TTYTYPE(5) Linux Programmer's Manual TTYTYPE(5)NAME
ttytype - terminal device to default terminal type mapping
DESCRIPTION
The /etc/ttytype file associates termcap/terminfo terminal type names with tty lines. Each line consists of a terminal type, followed by
whitespace, followed by a tty name (a device name without the /dev/) prefix.
This association is used by the program tset(1) to set the environment variable TERM to the default terminal name for the user's current
tty.
This facility was designed for a traditional time-sharing environment featuring character-cell terminals hardwired to a Unix minicomputer.
It is little used on modern workstation and personal Unixes.
FILES
/etc/ttytype
the tty definitions file.
EXAMPLE
A typical /etc/ttytype is:
con80x25 tty1
vt320 ttys0

tty - controlling terminal
DESCRIPTION
The file /dev/tty is a character file with major number 5 and minor number 0, usually of mode 0666 and owner.group root.tty. It is a syn-
onym for the controlling terminal of a process, if any.
In addition to the ioctl(2) requests supported by the device that tty refers to, the ioctl(2) request TIOCNOTTY is supported.
TIOCNOTTY
Detach the calling process from its controlling terminal.
If the process is the session leader, then SIGHUP and SIGCONT signals are sent to the foreground process group and all processes in the
current session lose their controlling tty.
This ioctl(2) call only works on file descriptors connected to /dev/tty. It is used by daemon processes when they are invoked by a user at
a terminal. The process attempts to open /dev/tty. If the open succeeds, it detaches itself from the terminal by using TIOCNOTTY, while
if the open fails, it is obviously not attached to a terminal and does not need to detach itself.
FILES

I am not sure if I am using the correct terminology but somehow my tty keeps changing on me. The man pages are confusing to me on what exactly the tty is. This is what I see when I run the tty command. Could anyone explain why my tty keeps changing?

Hello,

For example, I have a directory which contains all my... (3 Replies)
