Match exact Variable in Awk
I want to match exact string stored in Variable INO and print next two lines. I have written below code which partially matches:

Code:
awk '/\'$VAR'/{getline; getline; print}'

Will be thankful , if somebody can help in to resolve this problem.

What is "not working"?

Please post a representative sample of input and the expected output.

What about:
Code:
~/unix.com$ awk -v var='text2' '$0==var{getline x;getline;print x RS $0}' file

set var to search what you want for
Code:
~/unix.com$ cat file
text1
text2
text3
text4
text5
~/unix.com$ awk -v var='text2' '$0==var{getline x;getline;print x RS $0}' file
text3
text4

If it supports -A, just use grep. It'll also handle the case where the pattern matches within two lines of the previous match (if that's a possible scenario, the AWK solutions above will not handle it correctly).

Hi,

Here is the sample example:


Code:
var=$(echo $i | cut -s -d. -f1 )

Where i contains a:2.b:3

I have an output as follows :

Code:
  b:2 a:2
  a
  b
  b:22 a:22
  c
  d

I want to print only b which is at next to next line of pattern a:2.

I am using
Code:
awk '/\'$var'/{getline; getline; print}'

but it prints b and d both, as it matches a:2 and a:22 .
