Set up HTTP PROXY via command line in Linux/FreeBSD
Setting HTTP PROXY for command line tools such as wget/fetch/pkg_add/yum/apt-get on Linux and Freebsd.

 



Wget/apt-get/fetch/yum/pkg_add -rv and the rest of command line tools in Linux and FreeBSD that use HTTP protocol will not use the proxy settings from your Firefox/Konqueror/Opera browsers. Instead, an environment variable "HTTP_PROXY" must be set and exported.

 

Assuming that your HTTP Proxy IP address is 192.168.0.1 port 3128 (standard proxy port), you must use following command (as the user you wish you have this setting for):

# export HTTP_PROXY='http://192.168.0.1:3128'

Setting up HTTP Proxy with authentication for command line tools in FreeBSD and Linux

export HTTP_PROXY='http://username:password@192.168.0.1:3128'

In order to make this proxy permanent, add the line to your ~/.profile or /etc/profile or ~/(bash|ksh|sh)rc file.

The export command is obvious: it tells the shell that all programs started from this point on, to use this variable.

To unset this, use:

# export HTTP_PROXY=''

Use unset, not export by Noid at November 08th, 2011 - 08:10
The proper way of unsetting an environment variable is NOT setting it to the empty string. You should unset it:

unset HTTP_PROXY

http_proxy by Andrei at May 04th, 2010 - 10:21
seems that some shells require http_proxy(lowercase), not HTTP_PROXY (upper case)
