Redirection operator does not work. So how should we do it? One more question, in makefile, how can we give arguments from command line, like
run: a.out
./a.out **<input>**

A:
gcc prints its error messages to stderr, so you have to redirect stderr:
gcc -o foo foo.c 2> foo.gccmessages
You give arguments on the command line always in the same way
./a.out argument1 argument2 argument3

In makefile, I want to specify that input will be given from command line.I am not asking how to give input at command line? How to do that?

You do that by asking a separate question and getting answers to it.

Ok I got that, if we want to append the output to a existing file, then what should we do?

You use the `2>>` operator.
