From 0ac6bf5a973159117c2457bf27e5c7b554f112ca Mon Sep 17 00:00:00 2001 From: Charles Lehner Date: Sat, 9 Jan 2016 14:18:53 -0500 Subject: Reload on SIGHUP This patch makes surf reload its pages when it receives a SIGHUP signal. This makes it easier for shell scripts to trigger surf to reload. I'm aware of using xdotool to trigger ctrl+r keypresses for reloading [1] but I wasn't able to get that to work in a general way. I'm sending this here in case surf maintainers and users would like to include this in core - if not I will submit it to the wiki.
