Thread: open several files and execute?

I have an external .exe that will process a single file at a time. The problem is i have several hundreds of files to process, so i wanted to implement some code that allows me to loop an instruction for every file in a directory (all are named *.xyz).

Any sugestions please?
Thanks

It`s a windows machine

replace echo with your prog name, put the whole thing in a file with a .bat extension and let rip

Found another problem...

Code:

FOR %%c in (C:\*.pc) DO normfet.exe %%c %%c.txt -nml

Won`t write anything to %%c.txt(i need the prefix of the original file on the output file). It works if the syntaxe is only "program infile outfile", but the "-nml" wont allow the write of the outfile, although the program runs fine.

Any ideas?

Let's the part of your code, where you deal with the arguments

QuantumPete

the program is not mine (normfet.exe), i am using the executable only.
"-nml" is one instruction to the program. I run a similar batch script with other programs, it only fails with this one.

Have you tried putting the -nml at the beginning? Most programs expect their arguments first and then any other files

QuantumPete

Yes i tried changing the order but it errors out. What i think is strange is the fact that i can see that the "normfet.exe" is working but still nothing is written.

Code:

Usage: Normfet.exe <infile> <outfile_prefix> [-nml | -bbr ...]

I wrote the following:

Code:

#include <stdio.h> 
#include <string.h> 

int main(int argc, char *argv[])
{
  char child1[] = "normfet.exe";
  char child2[BUFSIZ];
  char child3[BUFSIZ];
  
  // nome saida
  strcpy (child3, argv[1]);
  strcat (child3, "nm");

  strcpy (child2, child1);
  strcat (child2, " ");
  strcat (child2, argv[1]);
  strcat (child2, " ");
  strcat (child2, child3);
  strcat (child2, " -nml -ftr");
  
  printf ("Executing %s\n", child2);
  system (child2);
  
  return 0;
}

and then used the batch script with

Code:

FOR %%c in (C:\3d\*.xyz) DO tnormefet.exe %%c

but it errors out just before finishing. I guess there is nothing else to do, normfet.exe killed my plans.
