If I do something like
`cat myfile | myreader`

cat will send the *myfile* contents line by line, as fast as possible to standard output.

**I'd like to send the file contents line by line, but "sleep" some time after every line.**

Does any of you know how this can be done?

I know it's possible to wait in *myreader* but this is not the question. It's not always possible to modify the program reading standard input or it is not desirable in my case.
