UNIX for OpenVMS Users, 3E, makes it easy to see what OpenVMS and UNIX have in common, and to transfer your knowledge and experience in OpenVMS over to the world of UNIX. Since most shops rely on more than one operating system, it is critical for system administrators and managers to understand the similarities and differences between platforms, so they can easily work in both environments while taking full advantage of the tools and applications available on each. This book offers OpenVMS professionals a concise source of information, so that they can quickly bring their expertise to bear on UNIX file management, e-mail, networking, and security. This new edition of the book is enhanced with updated references to VMS, incorporates suggestions made by readers of previous editions, and particularly, recognizes other UNIX implementations in addition to HP's Tru64.
