'''Pexpect is a Python module for spawning child applications and controlling
|
||
|
|
them automatically. Pexpect can be used for automating interactive applications
|
||
|
|
such as ssh, ftp, passwd, telnet, etc. It can be used to a automate setup
|
||
|
|
scripts for duplicating software package installations on different servers. It
|
||
|
|
can be used for automated software testing. Pexpect is in the spirit of Don
|
||
|
|
Libes' Expect, but Pexpect is pure Python. Other Expect-like modules for Python
|
||
|
|
require TCL and Expect or require C extensions to be compiled. Pexpect does not
|
||
|
|
use C, Expect, or TCL extensions. It should work on any platform that supports
|
||
|
|
the standard Python pty module. The Pexpect interface focuses on ease of use so
|
||
|
|
that simple tasks are easy.
|
||
|
|
|
||
|
|
There are two main interfaces to the Pexpect system; these are the function,
|
||
|
|
run() and the class, spawn. The spawn class is more powerful. The run()
|
||
|
|
function is simpler than spawn, and is good for quickly calling program. When
|
||
|
|
you call the run() function it executes a given program and then returns the
|
||
|
|
output. This is a handy replacement for os.system().
|
||
|
|
|
||
|
|
For example::
|
||
|
|
|
||
|
|
pexpect.run('ls -la')
|
||
|
|
|
||
|
|
The spawn class is the more powerful interface to the Pexpect system. You can
|
||
|
|
use this to spawn a child program then interact with it by sending input and
|
||
|
|
expecting responses (waiting for patterns in the child's output).
|
||
|
|
|
||
|
|
For example::
|
||
|
|
|
||
|
|
child = pexpect.spawn('scp foo user@example.com:.')
|
||
|
|
child.expect('Password:')
|
||
|
|
child.sendline(mypassword)
|
||
|
|
|
||
|
|
This works even for commands that ask for passwords or other input outside of
|
||
|
|
the normal stdio streams. For example, ssh reads input directly from the TTY
|
||
|
|
device which bypasses stdin.
