Good script to watch temprorary files through and deciede whether you want to delete file or not.

play.sh

#!/bin/bash

play() {
  mplayer -fs $1
}

callback() {
  local data=$1
  rm -v "./$data"
}

main() {
  local ext=$1
  for x in *$ext; do 
    play $x
    read -p "Are you sure? " -n 1 choice 
    echo
    if [[ $choice =~ ^[Yy]$ ]]; then
      callback $x
    fi
  done

}


# init()

if [$# -le 1]; then
  echo "No extension supplied, falling back to .flv"
  main 'flv'
else
  main $1
fi
