A remind:

  • /etc/environment is not a script. It only supports KEY=VALUE syntax ($variable is not supported either)
  • /etc/profile does not support export {HTTP,HTTPS,FTP,RSYNC,ALL}_PROXY=$http_proxy, it may hang your login

it needs to be git config --global core.sshCommand "ssh -o '$ssh_proxy'" because gitconfig ignores double quotation marks

What is the syntax to use a socket file instead of IP:PORT as my proxy?
