SCO UnixWare Binaries I do not recommend that you use a pre-compiled lsof binary. It is better that you compile lsof for yourself from the distributed sources. Caldera|SCO UnixWare binaries are stored in subdirectories named after the relevant version of UnixWare. Within those subdirectories are further ones that identify the type of architecture on which the binary was generated: x86at for Intel-based bit systems. Vic Abell February 17, 2004 .
