Shift Operators Binary "<<" returns the value of its left argument shifted left by the number of bits specified by the right argument. Arguments should be integers. (See also Integer Arithmetic.) Binary ">>" returns the value of its left argument shifted right by the number of bits specified by the right argument. Arguments should be integers. (See also Integer Arithmetic.) Note that both << and >> in Perl are implemented directly using << and >> in C. If us

The first number is the one returned by getgid() , and the subsequent ones by getgroups() , one of which may be the same as the first number. However, a value assigned to $( must be a single number used to set the real gid. So the value given by $( should not be assigned back to $( without being forced numeric, such as by adding
