VHANGUP(8) The SuSE boot concept VHANGUP(8)NAME
Vhangup - Cause a virtually hangup on the specified terminals
SYNOPSIS
vhangup [/dev/<terminal> [/dev/<terminal>]]
DESCRIPTION
vhangup simulates a hangup on the specified terminals. Not existing device files or devices will be ignored.
EXAMPLES
vhangup /dev/tty1 /dev/tty2 /dev/tty3 /dev/tty4 /dev/tty5 /dev/tty6 /dev/ttyS1
This will replace all open file descriptors in the kernel that points to the listed ttys by a dummy that will deny further reading/writing
to the device. It also send the signals SIGHUP/SIGCONT to the processes which have file descriptors open on the listed ttys.
RETURN VALUE
On success, zero is returned. On error, 1 is returned.

SHOWCONSOLE(8) The SuSE boot concept SHOWCONSOLE(8)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/con-
sole 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.

Why do shell builtins like echo and pwd have binaries in /bin? When I do which pwd, I get the one in /bin. that means that I am not using the builtin version? What determines which one gets used? Is the which command a definitive way to determine what is being run when I enter pwd? (16 Replies)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)

Hi all,
I am learning POSIX shell programming, and the book I read, uses the let command for integer arithmetic.

Hi all, (mainly Neo)...
I keep noticing that the SQRT code I wrote recently for a POSIX shell keeps appearing, (the green colour sticks out like a sore thumb).
