD /D "D:\Temp" & for /f "usebackq delims==" %%A in (`dir /b IN\*.pdf`) do ("D:\PDFtk Server\bin\pdftk.exe" "IN\%%~A" burst output "OUT\%%~nA-%%03d-00.pdf")
