Question about IO redirection
for shell operators like <, >, <<, and >> do the LHS always have to be a process or device and the RHS a file or device?
Is it possible for the RHS to be a process?

Hi,
in my script I need to execute the following command:
query $id 456 432
but it waits for a RETURN character from keyboard and therefore, it fails. I tried something like:
query $id 456 432 << '\n'
but, i'ts clear it is not correct. Is there any way to do this?

Hi,
Can I get some explanation around this bash redirection?
From what I have read, x < y means call the shell to redirect the output of y into x.
Does this mean that this sequence of commands is executed from right to left?

TAU_MAPPING_OBJECT(3) TAU Mapping API TAU_MAPPING_OBJECT(3)
NAME
TAU_MAPPING_OBJECT - Declares a mapping object
SYNOPSIS
C/C++:
TAU_MAPPING_OBJECT(FunctionInfo FuncIdVar);
DESCRIPTION
To create storage for an identifier associated with a higher level statement that is mapped using TAU_MAPPING, we use the
TAU_MAPPING_OBJECT macro. For example, in the TAU_MAPPING example, the array expressions are created into objects of a class
ExpressionKernel, and each statement is an object that is an instance of this class. To embed the identity of the statement we store the
mapping object in a data field in this class. This is shown below:
EXAMPLE
C/C++ :
template<class LHS,class Op,class RHS,class EvalTag>
class ExpressionKernel : public Pooma::Iterate_t {
public:
typedef ExpressionKernel<LHS,Op,RHS,EvalTag> This_t;
//
// Construct from an Expr.
// Build the kernel that will evaluate the expression on the
// given domain.
// Acquire locks on the data referred to by the expression.
//
ExpressionKernel(const LHS&,const Op&,const RHS&,
Pooma::Scheduler_t&);
virtual ~ExpressionKernel();
// Do the loop.
virtual void run();
private:
// The expression we will evaluate.
LHS lhs_m;
Op op_m;
RHS rhs_m;
TAU_MAPPING_OBJECT(TauMapFI)
};
