My file is having the contents like this

AND1 (A) {
non : hafe
on: tc
ma : nite }

AND1 (B) {
non : hafe1
on: tc1
ma : nite1 }

AND1 (C) {
non : hafe3
on: tc2
ma : nite3 }


I have written a sed script to search the patterns AND1(A) and AND1 (B) and delete the entire content in these Blocks including the Patters AND1 (A) and AND1 (B)

but to my surprise the whole file content is getting deleted

This is my sed script

sed -n '/AND1 (A)/,/AND1 (B)/ { /non/d ;}'file > file1

My new file content should be

AND1 (C) {
non : hafe3
on: tc2
ma : nite3 }

but the whole file is getting deleted

Can someone give me advice ?

use awk

Thanks actually that soultion actually worked .

I am having another issue with my awk script

Contents of my file is like this
file
AND (P1) {
no : and ;
mo : band ;
co : land ;
}

OR (P2) {

no : sand ;
cling : dad ;
Fiend : salt ;

}

NAND (P3)

no : sat ;
to : jat;
pi : tad;
}


What I need to do I need to search the patterns AND (P1) and OR (P2) and then delete all the contents of this Block and insert the content from another file - file2 ( between P1 and P2 ) in this location.


What I am doing ; I am inserting the code first


awk '{ if($0 ~ /P1/) {set=1; next}; if( $0 ~ /P2/) {set = 0}; if (set ) { print }}' file2 | awk '/AND (P1)/{f=1}f && /}/{print; system("cat $1");f=0;next}1' file > newfile

file2 content
############
P1

AND is the the band
land is the and

P2

#############

After this To delete the blocks I could use
sed '/AND/,/OR/d' file

I am having two issues here
1. The code will be inserted after the AND (P1) Block I want the code to be inserted before AND (P1) Block so that I can delete the respective blocks after that
2. By using the command sed '/AND/,/OR/d' file
I will delete not full contents
It will delete only these entities

AND (P1) {
no : and ;
mo : band ;
co : land ;
}

OR (P2) {


Need some advice in this regards
