Configuring proxy client on terminal without leaving password on screen or in bash_history

Prompts the user for username and password, that are then exported to http_proxy for use by wget, yum etc

Default user, webproxy and port are used.

Using this script prevent the cleartext user and pass being in your bash_history and on-screen

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
export http_proxy=<user>:<pass>@<server>:<port> ftp_proxy=<user>:<pass>@<server>:<port>

Know a better way?

If you can do better, submit your command here.

What others think

But doesn't that leave your password inside the environment variables? Anyone typing env can get it, then.

From my testing the environment variable is only set for the user for that session.

Please correct me if you think I'm mistaken as my credentials might be exposed!
