From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Be cautious of doing this with security sensitive files. When it copies the file and gives you ownership, any sensitive data in it is exposed to any process running as your user id, and and temporary fil£s the editor creates may also contain the sensitive content and be owned by you.
Good point. I was always wondering how secure this is, as it works with copies of the files in my environment. Because I'm in my personal environment, doing
sudoedit /etc/fstab
does not let me edit other files from root while in that file. That means if any of the plugins from Vim tries to, they can't edit arbitrary files, right? (If you don't trust the plugin, then don't use, but that's another topic.) Little side note, just learned thatsudoedit ~/.bashrc
does not allow me to edit files in my home too.Vim is running as you, rather than root, so you wont be able to edit other files as root, and any rogue plugins wont be able to either, which is good.
Sudoedit has various guards around what it'll let you edit, in particular, you can't edit a file in a directory you already have write permission on as doing so allows the user to bypass restrictions in the sudoers setup (there's more detail in their issue tracker. If the directory is already writable though, you don't need sudoedit anyway.
