Re^5: How to tell if a Directory is Empty

glob, unlike readdir, does not look for "hidden" files unless you explicitly include them in the pattern. And if you do so, you'll find also the standard directory entries . and ..:

/home>cd /tmp/
/tmp>mkdir foo
/tmp>cd foo
/tmp/foo>touch .hidden
/tmp/foo>perl -E 'die "oops" unless !!<*>'
oops at -e line 1.
/tmp/foo>perl -E 'say for <*>'
/tmp/foo>
/tmp/foo>perl -E 'say for <.*>'
.
..
.hidden
/tmp/foo>
