How would netsh help?
Netsh is also localized and changing the codepage does possibly not
change the output language. Changing the language would also require
'.../en-US/netsh.exe.mui' file which is not necessarily installed.
If netsh is run interactively, it prints a deprecation warning for
'interface' and other commands and recommends usage of powershell.
This works but is slow and might violate local security policy:
powersh()
{
local x
# May require '-ExecutionPolicy ...'
if ! x=$(powershell -NoProfile -Command "$@" 2>/dev/null); then
echo "powershell: failed" >&2
return 1
fi
echo "$x" | tr -d '\r'
}
search=$(powersh \
'Get-DnsClientGlobalSetting `
| ForEach-Object SuffixSearchList')
nameservers=$(powersh \
'Get-DnsClientServerAddress `
| ForEach-Object ServerAddresses `
| select -Unique')
# Alternatively
nameservers=$(powersh \
'Get-NetIPConfiguration `
| ForEach-Object DNSServer `
| ForEach-Object ServerAddresses `
| select -Unique')
...
