HI,

I am using this for coping the data from one file to other file with file name between each file.

Code:
while(!feof(stdin)) {
        while ((fgets(strLine,sizeof strLine, stdin) != NULL) && (!feof(stdin))) {

        if ((strcmp(strLine, "File") != 0) && (strcmp(strLine, "Total=") != 0)) {


                                fprintf (fp1, strLine);
        }
        }
        fclose(fp1);
        fp1 = fopen("FinalScan.temp", "r");

        while ((fgets(strLine,sizeof strLine, fp1) != NULL) && (!feof(fp1))) {

        if ((strcmp(strLine, "File") != 0)) {

                                strcpy(strLine2,strLine);
                                fprintf (fp, strLine);
        }
        }

Regards,
Jhon.

Any particular reason you want to do this in C? It'd be a snap in shell...

Some of that's a bit redundant.
Code:
char buf[1024], header[1024];

header[0]='\0';

while(fgets(buf, sizeof(buf), stdin))
{
        if(strncmp(buf, "----", 4) == 0)
        {
                strcpy(header, buf);
                continue;
        }

        fputs(header, stdout);
        fputs(buf, stdout);
}

Should match the ---- lines, and print them first for every line that isn't one.

How we'll redirect this to a file???
# 6  
Old 02-22-2012
Code:
./program < input > output

Or, if that's not what you want, please explain what you do. Your original explanation showed it all being read from one big file and all being written to one big file.
