TTY – TeleType

Read, heard and ever wondered what a tty is. Well it stands for teletype and it is a command used in the shell. Basically it gives information about the terminal that a user is currently at. TTY has historic significance as they were used in the first computers which were TeleType terminals and these were essentially remote controlled typewriters. When you enter the command ‘tty’ in the shell without the quotes you will receive a response ‘dev/pts/1’ or some other number which essentially tells you that you are using device /pts/1.
