Here, when I try it against a local webserver, and with the modification I mentioned, I do get a file. However, there's no useful information with the error messages, just a note that there was an error. e.g. HTTP request sent, awaiting response... 404 Not Found 2009-11-15 17:51:32 ERROR 404: Not Found. You'd need to do more to make it list addresses with the errors. wget has options to do with logging, you might want to explore them. See the man file. But if you're doing this to check a website for errors, there are some tools already set up for doing that. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
