Who are all logged out
I have a situation where I have to capture information of all users who log out, along with the terminal info(tty command).
For example, I may have logged in with /dev/pts/2 as well as /dev/pts4.
Now, when I log out of the session with /dev/pts/2, I need that to be sent in an email to a particular email id. Similarly, when the same user id, logs out of /dev/pts/4 also, a similar email needs to be sent, instead of just sending "User id ... has logged out". This way, all the multiple sessions of a user id can be tracked.
Can anyone help me with a script for this?

PTS(4) Linux Programmer's Manual PTS(4)
NAME
ptmx, pts - pseudo-terminal master and slave
DESCRIPTION
The file /dev/ptmx is a character file with major number 5 and minor number 2, usually of mode 0666 and owner.group of root.root. It is
used to create a pseudo-terminal master and slave pair.
When a process opens /dev/ptmx, it gets a file descriptor for a pseudo-terminal master (PTM), and a pseudo-terminal slave (PTS) device is
created in the /dev/pts directory. Each file descriptor obtained by opening /dev/ptmx is an independent PTM with its own associated PTS,
whose path can be found by passing the descriptor to ptsname(3).
Before opening the pseudo-terminal slave, you must pass the master's file descriptor to grantpt(3) and unlockpt(3).
Once both the pseudo-terminal master and slave are open, the slave provides processes with an interface that is identical to that of a real
terminal.
Data written to the slave is presented on the master descriptor as input. Data written to the master is presented to the slave as input.
In practice, pseudo-terminals are used for implementing terminal emulators such as xterm(1), in which data read from the pseudo-terminal
master is interpreted by the application in the same way a real terminal would interpret the data, and for implementing remote-login pro-
grams such as sshd(8), in which data read from the pseudo-terminal master is sent across the network to a client program that is connected
to a terminal or terminal emulator.
Pseudo-terminals can also be used to send input to programs that normally refuse to read input from pipes (such as su(1), and passwd(1)).
FILES
/dev/ptmx, /dev/pts/*
NOTES
The Linux support for the above (known as Unix98 pty naming) is done using the devpts file system, that should be mounted on /dev/pts.
Before this Unix98 scheme, master ptys were called /dev/ptyp0, ... and slave ptys /dev/ttyp0, ... and one needed lots of preallocated
device nodes.
