Any entry in a pipe could be buffering. In a quick test here, awk is buffering. To find the buffering, try using the pieces up to a given stage with " | cat " added at the end. If this buffers, you've found the problem. Unbuffered output is usually slower, so it is normally done only to a terminal. I think the only easy way to externally disable the buffer is to wrap the program in a pseudo-tty. Alternatively, look for an option that lets you explicitly unbuffer. (for instance, in perl, do: $| = 1; )
