How to do it with not just 1 slice but 2 slices, and at the same time avoid Merlyn's issue of . and .. not always coming at the start of the list
@l = readdir(PRINT) ; %h{@l} = (1) x @l ; delete @h{'.', '..'} ; for( keys %h ) { # do work }
This is probably not what was desired in the first place, since it adds more lines of code, but I thought this would be interesting.

Nuts and Bolts

  • @l = readdir gets the list of files
  • %h{@l} = (1) x @l converts the list into a hash, since all elements in a directory are unique
  • delete @h{'.', '..'} removes the . and .. entries from the hash at whatever position they're hiding in.
  • for( keys %h) { . and .. free looping
