A pseudo-TTY (pseudo terminal) is a software interface that emulates a physical terminal. It allows programs to interact with the terminal as if they were communicating with a real terminal device. Pseudo-TTYs are commonly used in Unix-like operating systems to provide terminal capabilities to applications that require user interaction.
Key features of pseudo-TTYs include:
Terminal Emulation: They simulate the behavior of a physical terminal, allowing applications to read from and write to the terminal.
Interactive Sessions: Pseudo-TTYs enable interactive sessions, such as when using SSH or running commands in a Docker container with the
-itflag.Input/Output Handling: They handle input and output streams, allowing for features like line editing, command history, and terminal control sequences.
Overall, pseudo-TTYs are essential for creating interactive command-line interfaces in various applications and environments.
