help with a .bat file

[xfusion]

ok so i need to write a .bat file that will when placed in a folder, enter every folder in that folder, run this

ren *_std *_std.mpg

then also, if any of the file names start with 2,3,4,5,6,7,8,9 it will add a 0 before each of them, IE

2-filename.mpg (they are all mpg's)  -> rename to -> 02-filename.mpg

was wondering if anyone could help me create this, any help is appreciated, thanks

Hi there.  What have you got so far?  Any code? More detailed algorithm?

I suggest:
-The dir command
-The for command <--what out when you're using this
-You might also use the for command to add the 0, if the number is always before a particular character (eg. '-').

We will help you further if you show that you tried hard .

Hope this helps

Code: [Select]

Set objFS=CreateObject("Scripting.FileSystemObject")
strFolder="C:\test"
Set objFolder = objFS.GetFolder(strFolder)
For Each strFile In objFolder.Files
strFileName = strFile.Name
If objFs.GetExtensionName(strFileName) = "mpg" Then
c=Mid(strFileName,1,1)
If c >=2 Or c<=9 Then
strNewFileName = "0"&strFileName
WScript.Echo strNewFileName
strFile.Name = strNewFileName
End If
End If
Next
save as change.vbs and one command line

Code: [Select]

c:\test> cscript //nologo change.vbs

all i have so far is

ren *_std *_std.mpg

i'm use to c++ so i'm not quite sure on -how- to completely accomplish, mostly on the searching through files aspect, i know i'll need a setup like
go into directory
ren *_std *_std.mpg
if(starts with 2- add 0 to beginning of filename)
if(starts with 3- add 0 to beginning of filename)
ect ect
go to next directory, repeat until it has gone through each directory (note that there is never definite amount of directory's in the folder, vary's between 15-30 most of the time)

i'm just not sure on how exactly to code it

C:\batch>type  fus2.bat
REM  Goto root directory and search all subfolders with
REM  dir /s en *_std*

REM  Example:

Code: [Select]

@echo off

E:

dir /s toy*.txt  >   e:\std.txt

cd e:\

copy  e:\std.txt  c:\batch\std.txt


for /f "tokens=5 delims= "  %%a in (c:\batch\std.txt) do (echo %%a )


for /f "tokens=5 delims= " %%a in (c:\batch\std.txt) do (
echo %%a.mpg >> c:\batch\ans.txt
)

C:
echo Type  c:\batch\ans.txt
echo.
type  c:\batch\ans.txt

del  c:\batch\ans.txt

C:\batch> fus2.bat

C:\batch>REM  Goto root directory and search all subfolders with

so how does that answer the question, bill, Joan, Bill, and Mike? (Which one am I speaking to today?)

[xfusion]

that just adds .mpg to all the files in the folder, i already have that working perfectly with

ren *_std *_std.mpg

(this only renames the files i need to rename because along with the mpg's in the folder, there's also .idx files that should not be renamed, along with a xml document that should not be renamed)
its just that currently i have to copy my .bat into every sub folder and run it

xfusion, billrich is a person with mental health issues who has been banned under several different names, but he keeps coming back, and the mods won't do anything about it. Please just ignore him.

i was kinda confused on why he sent me that last night as a message...

[billrich]

Please, xfusion,  post the solution that worked for you.  The solution will help many people.

He has sent me a message or two. A sad case.

[billrich]

"I was kinda confused on why he sent me that last night as a message."

Negative messages should be sent as a message and not posted.

Indeed, negative messages should not be used by anyone.

Good luck with your project. I hope your rename process works.

Especially that one you sent me about my mother. That shameful message.

getting back on topic...

[Two-eyes]

I know I will be killed about this:  Salmon Trout and billrich have a...."interesting" relationship.  Don't think they did this for the first time....just a heads up.

getting back on topic...

Yes, let's.

The "dir /s" command will list every file in the directory the command is run in and in every sub-directory, sub-sub-directory etc (I think that's why it's an "s"), as you want it.
The "dir /b /s" will only list the names of the files. (see the difference the "b" switch does by trying the two different commands [without the "s" switch]).

Redirecting that output to a txt file works like this: "dir /b /s > myText.txt".

Then check out the for command.  It is too long and complicated to explain quickly, but you can extract the info you need for now.  What I think you need is "for /f %%x in (myText.txt) do ( ren %x% %x%.mpg)".  The renaming part might not work.  This might be because of "delayed expansion"...another long-ish topic that you can find a lot of information about .

As for the 2-9 thing, if the number will always be before a hyphen('-') you can use the for command with the options "tokens=1 delims=-", then check (using an if statement) if it's between 2 and 9, and if so, add the '0'.

There is a lot of documentation out there that you can use to bring together this project of yours, go look for it .

Hope this helps

PS. do you strictly need a batch file solution?  ghostdog is an experiences vbs programmer and most probably...(99.99% )... his script is correct....
