Help required in searching of pattern.
i m searching a zone file my domain name is abcd.com


my zone file looks like this.

Code:
abcd.com.       IN      SOA     ns1.abcd.com.      root.abcd.com. (
               

abcd.com.               400     IN      A       15.1.1.1

Then i am searching that abcd.com have if below ip address or not, if not then echo ip address is different. But problem is that i am not able to search the domain name with ip address because domain name is also having SOA record. abcd.com.zone is file name of zone file.

Code:
grep ^abcd.com. abcd.com.zone  | fgrep 15.1.1.10 | awk {'print $5'}

Not sure what you want. Would this do the job:
Code:
grep -q "^abcd\.com.*15\.1\.1\.10" file && echo zone-IP found || echo ip address is different.

?

I don't think so, as you need the regex .*. fgrep would look for fixed strings only.

Note that the command:
Code:
grep -q "^abcd\.com.*15\.1\.1\.10" file && echo zone-IP found || echo ip address is different.

will also say that the IP was found for IP addresses 15.1.1.100 through 15.1.109 in addition to 15.1.1.10. Assuming there is no whitespace at the end of the line, you might want to try:
Code:
grep -q "^abcd\.com.*15\.1\.1\.10$" file && echo zone-IP found || echo ip address is different.

instead.
