Sort command

In Pine's generic configuration, messages are presented in the order in which they arrive. This default can be changed your Pine configuration in the sort-key section. You can also re-sort the folder on demand with the sort ($) command. Sorting a folder does not actually rearrange the sequence of message in the folder they are saved in, it just re-arranges how the messages are presented to you. This means that Pine has to do the work of sorting every time you change sort order. Sometimes, as with large folders, this could take a while.
