Automate Proxy Server Settings In Linux

$ export {http,https,ftp}_proxy="http://PROXY_SERVER:PORT"
$ unset {http,https,ftp}_proxy

If you use a proxy server often, you can create Bash functions as follows (add to your ~/.bashrc file):

# Set Proxy
function setproxy() {
export {http,https,ftp}_proxy="http://PROXY_SERVER:PORT"
}

# Unset Proxy
function unsetproxy() {
unset {http,https,ftp}_proxy
}
Reload your ~/.bashrc file.

$ source ~/.bashrc
