Read input file, create seperate files based on table

#1 Post by darioit » 09 Aug 2010 06:17

Hello
I read this article "batch file to read imput file, create seperate files " and I have a issue very similar

This is my sequential input file:
AA00codeotherdata
AAotherdata
......
AA99codeotherdata

this is my table:
code;newcode
.....;.........

I'd like to create new file called newfile.newcode.txt splitting with beginning AAcode from table and end with AA99code

this is example of file name
AA001234other
AAsomedata
AA991234other
AA005678other
AAsomedata
AA995678other

table:
1234;rome
5678;milan

new file :
fix.rome.txt
fix.milan.txt

Thanks

Are all files you want to rename in the same folder?
Are always the first 4 characters used for the new files too?
Is the length of (old) code always 4 characters?
What file extensions do the old file names have?
Are there special characters (like "&") used in file names?

Regards
aGerman

Are all files you want to rename in the same folder? yes
Are always the first 4 characters used for the new files too? variable
Is the length of (old) code always 4 characters? yes it depends on table, but yes 4
What file extensions do the old file names have? g00v00xxx where xxx is sequential but one is processed at time
Are there special characters (like "&") used in file names? no not used only dot separe file name

Tomorrow I give you a more detailed sample

Kind Regards
Dario

You could try this:
The batch file, Table1.txt and Table2.txt are in the same folder (but not together with the other files).

Code: Select all

 
@echo off &setlocal
pushd "C:\your\folder\with\files"

for /f "delims=" %%a in ('dir /a-d /b') do (
  set "name=%%a"
  call :procName
)

popd
pause
goto :eof


:procName
set "newCode1="
set "newCode2="

set "prodCode=%name:~0,2%"
set "num=%name:~2,2%"
set "oldCode=%name:~4,4%"

for /f "usebackq tokens=1* delims=;" %%a in ("%~dp0Table1.txt") do (
  if "%oldCode%"=="%%a" set "newCode1=%%b"
)

for /f "usebackq tokens=1* delims=;" %%a in ("%~dp0Table2.txt") do (
  if "%prodCode%"=="%%a" set "newCode2=%%b"
)

ECHO ren "%name%" "%prodCode%%num%.%newCode1%.%newCode2%.txt"
goto :eof


If you think it would work, remove the ECHO command.

Hello AGerman Thanks a lot it's almous perfect!
I make some changes and I have one two more question

The first is when I write the data
ECHO %name% >> "ADDRESS.%newCode1%.%newCode2%"
it's add a blank space at the end of line
The second question in when the batch read the code into the table to find the code I think there's no reason to read the table to the end, so the code must be fast

Here the code modified

Code: Select all

@echo off &setlocal
pushd "C:\your\folder\with\files"

set "newCode1="
set "newCode2="

for /f "delims=" %%a in (fileinput.txt) do (
  set "name=%%a"
  call :procName
)

popd
goto :eof

:procName

set "prodCode=%name:~0,2%"
set "num=%name:~2,2%"
set "oldCode=%name:~4,4%"

for /f "usebackq tokens=1,2 delims=;" %%a in ("%~dp0Table1.txt") do (
  if "%oldCode%"=="%%a" set "newCode1=%%b"
)

for /f "usebackq tokens=1,2 delims=;" %%a in ("%~dp0Table2.txt") do (
  if "%prodCode%"=="%%a" set "newCode2=%%b"
)

ECHO %name% >> "ADDRESS.%newCode1%.%newCode2%"

goto :eof

It's because of the space behind %name%
You can use

Code: Select all

ECHO %name%>> "ADDRESS.%newCode1%.%newCode2%"
or
>> "ADDRESS.%newCode1%.%newCode2%" ECHO %name%

You can break a for loop with a goto :label

Code: Select all

for /f "usebackq tokens=1,2 delims=;" %%a in ("%~dp0Table1.txt") do (
  if "%oldCode%"=="%%a" (
    set "newCode1=%%b"
    goto :break_loop
  )
)
:break_loop

ok thanks for your suggestion

I have simplify all operation and now is very fast, what do you think is correct writing code in this way?

@echo off &setlocal
pushd "E:\bat\Temp"

for /f "delims=" %%a in (fileinput.txt) do set "name=%%a"&call :procName

popd
goto :eof

:procName
if "%name:~2,2%"=="00" (
for /f "usebackq tokens=1,2 delims=;" %%a in ("%~dp0Table2.txt") do if "%name:~4,4%"=="%%a" set "newCode1=%%b"
for /f "usebackq tokens=1,2 delims=;" %%a in ("%~dp0Table1.txt") do if "%name:~0,2%"=="%%a" set "newCode2=%%b"
)

>> "ADDRESS.%newCode1%.%newCode2%" ECHO %name%
goto :eof

Think you could make it like jeb suggested.

Code: Select all

@echo off &setlocal
pushd "E:\bat\Temp"

for /f "delims=" %%a in (fileinput.txt) do set "name=%%a"&call :procName

popd
goto :eof

:procName
if "%name:~2,2%"=="00" (
  for /f "usebackq tokens=1,2 delims=;" %%a in ("%~dp0Table2.txt") do if "%name:~4,4%"=="%%a" (
    set "newCode1=%%b"
    for /f "usebackq tokens=1,2 delims=;" %%c in ("%~dp0Table1.txt") do if "%name:~0,2%"=="%%c" (
      set "newCode2=%%d"
      goto break_loop
    )
  )
)

:break_loop
>> "ADDRESS.%newCode1%.%newCode2%" ECHO %name%
goto :eof


[Edit: Think you have to use different names for the dynamic variables in the 2nd FOR loop in this case /]

Thanks you very mutch now it works very fast, but I have one more question, in a row I have

AA001234 data data & data data

and when I write %name% the simbol "&" is view like a separator and don't write the full row, why?
