How to do it...
tty means teletype. tty displays terminal-related information. Everything in Linux is a file. So, tty prints the filename of the terminal that is connected to standard input.
Now, open a terminal and run tty:
$ tty
After running this command, the current tty session will be displayed.
Open another terminal B and do the same; you will get that terminal’s tty session.
Now I have two tty sessions as:
- Terminal A = /dev/pts/4
- Terminal B = /dev/pts/7
In Terminal A, run the following command:
$ echo "Hello World" > /dev/pts/7
Now check Terminal B; Hello world will be displayed on the terminal. Again, run the following command to send another string to terminal B.
$ echo "Hello This is John" > /dev/pts/7
