SHOWCONSOLE(8) The SUSE boot concept SHOWCONSOLE(8)

NAME

Showconsole - determines the real tty of stdin
Setconsole - redirect system console output to a tty

SYNOPSIS

showconsole [-n]

setconsole [-r|/dev/tty<xy>]

DESCRIPTION

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

With an terminal device as argument setconsole redirects the output that would have gone to /dev/console or /dev/tty0 to the given terminal. Without any argument or the option the setconsole undo any redirection.

OPTIONS

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.
