I looked at the manual for ls and it says that -1 "Prints one entry per line of output".

At what point does the sorting occur?
Hi.

The sort order of ls is alphabetical by default.

By using -1 it does print one entry per line, then tail -1 will take the last one (i.e. the newest by timestamp).

But you don't even need the -1:

Code:
$ touch AA_20100806.dat AA_20100807.dat AA_20100808.dat AA_20100809.dat AA_20100810.dat AA_20100811.dat AA_20100812.dat
$ ls
AA_20100806.dat	AA_20100807.dat	AA_20100808.dat	AA_20100809.dat	AA_20100810.dat	AA_20100811.dat	AA_20100812.dat
$ ls | tail -1
AA_20100812.dat

load_datafile(3alleg4)						  Allegro manual					    load_datafile(3alleg4)

NAME
load_datafile - Loads a datafile into memory. Allegro game programming library. SYNOPSIS
#include <allegro.h> DATAFILE *load_datafile(const char *filename); DESCRIPTION
Loads a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example: /* Load the resources for our game. */ DATAFILE *dat = load_datafile("game.dat"); if (!dat) abort_on_error("Couldn't load sound resources!"); /* Use resources. */ ... /* Destroy them when we don't need them any more. */ unload_datafile(dat); RETURN VALUE
Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks. SEE ALSO
