Thanks everyone I found all of your refrences helpful. I'm having trouble understanding shift operators. When I run 
qx(dir thisdoesntexist);
print $?;

I get

Running 
qx(dir thisdoesntexist);
print $?>>8;

[download]
returns

1

What does it mean to be shifting bits by 8 and how did that change the return code to 1?

Thank you,

Jason
