What does ">>" do? (And other stat questions)by three18ti (Scribe)

three18ti has asked for the
wisdom of the Perl Monks concerning the following question:
I'm looking to search for files and directories with "777" permissions, so I'm reading the stat manpage. I think I know HOW to use the module, but I really don't understand.
for instance, the first example is:
I can modify this to be usable:
I'm sure there are other problems, besides using a magic number, but can someone explain what "&07777" does? (I also don't understand sprintf, but I understand that it takes a sort of "template" and produces results)
The next example is using Fcntl to import symbolic constants. But the examples are using some Perl magic I have not encountered before:
My GUESS is that the "&" and ">>" are some sort of binary operators, but I get whatever the users mode is. Can someone please explain what is going on here as well? What is ">>" ? (I tried to google, but couldn't figure out how to search for the symbols or what to call them by name.
