and in some other places...
but still work well! Thank you!!
...and maybe you should drop non-unique addresses
to remove non-unique lines we can use this bash-script
cp /etc/hosts /etc/hosts.before-uniq.bak
grep -o '^[^#<]*' /etc/hosts | sort | uniq > /etc/hostshere:
grep -o '^[^#<]*' -- prints only lines not containing # or <at the beginning of the line
Hi,
thanks for the correction...This script is pretty old, so the main reason why we see html/http output there is because the host files moved the server location, so if the URLs get updated it should work again...
Btw nowadays I use this:
https://github.com/StevenBlack/hosts
It's much more feature rich and can be nicely configured...
