Class Public methods

Spawns the specified command on a newly allocated pty. You can also use the alias ::getpty.

The command's controlling tty is set to the slave device of the pty and its standard input/output/error is redirected to the slave device.

command and command_line are the full commands to run, given a String. Any additional arguments will be passed to the command.

Return values

In the non-block form this returns an array of size three, [r, w, pid].

In the block form these same values will be yielded to the block:

r

A readable IO that that contains the command's standard output and standard error

w

A writable IO that is the command's standard input

pid

The process identifier for the command.
