I'm using this script to update my hosts file with ad blocking settings.
#!/bin/bash
# Hosts file updater
HFSERVER="http://hostsfile.mine.nu.nyud.net"
HFILE="hosts.zip"
ORIGFILE="/etc/hosts.original"
clear
echo "-------------------------------------------------------------"
echo "This script will update your Hosts file to the latest version"
echo "Your original Hosts file will be renamed to $ORIGFILE"
echo "-------------------------------------------------------------"
echo ""
if [ ! -f "$ORIGFILE" ] ; then
echo "Backing up your previous hosts file.."
cp -v /etc/hosts $ORIGFILE # I like verbose file operations. Can be less verbose if necessary.
fi
echo "Retrieving $HFILE from $HFSERVER"
echo ""
wget -O /tmp/$HFILE $HFSERVER/$HFILE
unzip -p /tmp/$HFILE | dos2unix > /tmp/hosts
if [ 'grep -c "banner" /tmp/hosts' ];then
echo "Downloaded and unpacked $HFILE OK"
echo "Appending host list to original content" # which was probably there for a reason, like to make sure localhost worked, and possibly even more stuff if part of a corporate LAN
#cp -f -u /tmp/hosts /etc/hosts
cat $ORIGFILE >/etc/hosts
echo "" >>/etc/hosts # to make sure the original file ends in a new-line so that 2 entries don't end up on the same line, either causing unexpected behavior or not working at all
cat /tmp/hosts >>/etc/hosts
rm -fv /tmp/hosts* # again, I like verbose file operations. I like to know what my system is doing.
echo "Update process complete"
#echo "-------------------------------------------------------------"
echo "As a side-effect of this script, any changes you wish to make"
echo "persistent in the hosts file should be made to $ORIGFILE"
echo "because /etc/hosts will be respawned from that file and the "
echo "newlist from the server each time this script runs."
exit
else
echo "Update failed"
fihttp://hostsfile.mine.nu/downloads/updatehosts.sh.txt
And my hosts file now looks like this:
#
# /etc/hosts: static lookup table for host names
#
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 localhost.localdomain localhost pote

127.0.0.1 localhostSince localhost is already stated here:
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 localhost.localdomain localhost poteFor now I've deleted the redundant localhost entry, since it seems to be there for windows compatability.
Is there any harm in leaving that entry?

Not as far as I know.
It probably just re-encounters the localhost hostname and either dumbly re-adds it to the internal table or ignores it. In any case, no logically discernible harm done.

Windows was made for looking at success from a distance through a wall of oversimplicity. Linux removes the wall, so you can just walk up to success and make it your own.
