Run program in subfolders - windows

Question

I'm trying to write a Windows batch script to run 2 programs through a bunch of folders. I'm not an expert at shell scripting but I try my best.
Here's what I'm trying to run through each folder...
The input for program1 is a .extension1 file which then produces a .extension2 file which then is run through program2 to generate what I need.
Before I run the script I cd into the folder. The programs are copied to the folder because they only work in the current working directory.
copy C:\program1 .
copy C:\program2 .
for %i in (*.extension1) do program1 "%i"
for %i in (*.extension2) do program2 "%i"
The data folder shown above contains hundreds of folders that I need to run the program in. I'd like to be able to do this in one big batch script.

Answer 1

#ECHO OFF
SETLOCAL
SET "sourcedir=U:\sourcedir\one"
PUSHD "%sourcedir%"
FOR /r %%a IN (*.ext1) DO (
PUSHD "%%~dpa"
ECHO(c:\program1 "%%~nxa"
popd
)
popd
GOTO :EOF
You would need to change the setting of sourcedir to suit your circumstances.
In all probability, this is all you would need - or at least, this is a framework.
Note that the routine will simply ECHO the required commands. This allows a harmless test (on a representative sub-tree) to ensure that the process should work on the entire tree.
Changing ECHO(c:\program1 to c:\program1 should execute the first program on each .ext1 file in the sub-tree. It would be unusual for a program to check that the file exists within the same directory as the executable - if it won't take a path, then "the current directory" would be assumed.
You don't say whether the program program1 produces a file called whatever.ext2 from whatever.ext1 or whether it produces somethingradicallydifferent.ext2. In all probability, the same name would be used.
If that is the case, then to run the second program, simply add after
ECHO(c:\program1 "%%~nxa"
ECHO(c:\program2 "%%~na.ext2"
Otherwise, simply repeat the entire block, changing ext1 to ext2
(I'll assume you can figure out that I've abbreviated the extensions)
If, on the off-chance the program(s) need to be in the same directory, then replace
ECHO(c:\program1 "%%~nxa"
with
echo n|C:\program1 . >nul 2>nul
ECHO(program1 "%%~nxa"
(and ditto for program 2, obviously). Here the n is echoed into the copy, so that the copy will only take place once. This could be improved but is probably only a theoretical requirement anyway since it's 99.9999% likely that executing c:\program? will work quite happily.
