Hi all,

Input:

a
a

d
TEST
f
e
g
g
TEST

Output:
a
a
c
f
d
f
e

g

Could anyone help me in this please.

You want to extract the data between TEST and TEST pairs? If so, what about the next TEST?

Yes. I need to read the data between the TESTs and pull out some information.
There will be may TESTs in the file..So, till the last TEST, i need to do this

So, you just want to suppress TEST and print the data? I guess NOT

Code:
#input
TEST
a
b
c
TEST
1
2
3
TEST
d
e
f
TEST
 
#output
a
b
c
d
e
f

Like this? will there be even number of TEST in your file to define the boundary?

No. I don't want to suppress. Based on the boundaries (TEST), i should again loop the line and pull some data (with grep etc..).

No. I will not have any clue how many TESTs i will have. May, be we can achieve the number of TESTs we have in the file if we need the boundary limit.

Post a valid input file and expected output and we can work it out!

Based on your input and output, the below line should achieve what you want.
Code:
grep -v "TEST" input.txt
