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¶

-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.
