The output should be like this:
Code:
line_before_pin_1
line_before_pin_2
..
line_after_pin_1
line_after_pin_2
PIN
line_after_pin_3
..
line_after_pin_end

Note that there are 2 actions:
- remove old PIN line
- add new PIN line to the right position
Hello fongthai,

Could you please try following and let me know if this helps you. Let's say your Input_file is as follows.
Code:
cat  Input_file
line_before_pin_1
line_before_pin_2
PIN
line_after_pin_1
line_after_pin_2
line_after_pin_3
line_after_pin_end

Then following is the code for same.
Code:
awk -vxyz=2 '{if($0 ~ /PIN/){while(++a<=xyz){getline;print $0;};print "PIN";a="";next}} 1'   Input_file

Output will be as follows.
Code:
line_before_pin_1
line_before_pin_2
line_after_pin_1
line_after_pin_2
PIN
line_after_pin_3
line_after_pin_end

Similarly you could change the value of variable in above code -vxyz=2to as per your requirement too.

Thanks,
R. Singh
