ofcourse many problems lying around

  • no arguments to cp
  • cp is hardcoded
  • although it calculates total size to copy, multiple arguments may fail
  • if cat fails we get an infinite loop
  • etc

oeople should use stuff like pv, this was hacked for fun,
and if used it's better of with only one soure and target file.
