showconsole(8)
NAME
Showconsole - determines the underlying tty of stdin
Setconsole - sets the underlying tty of /dev/console
SYNOPSIS
showconsole 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.
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.
