This directory contains scripts that give examples of using Pexpect.
|
|
|
|
hive.py
|
|
This script creates SSH connections to a list of hosts that
|
|
you provide. Then you are given a command line prompt. Each
|
|
shell command that you enter is sent to all the hosts. The
|
|
response from each host is collected and printed. For example,
|
|
you could connect to a dozen different machines and reboot
|
|
them all at once.
|
|
|
|
script.py
|
|
This implements a command similar to the classic BSD "script" command.
|
|
This will start a subshell and log all input and output to a file.
|
|
This demonstrates the interact() method of Pexpect.
|
|
|
|
fix_cvs_files.py
|
|
This is for cleaning up binary files improperly added to
|
|
CVS. This script scans the given path to find binary files;
|
|
checks with CVS to see if the sticky options are set to -kb;
|
|
finally if sticky options are not -kb then uses 'cvs admin'
|
|
to set the -kb option.
|
|
|
|
ftp.py
|
|
This demonstrates an FTP "bookmark".
|
|
This connects to an ftp site; does a few ftp commands; and then gives the user
|
|
interactive control over the session. In this case the "bookmark" is to a
|
|
directory on the OpenBSD ftp server. It puts you in the i386 packages
|
|
directory. You can easily modify this for other sites.
|
|
This demonstrates the interact() method of Pexpect.
|
|
|
|
monitor.py
|
|
This runs a sequence of system status commands on a remote host using SSH.
|
|
It runs a simple system checks such as uptime and free to monitor
|
|
the state of the remote host.
|
|
|
|
passmass.py
|
|
This will login to a list of hosts and change the password of the
|
|
given user. This demonstrates scripting logins; although, you could
|
|
more easily do this using the pxssh subclass of Pexpect.
|
|
See also the "hive.py" example script for a more general example
|
|
of scripting a collection of servers.
|
|
|
|
python.py
|
|
This starts the python interpreter and prints the greeting message backwards.
|
|
It then gives the user interactive control of Python. It's pretty useless!
|
|
|
|
rippy.py
|
|
This is a wizard for mencoder. It greatly simplifies the process of
|
|
ripping a DVD to mpeg4 format (XviD, DivX). It can transcode from any
|
|
video file to another. It has options for resampling the audio stream;
|
|
removing interlace artifacts, fitting to a target file size, etc.
|
|
There are lots of options, but the process is simple and easy to use.
|
|
|
|
sshls.py
|
|
This lists a directory on a remote machine.
|
|
|
|
ssh_tunnel.py
|
|
This starts an SSH tunnel to a remote machine. It monitors the connection
|
|
and restarts the tunnel if it goes down.
|
|
|
|
uptime.py
|
|
This will run the uptime command and parse the output into python variables.
|
|
This demonstrates using a single regular expression to match the output
|
|
of a command and capturing different variable in match groups.
|
|
The regular expression takes into account a wide variety of different
|
|
formats for uptime output.
|
|
|
|
df.py
|
|
This collects filesystem capacity info using the 'df' command.
|
|
Tuples of filesystem name and percentage are stored in a list.
|
|
A simple report is printed. Filesystems over 95% capacity are highlighted.
|
