NAME


Showconsole - determines the underlying tty of stdin Setconsole - sets the underlying tty of /dev/console

SYNOPSIS


showconsole [-n]

setconsole /dev/tty<xy> < /dev/console

DESCRIPTION


showconsole determines the underlying character device of the current stdin. This can be used on /dev/console as current character device to get the real character device back.

setconsole sets the underlying tty of the system console /dev/console. This requires that the standard input is identical with /dev/console and exactly one argument, a valid character device is given. ."

OPTIONS


-n Return the major and minor device numbers instead of the device file name. This can be used to asked the kernel for the major and minor device numbers of a not existing device file in /dev. ."

BUGS


showconsole needs a mounted /proc file system and tries to set the controlling tty to stdin if no controlling tty is found. After reading /proc the status of the controlling tty is restored to avoid problems with getty processes.

FILES


/proc/<pid of showconsole>/stat
 the stat file of the showconsole process.
/dev/console
 the system console.
