Interactive and Non-Interactive Modes
Two other methods for accessing the zone and for executing commands inside the
zone are also provided by the zlogin command. These methods are interactive mode
and non-interactive mode.
In interactive mode, a new pseudo-terminal is allocated for use inside the zone.
Unlike console mode, in which exclusive access to the console device is granted,
an arbitrary number of zlogin sessions can be open at any time in
interactive mode. Interactive mode is activated when you do not include a command
to be issued. Programs that require a terminal device, such as an editor,
operate correctly in this mode.
Non-interactive mode is used to run shell-scripts which administer the zone. Non-interactive mode
does not allocate a new pseudo-terminal. Non-interactive mode is enabled when you supply
a command to be run inside the zone.
