Description

You can change the current console device using the swcons command. You can change the device to be the system console on the next start of the system using the chcons command.

Flags

-a	Displays a list of attribute name = attribute value pairs for the console device and console logging and tagging attributes. When used with the -b flag, the values are retrieved from the ODM. Without the -b flag, the values are retrieved from the console device driver. For additional information about console output logging and tagging, see the console Special File in the AIX 5L Version 5.2 Files Reference book. Note This flag is not valid with the -O flag or the -d flag.
-b	Displays the full path name of the system console selected for the next startup of the system.
-d	Displays the full path name of the system console selected on the current startup of the system. Note This flag is not valid with the -O flag or the -a flag.
-O	Similar to the -a flag but outputs the attribute names and values in a format suitable for use by SMIT. This flag is NOT valid with the -d flag. Note This flag is not valid with the -d flag or the -a flag.
-s	Suppresses reporting of the path name.
