I need to edit a file like the following:
auto wlx00
allow-hotplug wlx00
iface wlx000 inet dhcp
iface wlx000 inet6 auto
post-up sysctl -w net.ipv6.conf.wlx000.accept_ra=2
auto wlx000
the goal is to delete the lines starting with 'iface...inet' and also delete the next few that start with space (can be none or more than one):
iface wlx000 inet6 auto
post-up sysctl -w net.ipv6.conf.wlx000.accept_ra=2
and keep the rest intact for the following result:
auto wlx00
allow-hotplug wlx00
iface wlx000 inet dhcp
auto wlx000
I tried with sed using as follows:
sed -i.old -r -e "/ifaces*w*s*inet6.*/,$d;/^s.*/d;" /etc/configfile
but it removes everything starting at the right place but erasing to the end. I just want to remove lines staring with space after the select iface text.
bash awk sed

but it removes everything starting at the right place but erasing to the end. I just want to remove lines staring with space after the select iface text.
