Is there a scheduled program that replaces the host file or quickly switches (to itself to block the Internet from prostratination)?

Question

Time Management

Is there a program. So that you can quickly change the host file or on a schedule .. To work, and not hang out on youtube and social networks? Windows.

Answer 1

The cp command (linux) or the copy command (windows) can easily "switch" the host file for you.
The built-in cron (linux) or scheduling service (windows) can easily schedule this automatically.
What exactly is your problem?

Answer 2

There are many such programs. Including browser extensions.
If you need to disconnect from the Internet - do it programmatically or pull out the cord.
If you block certain sites - there are many programs, as I already wrote.
You drive in the addresses of the sites, put a password of 20 letters, so that it would be too lazy to drive in.
But! All this does not help. You switch either to other sites, or you suffer from other garbage.
Procrastination is treated only with a lot of work, there are no other cures.
