⁠3.5. Validating in Linux

Open a terminal emulator:

on the GNOME desktop, click Applications → System Tools → Terminal to open GNOME Terminal
on the KDE desktop, click Kickoff Application Launcher → Applications → System → Terminal to open Konsole

Change into the directory that holds the ISO image files, then run sha256sum, for example:

$ cd Downloads
$ sha256sum Fedora-18-i386-DVD.iso

Open the file CHECKSUM with a text editor, such as gedit or kwrite, to display its contents. Make sure the hash displayed by sha256sum for each of the downloaded ISO files exactly matches the corresponding hash in the CHECKSUM file.

If all of the hashes match the hashes found at http://fedoraproject.org/verify, you can burn the ISO file to disc. If a file does not match, download it again.
