output redirction don't work.

[ascitegong]

Thanks for developing this tool.
It works in Powershell cmd line, but don‘t work if output is redirected.
cmd such as this don't work:
sshpass.exe -p xxxxxx ssh -p 22 -l username 192.168.1.10 ls / > output.txt
An empty output.txt file is generated after run.
