Frequently asked questions

What does TTY stand for?

It stands for teletypewriter. The original machines were electromechanical typewriters that sent and received text down a wire, and the name stuck for the software terminals that replaced them.

What is the difference between TTY and PTY?

A TTY is the general idea of a terminal device, historically a real piece of hardware. A PTY, or pseudo-terminal, is a software emulation of one, which is what you are using whenever you open a terminal window or connect over SSH.

Why do scripts complain about 'no TTY'?

Some commands need an interactive terminal, for example to hide a password as you type it. When they run from a cron job, a pipeline or a container without a terminal attached, there is no TTY and the command refuses or fails.
