write code to display "Hello terminal." On the terminal device with a name /dev/pts/1.

Solutions

Expert Solution

/dev/pts is a pseudo-terminal. Terminals are of two types:
1. hardware terminal or tty
2. pseudo terminal or pty

Hardware terminals are actual terminals connected physically to the serial port.

  • pseudo terminals can be applications such as xterm, konsole, etc
  • they can be multiplexer applications such as tmux, screen, etc
  • they can also be remote applications such as telnetd, etc.

When using such an application, the terminal the data is routed to a pseudoterminal. It is named as /deve/pts
1 denotes the terminal number.

The following is a valid code to display "hello terminal" on /dev/pts/1

First connect to a pseudo terminal such as xterm, telnetd, etc then run the following code:

echo Hello terminal > /dev/pts/1
