batch file to loop through every file in a folder

Question

i have created a script and wanna it to loop through all the file in a directory.. but i failed to do that.. i create another script to apply the script (change_content).. here the code,

cd \input

for %%f in (*.txt) do (

            echo "%%~nf"
            "D:\deployment code\change_content" .\"%%~nf".txt
    )

change_content.bat

call :yesterday today -1
for /f "delims=" %%a in (%1) do (
set "val=%%a"
if "!val:~12,10!"=="0001-01-01" (
>> D:\temp\%1_changed.txt echo !val:~0,12!%day%!val:~22!
) else (
>> D:\temp\%1_changed.txtecho %%a     
)
)

My problem is i cant let the script to read the input file if i put it as variable. I can only put the actual file which not helpful in automate the process? this is just part of the code where i point to the input and output direction.. just wondering what should i do at the for /f place..

Would be appreciate if anyone could help on this..thanks :)

install Cygwin. Use bash. You'll be happier...

I understand your problem as what you listed in bold text above. The following should work, going from memory, but I cannot test it now as I am without a Windows computer now ( and happy I don't have to have one with me ).

If you are instersted in the main program looping portion, try this:

setlocal eneabledelayedexpansion

REM:: take \input as param from command line
set top_folder=%~1
set change_content="D:\deployment code\change_content.bat"

for /f "eol=; tokens=1 delims=" %%t in ( 'dir /b !top_folder!\*.txt' ) do (
  REM:: the /b may or may not give yo the full path you need
  REM:: google this if I am wrong

  set file_name=%%~nt
  !change_content! !file_name!

)

If you are interested in the change_content portion, try this:

setlocal enabledelayedexpansion

REM:: change_content looping over file_name variable.
set file_name=%~1
for /f "eol=; tokens=1 delims=" %%f in ( 'type "!file_name!"' ) do (
  set line=%%f
  REM::  Do your thang in here with !line!.
)
