Script is working flawlessly on my box although only one record is returned. I notice that you have a number of occurrences of:

----------------- NMInterface --------------
+++++++++++++++++ NMInterface ++++++++++++++

and not only

============ Interface Information ====================
+++++++++++++++++ NMInterface ++++++++++++++


Not the same record separator.

Which version of awk do you have?

$ awk --version

Yes, But my requirement is,

Whenever the string matches "+++++++++++++++++ NMInterface ++++++++++++++" then It should print upcoming line of 3rd line, 8th line and 21st line. (No need to consider the above line in any of the text pattern)

I already have same kind of script that will print Whenever the string matches "+++++++++++++++++ Interface ++++++++++++++" it's printing next 5 lines.
#!/bin/sh
awk ' $0 ~ /\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+Interface\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+\+/ {
match_str="YES"; line_cnt=0; next; }
{
if((line_cnt < 5) && ( match_str=="YES"))
{
print $0;
line_cnt += 1;
}
else {
match_str="NO"; line_cnt=0; }
}' <Input_File>

Pls. guide me now.
Thanks,

Right. Try this:

Code:
$ awk 'BEGIN {RS="\++ NMInterface";OFS=FS="\n";ORS="\n\n"} {print $4,$9,$22}' your.file

But in that case the 21th line doesn't always return what you expect:

Code:
EntityName:aust00m1.mis.amat.com[ 0 [ 255 ] ]
OverallStatus:Normal
IfName:AT9/1/0.145

EntityName:aust00m1.mis.amat.com[ 0 [ 256 ] ]
OverallStatus:Normal
Capability: 

EntityName:aust00m1.mis.amat.com[ 0 [ 257 ] ]
OverallStatus:Normal
IfName:AT9/1/0.315

EntityName:aust00m1.mis.amat.com[ 0 [ 258 ] ]
OverallStatus:Normal
Capability: 

EntityName:aust00m1.mis.amat.com[ 0 [ 259 ] ]
OverallStatus:Normal
IfName:AT9/1/0.325

Still have the same pbl with awk?

Hi Ripat,

Thank you so much for your hard work on my requirement. I'm looking for an alternate way to achive my requirement. Because It's not giving proper info on 21st line.

I will get back on the forum after I find an alternate way to grep my info.

Thanks for your support, Thanks all

Don't give up! If the 3rd info is not always on the 21st line, there is a work around. Try this:
Code:
#!/bin/bash 
awk '
BEGIN {RS="\++ NMInterface";OFS=FS="\n";ORS="\n\n"}
{match($0, /IfName:[^\n]+/, out);print $4,$9,out[0]}' your.file

Ripat,

How to run this file?

I'm using HP-UX 11.23

First I copied all those your commands to file 'int'
then executed,
Error:
# ./int
syntax error The source line is 3.
The error context is
{match($0, >>> /IfName:[^\n]+/, <<<
awk: The statement cannot be correctly parsed.
The source line is 3.


Then I changed to bash.
then executed,
ERROR:
# bash
# ./int
Segmentation fault (core dumped)

How to resolve this issue?

Thanks,
Gobinathan.S

The third element of the match() function is a GNU awk extension. How about this:

Code:
#!/bin/bash 
awk '
BEGIN {RS="\++ NMInterface";OFS=FS="\n";ORS="\n\n"}
{print $4,$9,substr($0, match($0, /IfName:/), 18)}
' your.file
