NOS/VE (Network Operating System / Virtual Environment) was an operating system with time-sharing capabilities, written by Control Data Corporation in the 1980s. It is a virtual memory operating system, employing the 64-bit virtual mode of the CDC Cyber 180 series computers. NOS/VE replaced the earlier NOS operating system of the 1970s.
Commands
All NOS/VE commands have the form verb{_adjective}_noun. These commands are abbreviated with the first three characters of verb followed by the first character(s) of all further words.
Full command | Abbreviation | UNIX command |
---|---|---|
display_catalog | disc | ls |
display_working_catalog | diswc | pwd |
change_working_catalog | chawc | cd |
delete_catalog | delc | rmdir |
copy_file | copf | cp |
delete_file | delf | rm |
create_connection | crec | telnet |
Inspired by addressing structure-members in various programming languages, the catalog separator is the dot.
Subsystems like FTP integrate into the command shell. They change the prompt and add commands like get_file. Thereby statements like flow-control stay the same and subsystems can be mixed in procedures (scripts).
Parameters
Commands could take parameters such as the create_connection command:
crec telnet sd='10.1.2.3'
would connect you to IP address 10.1.2.3 with telnet service.
