Code:

`get your data via these commands` > file.txt

You can do "> foo.txt" to redirect STDOUT output to a text file. ">" overwrites any file that's there, ">>" appends onto the end.

Pretty simply shell scripting.

hrm...

im having some troubles

#include <iostream>
#include <string>
using namespace std;

int main(){
string mystring = "Hello World";
mystring > helloworld.txt;

return 0;
}

and then it gives me this error:

exercise9.cc: In function `int main()':
exercise9.cc:7: `helloworld' undeclared (first use this function)
exercise9.cc:7: (Each undeclared identifier is reported only once for each
function it appears in.)

any suggestions?

thanks

You need to look at the fstream libraries. Specifically ofstream. Just create the file write out to it as you would cout and then close the file.

The example I gave was shell, NOT C. You use it in a BASH-type script or on the Command prompt.
