Hi All,

I have a file in which the contents are as shown below:

Number of Dynamic Addresses Allocated : 107790 Addresses:
10.3.29.202,10.47.1.145,10.2.4.98,190.1.89.95,.. (many ip addresses separated by comma)
----
----

10.38.3.114,10.38.31.12,205.211.32.175,10.18.30.15,200.122.18.29

Number of Static Addresses ......
Addresses:
----

In this file there are static Ips as well but I am interested only in dynamic Ips.

I would like my output should only include Dynamic Addresses in this format

10.3.29.202|10.47.1.145|10.2.4.98|190.1.89.95|.....

What command or script i should write to get only dynamic ips in pipe separated format.

Your help is appreciated.

Thanks
Imas

Another approach:

awk -F, 'NR>1{OFS="|";$1=$1}/Static Addresses/{exit}{print}' file

Hi ranjithPr,

Thank you very much for this piece of code
sed -n '/Number of Dynamic/','/Number of Static/p' f1|grep -v "[a-zA-Z]"|tr "," "|"

It works fine.

Once again thanks a lot.

Also if you could suggest me some book name for learning scripting from abc to programming I will really appreciate.

Thanks
