Linux users normally edit configuration files with terminal-based tools like nano and vim . If you want to edit a file graphically—even a system file—the gedit text editor makes it painless and easy.
Files, Files Everywhere
An oft-repeated phrase concerning Linux and other Unix-based operating systems such as macOS is “everything is a file.”

It’s a handy tool for editing files when all you need is just enough editor to get the job done—without the learning curve of some of the power-house editors like vim.
