### APT Tips (tested only on Ubuntu)

# How to just buffer each line (rather than the entire input stream) when using awk / gawk to read data from a pipe.
  awk '{ print $0 ; system("") }' # compatible with POSIX complient systems
  gawk '{ print $0 ; system("") }' # gawk is smart and will not actually start a sub-shell

  # fflush - is going to offer something similar (although you can speicify which kind of output you would like to flush).
