xzcat Fedora-Minimal-armhfp-20-1-sda.raw.xz | sudo dd of=/dev/sdb Will also work, using sudo to grant write permissions, but not read permissions. Less flexible than specifying a command to a sudoed shell command, but also more granular control (if you can call dd as root granular). -- imalone http://ibmalone.blogspot.co.uk -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
