How do I create my own custom hosts file?

For some specific reasons I don't want to edit the /etc/hosts file and that is why I needed to create my own hosts file in suppose ~/hosts and use it for all IP to HOSTNAME mapping along with the system's /etc/hosts file. How will I be able to do this?

Solution 1:

Using the environment variable HOSTALIASES:

Define the environment variable HOSTALIASES
```
export HOSTALIASES=~/.hosts
```

Create your private hosts file and add a test entry

echo 'myprivategoogle www.google.com' > ~/.hosts

Start a test

curl myprivategoogle

without the entry in ~/.hosts you would get

curl: (6) Could not resolve host: myprivategoogle

with the entry you have

<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>302 Moved</TITLE></HEAD><BODY>
<H1>302 Moved</H1>
The document has moved
<A HREF="http://www.google.com/">here</A>.
</BODY></HTML>
