Eunice was a Unix-like working environment for VAX computers running DEC's VAX/VMS, based on the BSD version of Unix. It was originally developed ca. 1981 by David Kashtan at SRI,[1] and later maintained and marketed by The Wollongong Group.[2]

Eunice was one of several Unix compatibility packages developed during the 1980s. It provided VMS binary versions of Unix tools, a VMS object library emulating the Unix API (including the system call interface) and an assembler that produced VMS binaries.[3] Eunice was criticized for its performance problems and not quite complete Unix compatibility.[1] Eunice's reputation for poor compatibility inspired the "Congratulations. You aren't running Eunice." message included in the Perl configure script.[4][5]
