Comment 95 for bug 1452202

Hi Eric,

I think your proposal '-w' is good, so I will change to use:

if ! echo "$RET" | grep -qw 'ubuntu'; then

Mathieu,

How about using '/b' ? I mean using the following regex

/bin/sed -i "s/\b${CURRENT_HOSTNAME}\b/${NETCFG_HOSTNAME}/g" /etc/hosts

I have done some test below:

hua@t440p:~$ echo "node" | sed "s/\bnode\b/newnode/g"
newnode
hua@t440p:~$ echo "node." | sed "s/\bnode\b/newnode/g"
newnode.
hua@t440p:~$ echo "node.me.com" | sed "s/\bnode\b/newnode/g"
newnode.me.com
hua@t440p:~$ echo "ipv6-allnodes" | sed "s/\bnode\b/newnode/g"
ipv6-allnodes
hua@t440p:~$ echo "ipv6-allnodes node node.me.com node2 node2.me.com" | sed "s/\bnode\b/newnode/g"
ipv6-allnodes newnode newnode.me.com node2 node2.me.com

any thoughts ?
