Steps to use this
-----------------
1) compile randstr.c ==> randstr.exe using DJGPP's gcc
  - gcc randstr.c -std=c99 -o randstr.exe
2) copy both randstr.exe and sgit.bat to your local bin directory
3) Verify you have curl and tar installed
4) Now you can pull any github project onto your freedos machine :) Enjoy

randstr.c

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

char rand_char(){

        char printable[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890";
        int size = (int)sizeof(printable);
        int rindex=rand() % size;
        return printable[rindex];

}

int main(int argc, char **argv){

        int ret_code=0;
        int length;
        srand(time(NULL));
        if(argc!=2){

                ret_code=1;
                printf("ERROR: NEEDS EXACTLY ONE ARGUMENT");

        } else {

                length=atoi(argv[1]);
                for(int index=0;index<length;index++){

                        printf("%c",rand_char());

                }

        };
        return ret_code;

}
