[OpenWrt-Devel] [PATCH] Fix regular expression in sysupgrade

[Преподобный Гомер]

Previous regular expression in sed allowed strings that starts with space.

$ cat sysupgrade.conf
## This file contains files and directories that should
## be preserved during an upgrade.

# /etc/example.conf
 # /etc/openvpn/
/etc/config
/etc/profile
/etc/firewall.user
/etc/TC_hfsc.sh
/etc/hotplug.d/iface/30-trafficc
/etc/init.d/trafficc
/root
/etc/crontabs/root
$ sed -ne '/^[[:space:]]*$/d; /^#/d; p' sysupgrade.conf
 # /etc/openvpn/
/etc/config
/etc/profile
/etc/firewall.user
/etc/TC_hfsc.sh
/etc/hotplug.d/iface/30-trafficc
/etc/init.d/trafficc
/root
/etc/crontabs/root

This patch fixes that problem
$ sed -ne '/^[[:space:]]*\($\|#\)/d; p' sysupgrade.conf
/etc/config
/etc/profile
/etc/firewall.user
/etc/TC_hfsc.sh
/etc/hotplug.d/iface/30-trafficc
/etc/init.d/trafficc
/root
/etc/crontabs/root
