How to fetch a string between two different strings
Hi Scrut,

Thanks, I understand that RS record sperator and FS is field ..
It is little confusing to me here that how exactly awk is understanding record here and then using FS to get value.

Can you please let me know from this example?

Record1=?

Record2=?

Thanks
Krsna

-F"[><]" --> we are giving two field seperator >< ( if any one occurs, then field will be seperated )

Hi, Krsna, maybe this helps:

Code:
$ awk '{print NR,$0}' RS=\< infile
1 
2 name>usrname
3 /name> 
4 value>ravistej
5 /value>

6 name>pswd
7 /name> 
8 value>asdfgzxcv
9 /value>
.
.
.
.

10 name>abc
11 /name> 
12 value>xyz
13 /value>

Code:
$ awk '/^value/{print NR,$0}' RS=\< infile
4 value>ravistej
8 value>asdfgzxcv
12 value>xyz
