To use the "wget" command with a Squid proxy server, you need to set the "http_proxy" environment variable to the URL of the proxy server. "wget" is a command-line utility that allows you to download files from the web, and the "http_proxy" environment variable specifies the URL of the HTTP proxy server to use when downloading files.
To use "wget" with a Squid proxy server, follow these steps:
export http_proxy=http://proxy_server:port
Replace "proxy_server" with the hostname or IP address of the proxy server, and "port" with the port number of the proxy server.
wget http://url
Replace "url" with the URL of the file you want to download.
With these steps, you should be able to use "wget" with a Squid proxy server by setting the "http_proxy" environment variable. Consult the documentation of "wget" and Squid for more information on how to use these utilities.
