UNIX-VM-VMS Cross-Reference

  O. Barring PPE/DEE and D. M. Edsall CN/PDP (DELPHI Collaboration)

The DELPHI collaboration and other users at CERN are being asked to migrate their computing needs from CERNVM to a Unix-based working environment over the course of the next two years. As an aid to our users, we created a Unix manual for beginning users who had never worked in Unix before. In it we included a comparison of commands used in the Unix, VMS and VM/CMS operating systems. We felt it would be helpful to share this comparison with other CERN users as an aid in their eventual migration. Please note that some of these commands apply specifically to the CORE environment and are not standard Unix commands.

If you are just beginning to learn Unix but you have been working in either a VM/CMS or VMS environment for some time, here is a table showing commands for each operating system which perform the same functions. Not all commands are represented, just those which are most useful. Certain commands exist in some operating systems and not in others (for example, there is no concept of a directory in VM/CMS). Also, there are some commands which, in Unix, are shell dependent. They are flagged below as and you are referred to the Unix manual pages for /bin/sh, /bin/csh, /bin/tcsh and /bin/ksh for more information. As DELPHI has chosen the C shell as the default shell, the answers are listed for the C shell.
