Can you tell me what does this do?

"int(i)){i+=0.5}1"

What can I change if I want it to do every 3 instances or maybe start like at 4000 for the integer?
Explanation:
Code:
gsub("PORT",int(i))

substitute all instance of PORT in the current line with the integer of i
Code:
{i+=0.5}1

increase i with 0.5 and print the line

This approach suites for 2 instances:

Quote:
int(0) gives 0
int(0.5) gives 0
int(1) gives 1
int(1.5) gives 1
etc.
If you don't have to much substitutes, you can try some thing like for 3 instances if you want to start with 4000:

Code:
awk -v i="4000" '/PORT/ && gsub("PORT",int(i)){i+=0.33334}1' file
