From 81388f74b58e98d79274a788b442b7a1aa8a11c7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Petr=20=C5=A0tetiar?= Date: Tue, 13 Sep 2022 07:40:37 +0200 Subject: [PATCH] scripts/download.pl: fix downloads with wget MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Several users of wget for downloads (curl is not available in the system) have reported broken download functionality: wget --tries=5 --timeout=20 --output-document=- https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.10.142.tar.xz http://: Invalid host name. Thats all happening due to '' was passed as an argument, which got later expanded to http://. In the context of a list constructor '' is not nothing, it is an empty string element. So fix it by using () as it will yield "nothing" and thus not introduce an empty string element.
