It runs through a file making edits. The -i option allows you to change a file in place. s/foo/bar will SUBSTITUTE (s) the phrase 'foo' with replacement 'bar' So that first command in dom0 went through the file /etc/yum.repos.d/qubes-dom0.repo and on every line where it found: yum.qubes-os.org changed it to: yum.qubesos4z6n4.onion and then saved the changed file. Instead of the sed command, the instructions could say: 1. Open the file /etc/yum.repos.d/qubes-dom0.repo in your favourite text editor. 2. Look for every occurrence of yum.qubes-os.org, and change it to yum.qubesos4z6n4.onion. 3. Save the changed file. If you really want to set it back you can either reverse the sed command, or make the changes manually in a text editor. That is: 1. Open the file /etc/yum.repos.d/qubes-dom0.repo in your favourite text editor. 2. Look for every occurrence of yum.qubesos4z6n4.onion and change it to yum.qubes-os.org. 3. Save the changed file. Do the same for the other file. That's reversed the changes you made. The two variables that "dont exist" are just placeholders for the name of the template that you want to change. So instead of $DebianTemplateVM type in the name of the Debian template that you want to affect. The qvm-run command allows you to run programs on qubes from dom0 - in this case, using sed allows you to change those files quickly from dom0 instead of opening the TemplateVM, firing up a text editor and making the changes in the TemplateVM. What's puzzling is that you find that you can't connect to the update servers anymore. (I assume that you mean from dom0 because you didnt make any changes in Templates.) It occurs to me that it doesn't actually say on the page that you will need your updateVM to be running behind a Tor gateway for this method to work. Perhaps you knew this? Perhaps not. You should ensure that you made this change - if your updateVM is NOT running through Tor then updates will always file. If it IS then they will fail some of the time - that seems to be inevitable using Tor. If you really do want to revert then you dont need to worry about this. Just revert the changes you made in the .repo files and things should work again. unman unman -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

You may simply use sed ("stream editor") the other way: syntax is sed -i 's/SEARCH/REPLACE/' So the first command reverted will contain sed -i 's/yum.qubesos4z6n4.onion/yum.qubes-os.org/' Bernhard -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
