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_PROFILE(3) TAU Mapping API TAU_MAPPING_PROFILE(3)
NAME
TAU_MAPPING_PROFILE - Profiles a block based on a mapping
SYNOPSIS
C/C++:
TAU_MAPPING_PROFILE(FunctionInfo *FuncIdVar);
DESCRIPTION
The TAU_MAPPING_PROFILE macro measures the time and attributes it to the statement mapped in TAU_MAPPING macro. It takes as its argument
the identifier of the higher level statement that is stored using TAU_MAPPING_OBJECT and linked to the statement using TAU_MAPPING_LINK
macros. TAU_MAPPING_PROFILE measures the time spent in the entire block in which it is invoked. For example, if the time spent in the run
method of the class does work that must be associated with the higher-level array expression, then, we can instrument it as follows:
EXAMPLE
C/C++ :
// Evaluate the kernel
// Just tell an InlineEvaluator to do it.
template<class LHS,class Op,class RHS,class EvalTag>
void
ExpressionKernel<LHS,Op,RHS,EvalTag>::run() {
TAU_MAPPING_PROFILE(TauMapFI)
// Just evaluate the expression.
KernelEvaluator<EvalTag>().evalate(lhs_m,op_m,rhs_m);
// we could release the locks here or in dtor
}
