I need to split a file if it is over 2GB in size (or any size), preferably split on the lines. I have figured out how to get the file size using awk, and I can split the file based on the number of lines (which I got with wc -l) but I can't figure out how to connect them together in the script.

randbuffer
FBB::RandBuffer(3bobcat) random number streambuf FBB::RandBuffer(3bobcat)NAME
FBB::RandBuffer - std::streambuf generating random numbers
SYNOPSIS
#include <bobcat/randbuffer>
Linking option: -lbobcat
DESCRIPTION
FBB:RandBuffer objects may be used as a std::streambuf of std::istream objects to allow the extraction of random numbers from the stream.
NAMESPACE
FBB
All constructors, members, operators and manipulators, mentioned in this man-page, are defined in the namespace FBB.
INHERITS FROM
std::streambuf
CONSTRUCTOR
o Randbuffer(int min, int max, size_t seed = 1):
This Randbuffer() constructor initializes the random generator. The seed is used to initialze the random number generator.Random
values between min and max (inclusive) are returned.
VIRTUAL MEMBERS
o int underflow():
This function is called by std::istream objects using Randbuffer. It produces the next available random number, separating the ran-
dom numbers by one blanks space. Random values between min and max (inclusive) are returned (see the description of the construc-
tor).
INHERITED MEMBERS
Since the class uses public derivation from std::streambuf, all members of this class can be used.
EXAMPLE
#include <iostream>
#include <istream>
#include <bobcat/randbuffer>
#include <bobcat/a2x>
using namespace std;
using namespace FBB;
int main(int argc, char **argv)
{
if (argc == 1)
{
cout << "expect: nruns min max seed
";
return 1;
}
Randbuffer rb(A2x(argv[2]), A2x(argv[3]), A2x(argv[4]).to<size_t>());
istream istr(&rb);
for (int idx = A2x(argv[1]); idx--; )
{
int c;
if (!(istr >> c))
{
cout << "extraction failed
";
break;
}
cout << "next: " << c << endl;
}
int count = 0;
while (istr.unget())
count++;
cout << "number of successful unget()-calls: " << count << endl;
istr.clear();
istr >> count;
cout << "and read: " << count << endl;
return 0;
}
