-a

turns on autosplit mode when used with a -n or -p. An implicit split command to the @F array is done as the first thing inside the implicit while loop produced by the -n or -p.

perl -ane 'print pop(@F), "\n";'

is equivalent to

while (<>) {
    @F = split(' ');
    print pop(@F), "\n";
}

An alternate delimiter may be specified using -F.
