wheel bit
|
|
|
|
n. A privilege bit that allows the possessor to perform some restricted
|
|
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 wheel mode. This term entered the Unix
|
|
culture from TWENEX in the mid-1980s and has been gaining popularity there
|
|
(esp. at university sites). See also root.
