Help coding advanced batch file (DOS)

[ADLANCAS]

Hi,

I´ve put a thread in DVD Rebuilder area, but maybe here a better place to put, since this is basically a DOS command line thema. And there I had no help:(

I think about using rejig in a batch file (.bat).
All my encodes are made in this .bat, like this:

"C:\Arquivos de programas\Custom Technology\CCE SP Trial Version\cctspt.exe" -ecl "D:\cce.ecl" -batch

I have not so much knowledges in batch files, but the idea is:
-checks the size of all files *.m2v in drive D:\;
-compare the sum of them to 4000MB;
-resize if greater then x%, to fit 4000MB;

Could someone help to code this batch file ?
Thanks,

Alexandre

PS. Moderator, please fell free to move to another thread if it´s necessary and sorry if I made a mistake.

Não sei se isso é possível. Terceira parte é o mais difícil. O que é mau com DVDRebuilder?

(I don't know if that is possible. The third part is the most difficult. What is bad with DVDRebuilder?)

Which translates to?

mmm , look at this

SET SIZE1=0
SET SIZE=0
FOR %%i in ("DIR /B "D:\*.m2v") DO ECHO %%~zi >>D:\size.txt
FOR %%i in ("DIR /B "D:\*.m2v") DO ECHO d:\%%i + >>D:\list.txt
FOR /F "tokens=*" %%i in ('type "d:\list.txt"') DO SET LIST=%%i

FOR /F "tokens=*" %%i in ('type "d:\size.txt"') DO SET /A SIZE1=%%i+%SIZE1%

SET /A HIT=(%SIZE1%/4194304000)*100

IF %HIT% GEQ 101 SET /A HIT=%HIT%-100
IF %HIT% GEQ 1 FOR /F "tokens=*" %%i in ("rejig.exe -level %HIT% -o %LIST% -i d:\movie.mv2 -close -quiet -auto") DO CALL START /MIN /LOW /WAIT %%i


dunno if is correct i cannot test in this moment
but hope that helps !

Hi,

@Int 21h,
What´s wrong with DVD Rebuilder? I don´t know, because I´ve never used. Makes sense to use it for what I need ?

@Nic
Do you speak portuguese ?:D

@buzzqw
Thanks a lot. I´ll test, and try to understand it.
It´d help if you could explain the code a little bit:)

SET SIZE1=0 ->set variable size :D
SET SIZE=0 ->set variable size :D

FOR %%i in ("DIR /B "D:\*.m2v") DO ECHO %%~zi >>D:\size.txt --> create file named size.txt with only the size of each file, in byte

FOR %%i in ("DIR /B "D:\*.m2v") DO ECHO d:\%%i + >>D:\list.txt --> create a file named list.txt with only the names of all file m2v. The file is like "d:\1.m2v + d:\2.m2v + ..."

FOR /F "tokens=*" %%i in ('type "d:\list.txt"') DO SET LIST=%%i --> since rejig do not want a file list with all file to work, i must do something..., so i type list.txt into a variable named %LIST%

FOR /F "tokens=*" %%i in ('type "d:\size.txt"') DO SET /A SIZE1=%%i+%SIZE1% --> the wrong part (i think). Sum all values (typed into size.txt) in %SIZE1%

SET /A HIT=(%SIZE1%/4194304000)*100 --> get the % between sum_size and 4000mb*1024kb*1024byte

IF %HIT% GEQ 101 SET /A HIT=%HIT%-100 --> if % >= 101, decrease by 100. This is the reduction factor for Rejig

IF %HIT% GEQ 1 FOR /F "tokens=*" %%i in ("rejig.exe -level %HIT% -o %LIST% -i d:\movie.mv2 -close -quiet -auto") DO CALL START /MIN /LOW /WAIT %%i --> launch rejig, minimized, in low priority, and wait to launch other task

That script won't work, since dir/b will only show the file names, not the sizes.

The script below get's the sizes and filenames from a dir.
Attention! after delims there is a tab, followed by a space.
put your own stuff in the process subroutine to do something with the filenames and sizes in %3 and %2 resp.

@echo off
FOR /F "tokens=1-4 skip=7delims= " %%I in ('DIR /-C *.mv2') do call :process %%J %%K %%L

%%M
goto :EOF


:process
if /I "%1" == "File(s)" goto :eof
if /I "%1" == "Dir(s)" goto :eof
echo size of %3 = %2 bytes
goto :eof



that smily is a : followed by process. The forum turns that into :process

[buzzqw]

just a note

%%~zi is file size

@buzzqw
I put only first 3 lines to see the file size.txt but didn´t work:
SET SIZE1=0
SET SIZE=0
FOR %%i in ("DIR /B "D:\*.m2v") DO ECHO %%~zi >>D:\size.txt
pause

@Arachnotron
It works, but I´m totally limited to continue this code. I´ve put a pause to see what´s happen.
REM @echo off
FOR /F "tokens=1-4 skip=7delims= " %%I in ('DIR /-C D:\*.m2v') do call :process %%J %%K %%L

%%M

goto :EOF

:process
if /I "%1" == "File(s)" goto :eof
if /I "%1" == "Dir(s)" goto :eof
echo size of %3 = %2 bytes
pause

goto :eof

[buzzqw]

FOR %%i in (DIR /B D:\*.m2v) DO ECHO %%~zi >>D:\size.txt

I'm sure someone's happy that his ancient DOS *.bat skills are in demand.

[Arachnotron]

I'm sure someone's happy that his ancient DOS *.bat skills are in demand.Actually, this stuff only works with the extended support available in Windows NT and higher, it would never run under true DOS :)

@buzzqw
You are perfectly right, My bad :) ~z indeed expands a variable holding a filename to it's size.

Ack, sorry, I have seen so many threads with fragments of various languages I didn't think to read the rules and see that !English is not allowed.

Honestly, I was just goofing around trying to produce Portuguese, won't do it again.

[markrb]

I never saw having another language written here as any problem as long as a translation to English is provided in the same post. This way all parties know what you are talking about and can learn.

I may not be right here so don't shoot me.

@Arachnotron
Thanks for the links. I´ll check them.

@buzzqw
I saw 3 things:
- Sum doesn´t work (as you suppose);
- In the line SET /A HIT=(%SIZE1%/4194304000)*100 , it seems that variable HIT is a integer. It should be a real value;
- Line for rejig doesn´t work.I´m trying to find help for rejig command line. I´ve made a big searched, but until now I didn´t find out.

I´ll continue to test and learn. ;)
