title: How to safely use http_proxy variable in linux
body: <p>I got complicated about <code>http_proxy</code> on our linux server.
  The thing is that we use to go through our proxy, which is preferenced on ldap,
  so I must use my machine's login and password in <code>http_proxy</code> to be able to download something from the ssh client. I can edit <code>bash_profile</code> with that, I can use alias for curl like <code>curlp</code> where I could set proxy login and proxy password.</p>
  
  <p>But my password is opened for all my colleagues anyways.</p>
