It should work in every Korn shell derivative, including ksh, pdksh, ash, bash, and zsh. It is a requirement of the POSIX shell (see http://www.opengroup.org/onlinepubs/009695399/utilities/exec.html). It also works in the Heirloom Bourne shell (http://heirloom.sourceforge.net/sh.html), and was at least documented as doing this in the 1979 7th Edition Bourne shell (the original Bourne shell), so I guess it is safe to assume that this works pretty much everywhere! > > AFAIK, yes.
