Description:

Spawn class is used to invoke commands with which we need to interact. It provides methods for interacting with the spawned commands by using methods like send/expect. It is very similar in intent as Tcl/Expect’s spawn command.

class unicon.eal.backend.pty_backend.Spawn(spawn_command, *args, **kwargs)

Bases: Spawn

This class adds pty-specific spawn logic .

close()

is_alive()

Return whether this spawn has a usable PTY and live child.

The probe does not reap the child or invoke configured disconnect waits. Resource cleanup remains owned by close() and terminal I/O failure handling.

is_closed()

Return whether this PTY spawn cannot safely be used.
