[BBLISA] silly unix 'ls' question

[Jeff Ambrosino]

It pains me to have to ask this question, but I can't find this
anywhere is man pages or other online docs...  when you run "ls -l"
what do the two numerical columns represent for directory entries?  I
know they mean hardlinks and bytes for _files_, but what are they for
directories?

e.g.:

drwxrwxrwx   1 root  root    3813688 Aug  1 14:09 MyDirectory

So what are the "1" and "3813688" numbers?

thanks & stay cool,
JB
