Push and Pop

To add or remove an item from the “high” (right) side of the array, use push or pop.

• push(@list, $newItem);
• $value = pop(@list);

Shift and Unshift

To do the same at the “low” (left) side use shift and unshift.

• $item = shift(@list);
• unshift(@list, $item);
• You can push or unshift more than one item at a time.

Reverse and Chomp

You can reverse the items in an array with the reverse function.

• @rev = reverse(@list);
• @list = reverse(@list);

The chomp function will remove the last record separator of each element.

• When an array is the destination of an input stream, an array variable will read in the entire file.
• See programs under perl/arrays.
