Hi,

In my hosts file, the last line is as follow
197.2.23.134      truc TRUC

I want to write a script to get the this IP address.
What command in sed or awk to execute this ?

Thank you so much

I see that you've gotten a couple of answers already. However, in the interests of "There's more than one way to do it", here's another approach:

grep truc /etc/hosts | grep -o "[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}"

or

grep truc /etc/hosts | grep -o "[0-9]*\.[0-9]*\.[0-9]*\.[0-9]*"

or

grep truc /etc/hosts | cut -f1 -d" "

I'm sure that there are others. :)

Ben
