How To Save A File In Vim / Vi Without Root Permission With sudo

Originally published at: https://www.cyberciti.biz/faq/vim-vi-text-editor-save-file-without-root-permission/

This happens lot of times. I login as a normal user and start to edit httpd.conf or lighttpd.conf or named.conf in vim / vi text editor. However, I’m not able to save changes due to permission issue (all config files are owned by root). How do I save file without creating a temporary file (/tmp/httpd.conf) and then move the same (mv /tmp/httpd.conf /etc/httpd) as root using vim / vi itself?
