Really?

Please tell me the output of this script:

  #!/bin/zsh

  zmodload zsh/zpty

  export ZDOTDIR=/tmp/zsh
  export HISTFILE=$ZDOTDIR/.history
  export HISTSIZE=2
  export SAVEHIST=10

  mkdir -p $ZDOTDIR
  touch $ZDOTDIR/.zshrc

  for n in $(seq 10); do
  zpty $n zsh

  zpty -w $n <<-EOF
  echo one
  echo two
  exit
  EOF

  zpty -r $n _
  done

  wc -l $HISTFILE

I wonder if you will keep your derogatory tone towards me after running it.
