|
|||
|
|
operation on a timesharing system, such as read or write any file on the
|
|||
|
|
system regardless of protections, change or look at any address in the
|
|||
|
|
running monitor, crash or reload the system, and kill or create jobs and
|
|||
|
|
user accounts. The term was invented on the TENEX operating system, and
|
|||
|
|
carried over to TOPS-20, XEROX-IFS, and others. The state of being in a
|
|||
|
|
privileged logon is sometimes called <span class="firstterm">wheel
|
|||
|
|
mode</span>. This term entered the Unix culture from TWENEX in the
|
|||
|
|
mid-1980s and has been gaining popularity there (esp. at university
|
|||
|
|
sites).
