in reply to Checking if an item exists in an array before adding a record to it.

I suspect using grep would be even slower.

  • either use grep on the array if you want to check if something's already in it as you suggest yourself
  • or throw the dupes out when you are done populating the array (if order does not matter)
  • or (again if order does not matter) use a hash all the way through and use keys %hash to get a list of unique entries instead of the array.
