Getting the process ID of the terminal in Unix/Linux
Hi,
How can we get the process id of the terminal we are using?
When we logged in to unix, we have an associated terminal. we can use "tty" command to get the terminal we are using like:
/dev/pts/0
I want to know the process id of this terminal. Please reply as I searched a lot but I didn't find any answer.
Thanks in advance!
Regards,

PTY(4) BSD Kernel Interfaces Manual PTY(4)
NAME
pty -- BSD-style compatibility pseudo-terminal driver
SYNOPSIS
device pty
DESCRIPTION
The pty driver provides support for the traditional BSD naming scheme that was used for accessing pseudo-terminals. When the device
/dev/ptyXX is being opened, a new terminal shall be created with the pts(4) driver. A device node for this terminal shall be created, which
has the name /dev/ttyXX.
New code should not try to allocate pseudo-terminals using this interface. It is only provided for compatibility with older C libraries that
tried to open such devices when posix_openpt(2) was being called.
FILES
The BSD-style compatibility pseudo-terminal driver uses the following device names:
/dev/pty[l-sL-S][0-9a-v] Pseudo-terminal master devices.
/dev/tty[l-sL-S][0-9a-v] Pseudo-terminal slave devices.
DIAGNOSTICS
None.
SEE ALSO
posix_openpt(2), pts(4), tty(4)
HISTORY
A pseudo-terminal driver appeared in 4.2BSD.
BUGS
Unlike previous implementations, the master slave device nodes are destroyed when the PTY becomes unused. A call to stat(2) on a nonexistent
master device will already cause a new master device node to be created. The master device can only be destroyed by opening and closing it.
The pty driver cannot be unloaded, because it cannot determine if it is being used.
