Why is the netstat utility help not being redirected to a file?

Question

cmd/bat

dir /? > temp.txt
prints help on the dir command to a file without problems, but
netstat /? > temp.txt
not. The output is made to the console, and the temp.txt file is created, but empty.

Answer 1

most likely the output goes to stderr. The construct 2>&1will redirect stderr to stdout
netstat /? 1>temp.txt 2>&1
