To set a proxy for Ubuntu using the command line

To set a proxy for Ubuntu using the command line, you can use the following steps:

1. Open a terminal window.
2. Run the command to open .bashrc file.

nano ~/.bashrc

3. In the file that opens, add the following lines at the end of the file, writing or replacing PROXY_URL and PROXY_PORT with the appropriate values for your proxy server:

export http_proxy="http://PROXY_URL:PROXY_PORT"
export https_proxy="https://PROXY_URL:PROXY_PORT"

4. Press "CTRL + O" to save the changes and "CTRL + X" to exit the editor.
5. Run the command to apply the changes.

    source ~/.bashrc

6. This sets the proxy for the current user only. If you want to set the proxy for the entire system, you can add the same lines to the /etc/environment file instead of ~/.bashrc


Note that this is a general method for setting a proxy for Ubuntu, and the exact steps may vary depending on the version of Ubuntu or the proxy server software you are using.
