Double quotes are giving me trouble.
I have a file with a line in it like this
ip4="10.111.098.2"
I want to get just the ip address
ip=`grep "ip4=" directory-path/file-name
$ip ends up having ip4="10.111.098.2" in it
ip=`echo -n "${ip}" | tr -d "ip4="
$ip ends up having "10.111.098.2" in it
Putting | tr """ " "` after the echo above gives error.
How do I remove the " around the ip address?
