Depends where in the array you want to cut stuff out and if you're rmoving a single element at a time or multiple elements... splice is the most general (i think any shift or pop can be re-written as a splice), whereas shift and pop only remove a single element, and only from the very front or back (respectively) of the array. perldoc -f splice perldoc -f shift perldoc -f pop so, to summarize: if only one element from front, then shift else if only one element from back, then pop else splice (Note also there are probablly different ways besides splice as well -- e.g. could probably rewrite using map/grep/array slices)
