Thread: C program to record a CMD commands output and put it in a file

Hi guys, maybe I am overworking myself, I think its something simple. I need to record the output of a CMD command to a file.

Code:

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


// Function prototypes
void RecordOutput();


int main()
{
    char educode[100];
    char CommandOutput[128];
    printf("Welcome to the network software check software!\n");
    printf("\nPlease type your license code!");
    printf("\nEducator Code: ");
    gets(educode);


    if(strcmp(educode, "5678") == 0 )
    {
        system("ping abv.bg -t");
        RecordOutput();
    }
    else
    {
        printf("\nSorry, thats not a valid Educator Code.");
    }


    return 0;
}


void RecordOutput()
{
    printf("Debug: Recording started\n");
         char CommandOutput[128];
         char *f1 = "C://Users//internalhdd//Desktop//RecordingOutput.txt";
         FILE *inFile;                                             //Declare inFile


         char Byte;
         /*int  n;*/


                                    /******USER INPUT BLOCK*******/
        gets(CommandOutput);
         /*int i=0;*/
                                    /******FILE OPEN BLOCK********/
         inFile = fopen(f1,"w");


                                    /*****MAIN PROGRAM BLOCK******/
         if(inFile == NULL)                     /* check if the input file is empty */
         {
            printf("Error: Can't Open inFile\n");
         }

         else
         {
                  printf("File Opened, Recording\n");
                                                /* recording cycle */
                  while(1)
                  {
                           printf(".");                /* loading symbol */


                                                     /* if the current byte is not the end of the command's output */
                           if(Byte!=EOF)
                           {                          /* Byte = function get char from "inFile" */
                                    Byte = fgetc (CommandOutput);
                           //         printf("%d",Byte); /* the new byte from the command output */
                                                    /* we put the new byte in the file */
                                    fputc(Byte, inFile);


                           }
                                                    /* if the command is over */
                           else
                           {
                                    printf("End of the recording\n");
                           }
                    return 1;
                  }
         }
}
