-----------------------------
#!/usr/bin/perl
# this just re-implements tail -1
#
# usage:
# /this/file < /some/text/file.txt
#
my $last;
while( <> ) {
$last = $_;
}
print $last;
-----------------------------
Now, try with the "my $last;" *inside* the while(). That last print
line won't have a clue what $last is.
