Es shell

The es shell is a Unix shell that uses the a scripting language similar to the rc shell. The goal of the es shell is to provide a fully functional programming language as a Unix shell. The bulk of es' development occurred in the early 1990s.

Es, unlike other modern shells, does not have job control. Patches to provide job control have been offered, but the currently available job control patches for es have memory leak problems.
