Can you show me the command line to turn off proxy when I am using the command line terminal in Ubuntu?

As the other answer says there are some programs that don't look at the system at all you may have to set them up individually. For instance wget has a number of proxy options, that can be used to ignore or adapt the environmental proxy config during execution. Here are a number of areas in which the systems proxys can be set up.
Some Linux systems use /etc/environment
$ cat /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
http_proxy="http://192.168.1.250:8080/"
ftp_proxy="ftp://192.168.1.250:8080/"
https_proxy="https://192.168.1.250:8080/"
There is no uniform single set up other use env
$ env | grep -i proxy
NO_PROXY=localhost,127.0.0.0/8,127.0.1.1
http_proxy=http://192.168.1.250:8080/
FTP_PROXY=ftp://192.168.1.250:8080/
ftp_proxy=ftp://192.168.1.250:8080/
all_proxy=socks://192.168.1.250:8080/
ALL_PROXY=socks://192.168.1.250:8080/
HTTPS_PROXY=https://192.168.1.250:8080/
https_proxy=https://192.168.1.250:8080/
no_proxy=localhost,127.0.0.0/8,127.0.1.1
HTTP_PROXY=http://192.168.1.250:8080/
I would check out the ~/.bashrc to have setting applied automatically on system start up.
$ man env
$ man set
$ # The file section near the end of the bash manual.
$ man bash
FILES
/bin/bash
The bash executable
/etc/profile

Assuming you're talking about typical command-line software and an HTTP proxy:
Most command-line tools pick this up from the environment variable HTTP_PROXY
, so prior to running a command:
unset HTTP_PROXY
There can be some variation between software/platforms, and you might need to unset http_proxy
also.
Note that many programs store this information in their own config files, and are likely to ignore the environment, so you would have to address those on a case-by-case basis.

You can set or unset all variables at once in bash:
$ export {http,https,ftp}_proxy="http://proxy-server:port"
$ unset {http,https,ftp}_proxy
$ export {HTTP,HTTPS,FTP}_PROXY="http://proxy-server:port"
$ unset {HTTP,HTTPS,FTP}_PROXY
You can also add a shortcut to you ~/.bashrc
:
# Set Proxy
function setproxy() {
export {http,https,ftp}_proxy="http://proxy-server:port"
export {HTTP,HTTPS,FTP}_PROXY="http://proxy-server:port"
}
# Unset Proxy
function unsetproxy() {
unset {http,https,ftp}_proxy
unset {HTTP,HTTPS,FTP}_PROXY
}
Don't forget to reload .bashrc:
$ . ~/.bashrc
or
$ source ~/.bashrc

This is good answer, but I am afraid that there are more places in the system, when proxy settings needs to be changed: https://askubuntu.com/questions/664777/systemwide-proxy-settings-in-ubuntu.
– matandked – 2017-07-11T10:33:12.040Every software may use its own proxy settings (like npm or apt, to name a few). So http_proxy covers most of them, but you need to check the documentation to be sure which one it uses. – Adriano P – 2017-07-12T15:16:08.307

If you are looking to change the proxy for GUI programs you may have some success if they use the "system" proxy settings from Gnome. These are the proxy settings settable from the Control Panel.
You can look at and then change the the current settings with gconftool:
$ gconftool-2 -a /system/http_proxy
ignore_hosts = [localhost,127.0.0.0/8,*.local]
authentication_user =
authentication_password =
use_authentication = false
use_http_proxy = true
port = 8080
host = http://myproxy.mydomain.org/
To turn off the proxy - set use_http_proxy to false:
$ gconftool-2 -t bool -s /system/http_proxy/use_http_proxy false
You can check the results using the -a
line from above. Alternatively to set a new proxy:
$ gconftool-2 -t string -s /system/http_proxy/host "http://newproxy.mydomain.org/"
$ gconftool-2 -t int -s /system/http_proxy/port 8088
3
export http_proxy=
You can check to see if they are gone by running
echo $http_proxy
It should return a blank line

If all the things written above don't work:
This worked for me!
1The OP asked specifically for a command line option. They might not have installed the GUI – Burgi – 2016-05-27T08:29:40.927

To disable all proxy variables in one line for your current session:
unset `env | grep proxy | cut -d= -f1`
0
You may delete all {http_proxy, https_proxy} etc from /etc/environment. just sudo gedit /etc/environment and then manually delete all those proxies and save.
where do you need to disable it? Proxy settings are application dependant, as far as I know. – Diskilla – 2010-10-05T17:27:16.707
