[HELP] Batch File Creation
« on: May 29, 2013, 08:50:09 am »
Hello and Good Day,

I would like to create a batch file, wich I dont know how to make (n00b!). I am not much familiar on MSDOS Commands but on the contrary I only know a small portion of it.

The format would be this:

Legend: Program = prg, SourceFile = sf, Output = out

prog sf out

I would like to input a lot of source files "sf01.mp sf02.mp sf03.mp... and-so-on" that would retain their original filenames but with a "_dec" on the end of the filename. Thank You

Regards,
Nyxos

Normally you would write the for loop by hand on the command line to take care of the exact naming convention you want, as a throwaway. Well, you would if the shell were sane, which is pretty much exactly what the Windows/DOS shell is not. In a Unix-style shell this would easily be a one-liner. In bash, I would write:
Code: [Select]
for i in `seq -w 1 99`; do prog sf${i}.mp sf${i}_dec.mp
No such luck with the Windows shell; the required code is long and complicated enough you wouldn’t want to try doing this without putting in a file first (and I wouldn’t want to try wasting like 30 minutes writing the equivalent script such that it won’t break anything, being that I’m not sitting at a Windows box...). If it were very important that it run on an end user’s computer, that’d be another matter, but if it’s just for you I seriously urge installing something that’s going to make this go down better, such as MSYS (which comes with bash and would be a reasonably gentle introduction to Unix commands, a sort of gateway drug to being a full on command line warrior) or Windows PowerShell (which I personally know nothing about but everyone says it’s way better than the default so I’ll trust them on that one).

Are you running this in DOS, or in Windows?

Windows Vista and Windows 7 include a command called "FORFILES" which would be very useful in this case.
This signature is an illusion and is a trap devised by Satan. Go ahead dauntlessly! Make rapid progres!

I am running Windows 7 (not mine) atm. I would like to run it. As stated on my main post I don't really have much knowledge on MSDOS.

Thank you for the codes BRPXQZME, but I require the code on MSDOS (Windows Shell), I don't possess a PC that can run a Virtual Machine to run the code on a Unix system for now (PC is slow as heck). As for Cygwin and Mysis, I don't want to install such programs on this PC cause its not mine, though I have them on my Laptop but my LT has a busted Backlight which in turn I cannot use :). Anyways thank you for the replies, though I really require that program :)

Regards,
Nyxos

You can always learn.  ;D

FORFILES is ingeniously straightforward.  It looks like all you need is
Code: [Select]
FORFILES /c "cmd /c prog @file @fname_dec.@ext"
For every file in the current directory, this will run the command
Code: [Select]
prog [filename].[ext] [filename]_dec.[ext]
The alternative would be to throw something together with Excel (or some other spreadsheet) using its string-concatenation functions.  Ugly, but it works.

Is this the code?
Code: [Select]
FORFILES /c "cmd /c prog @file @fname_dec.@ext"
i would like to run the program through all the files with a extension .fv and then the output files would have a *_dec.fv added to their filenames as the output, sorry for being a n00b at this ;D.

EDIT: Solved!
Figured it out myself with your format @Jorpho-san, here's what I did
Code: [Select]
FORFILES /p *path/folder of the sourcefiles* /c "cmd /c
progam.exe @file @fname_dec.@ext"

I thank you for helping me a lot.  :)

Regards,
Nyxos

AHA! Never heard of that one. Yes, that is a much better command; it just got added around the time I quit heavy Windows usage. m(_ _)m

I am also surprised that a command such as that exist xD or is it just me not knowing better xDxD. Thank you also for your help

Apart that putting "multifile rename" in google would teach you everything this guys told you,
you would had found many window (free) tools to do this. Here some examples:

Personally, I use Bulk Rename Utility since I don't need to change mp3 tags.  The GUI is a bit overwhelming at first.

No, I didn't require any Batch Renaming Utility. I needed a Batch file to run my program through various files and output them as their generic filename with a *_dec added to it. Sorry for not making this clear.
