Looking for standard lines inside file using REGEX

[viadisky]

Hi,

I need the help of all regex gurus out there.

Listed below are standard lines I need to check inside a file. A file should be okay if all these lines can be found and in the right order.

ip name-server 4.3.2.1
ip name-server 3.2.3.2
ip name-server 1.1.1.1

I created a very basic REGEX to do this:

^ip name-server 4\.3\.2\.1$
^ip name-server 3\.2\.3\.2$
^ip name-server 1\.1\.1\.1$

If additional "ip name-server <IP Address>" will be placed on top or below the standard lines, the REGEX I created won't be able to see these lines.

Can anybody suggest an easy way how to modify my REGEX?

Try this

^ip name-server \d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$

I never set a goal because u never know whats going to happen tommorow.

Hi Spookie,

Thanks for the suggestion you provided
But this REGEX matched the file with these lines:

ip name-server 172.21.204.33
ip name-server 172.21.204.34
ip name-server 1.1.1.12

That's why I had to type the exact IP Addresses to have 100% match.

If you are matching exact lines why would you use a regexp?

Why not just look for those specific lines..
