Dumpcap -D outputting results to text file

["Keith French" <keithfrench () btconnect com>]

I need to get the list of available interfaces from Dumpcap via a batch file. I am using Wireshark V1.6.1 on Windows 7. 
This always used to work, but now doesn’t for some reason. The contents of the batch file are:-

"C:\Program Files\Wireshark\dumpcap.exe" -D > "C:\Program Files\Wireshark\output.txt"

There are no results in the text file.

If I run it from a cmd window using the syntax:-

dumpcap -D > "C:\Program Files\Wireshark\output.txt"

I get the output from dumpcap –D in the cmd window, but nothing in the text file.

I also tried from a cmd window:-

dir > "C:\Program Files\Wireshark\output.txt"

In this case there was no output in the cmd window, but the normal dir response was in the text file as you would 
expect.

Any ideas?
