I am using Curl, and am having a problem trying to get it to recognize the $http_proxy environment variable when using sudo curl. I tried putting export http_proxy=.... in my /etc/profile and restarting the shell, to no avail. I would rather not use su -l and run the command while logged in as root.

Look in /etc/sudoers. There is a list of environmental variables that get shared between sudo and the regular user shell

You might need to add:

envkeep http_proxy

to your sudoers file. Check your sudo environmental variables by running:

sudo -V

as root. Or by running:

sudo sudo -V
