grep or sed help for a word and an IP address

I would like to grab only designates and the IP address next to it. I can also live with client-ip=xx.xx.xx.xx

Any help is much appreciated.

line to grep or sed:

Received-SPF: pass ( domain of designates as permitted sender) client-ip=;

Received-SPF: pass ( domain of designates as permitted sender) client-ip=;

awk '{print $7,$8}' file_name

hope you wanted this.

Thanks Sanjay, but I only gave you a snippet of the file, and the file has many different types of entries and information, so awk will not work as the fields numbers will change.

My guess:

[house@leonov] cat test.file | grep "designates" | \
  egrep -o "[0-9]{2}.[0-9]{2}.[0-9]{2}.[0-9]{2}" | uniq

you can use this :

egrep -o "designates............" file_name


cat filename|tr -s " "|egrep -o "designates............"

I like that. I'll have to remember that! It works great and it is simple. Thanks Sanjay.

presumably faster because of no pipelines and only one process:

sed -n 's/^.*\(designates \([0-2]*[0-9]*[0-9]\.\)\{3\}[0-2]*[0-9]*[0-9]\).*$/\1/p' /your/input/file

Depending on what your convention for storing IP adresses is (is "" stored like this or like ""?) the above regexp for IP adresses could probably narrowed down a little further.

I hope this helps.
