fetch(1) has got a special `-a' option that allows automatically retrying a transfer upon soft failures. But if, for example, a server returns HTTP error "403 Permission Denied", fetch(1) will loop forever trying to repeat the request. It's useful to have an opportunity to control such behaviour. How-To-Repeat: % fetch -a http://foobar.com fetch: http://foobar.com: Forbidden fetch: http://foobar.com: Forbidden fetch: http://foobar.com: Forbidden fetch: http://foobar.com: Forbidden fetch: http://foobar.com: Forbidden ^Cfetch: transfer interrupted With a new `-e' option we can limit a number of retries: % fetch -e 2 http://foobar.com fetch: http://foobar.com: Forbidden fetch: http://foobar.com: Forbidden fetch: http://foobar.com: Forbidden
