That's why the usual filters such as 'sed' are going to have a hard time of it. You need to capture each number as it comes out and process it (throwing away the ^H i.e. backspace characters) even though you haven't seen a newline yet, because by the time you see the newline the file has finished. (This is a clear indication that the program was originally written for a non-Unix environment, since the author just assumes that the progress is for display on a terminal and not for filtering). I'm not saying it's impossible, just nasty. You might be better tweaking the source of unrar to give you more manageable output. You probably can't distribute the result though (the license is freeware, not free). poc -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
