cd /opt/AMD-APP-SDK-v2.4-lnx64 running in xterm changes to that folder.
But tar icd-registration.tgz -C / gives error, saying
tar: you may not specify more than one 'Acdtrux' or '--test-label' option
Try 'tar --help' or 'tar --usage' for more information.
What do to?
I believe this is a typo and you should use "tar -xzvf icd-registration.tgz -C /" or something like that. The flags for unzipping the tgz are missing form the command.
