Having some issues calling awk from within Python. Normally, I'd do the following to call the command in awk from the command line.

1. Open up command line, in admin mode or not.
2. Change my directory to `awk.exe`, namely `cd R\GnuWin32\bin`
3. Call `awk -F "," "{ print > (\"split-\" $10 \".csv\") }" large.csv`

My command is used to split up the `large.csv` file based on the 10th column into a number of files named `split-[COL VAL HERE].csv`. I have no issues running this command. I tried to run the same code in Python using `subprocess.call()` but I'm having some issues. I run the following code:

```
def split_ByInputColumn():
     subprocess.call(['C:/R/GnuWin32/bin/awk.exe', '-F', '\",\"', 
              '\"{ print > (\\"split-\\" $10 \\".csv\\") }\"', 'large.csv'],
                  cwd = 'C:/R/GnuWin32/bin/')

```

and clearly, something is running when I execute the function (CPU usage, etc) but when I go to check `C:/R/GnuWin32/bin/` there are no split files in the directory. Any idea on what's going wrong?
