I've never heard about builtin sleep. It's just not GNU sleep (BSD on Mac, or something else). The variant with perl is the best solution (on modern enough boxes).

ksh93 does indeed have a built-in sleep.

GNU sleep is not special in this regard. I regularly use *BSD and every BSD's sleep(1) supports fractions of a second.

Oh, yes. I checked it in ksh with "which" but I should do it with "type". Too many shells, too many *nixes, too little experience... )))
