How to connect to the specified network through a bat file?

Question

Computer networks

In a third-party program (written in ancient Roman), I get a list of available networks, through a third-party bat file.

What I need is for me to select the network to which I want to connect in my program and bat read it, for example, from the file connectnow.txt
Text: Ethernet
Then I connected to it,
and the same thing when disconnecting from the network.
disconnectnow.txt
Text:Ethernet

Help me out

Answer 1

Using the contents of a file in a command:

set /p ARGS= <connectnow.txt && netsh interface set interface "%ARGS%" enable
set /p ARGS= <disconnectnow.txt && netsh interface set interface "%ARGS%" disable

Option 1 (requires admin rights):

подключиться к сети 
netsh interface set interface "Ethernet" enable
отключиться от сети
netsh interface set interface "Ethernet" disable

Option 2 (requires admin rights):

подключиться к сети
netsh interface set interface name="Ethernet" admin=ENABLED
отключиться от сети
netsh interface set interface name="Ethernet" admin=DISABLED

Option 3:

подключиться к сети
Enable-NetAdapter -InterfaceAlias "Ethernet"
отключиться от сети
Disable-NetAdapter -InterfaceAlias "Ethernet"
