Composition naming

I would like to check all the compositions in the project panel for a specific name. For example, if I would like to copy a composition with the name "Comp 1". I would like to check if there is the composition with the name "Comp 1" and added suffixes "dup_1", "dup_2". "dup_3". If there is one my goal is to increment the last number. So the second time I copy the composition it would end with "dup_2". "dup_3" "dup_20" etc. Could you help with with these code?

Play around with this:

function getUniqueCompName(theName,theSuffix){
	var n;
	var maxN = 0;
	var splitText;
	var curComp;
	var n;
	for (var i =1; i <= app.project.numItems; i++){
		if ((app.project.item(i) instanceof CompItem)  && (app.project.item(i).name.indexOf(theName) == 0)){
			curComp = app.project.item(i);
			idx = curComp.name.indexOf(theSuffix);
			if (idx > -1){
				n = parseInt(curComp.name.substr(idx + theSuffix.length),10);
			}
			if (! isNaN(n)) maxN = Math.max(maxN,n);
		}
	}
	return (theName + theSuffix + (maxN + 1));
}

getUniqueCompName("Comp 1", "dup_");

Thank you Dan, this is great. However, I have one problem, If the comp name ends with _dup. The script is actually adding only one _dup _dup_1, every time it's run, so it won't iterate through numbers. The name of the comp always stays the same and ends with _dup _dup_1. Can you help me with this?

You lost me. Can you give an example of what comp names you have and what name you expect when you run the script?
