Then you are given a command line prompt. Each 22 shell command that you enter is sent to all the hosts. The 23 response from each host is collected and printed. For example, 24 you could connect to a dozen different machines and reboot 25 them all at once. 26 </p></blockquote> 27 28 <p><span class="code">script.py</span></p> 29 <p><blockquote> 30 This implements a command similar to the classic BSD 31 "script" command. 32 This will start a subshell and log all input and 33 output to a file. 34 This demonstrates the interact() method of Pexpect. 35 </p></blockquote> 36 37 <p><span class="code">fix_cvs_files.py</span></p> 38 <p><blockquote> 39 This is for cleaning up binary files improperly 40 added to CVS. 41 This script scans the given path to find binary 42 files; 43 checks with CVS to see if the sticky options are set 44 to -kb; 45 finally if sticky options are not -kb then uses 'cvs 46 admin' to 47 set the -kb option. 48 </p></blockquote> 49 50 <p><span class="code">ftp.py</span></p> 51 <p><blockquote> 52 This demonstrates an FTP "bookmark". 53 This connects to an ftp site; does a few ftp stuff; 54 and then gives the user 55 interactive control over the session. In this case 56 the "bookmark" is to a 57 directory on the OpenBSD ftp server. It puts you in 58 the i386 packages 59 directory. You can easily modify this for other 60 sites. 61 This demonstrates the interact() method of Pexpect. 62 </p></blockquote> 63 64 <p><span class="code">monitor.py</span></p> 65 <p><blockquote> 66 This runs a sequence of commands on a remote host 67 using SSH. 68 It runs a simple system checks such as uptime and 69 free to monitor 70 the state of the remote host. 71 </p></blockquote> 72 73 <p><span class="code">passmass.py</span></p> 74 <p><blockquote> 75 This will login to each given server and change the 76 password of the 77 given user. This demonstrates scripting logins and 78 passwords. 79 </p></blockquote> 80 81 <p><span class="code">python.py</span></p> 82 <p><blockquote> 83 This starts the python interpreter and prints the 84 greeting message backwards. 85 It then gives the user iteractive control of Python. 86 It's pretty useless! 87 </p></blockquote> 88 89 <p><span class="code">rippy.py</span></p> 90 <p><blockquote> 91 This is a wizard for mencoder. It greatly simplifies 92 the process of 93 ripping a DVD to Divx (mpeg4) format. It can 94 transcode from any 95 video file to another. It has options for resampling 96 the audio stream; 97 removing interlace artifacts, fitting to a target 98 file size, etc. 99 There are lots of options, but the process is simple 100 and easy to use. 101 </p></blockquote> 102 103 <p><span class="code">sshls.py</span></p> 104 <p><blockquote> 105 This lists a directory on a remote machine. 106 </p></blockquote> 107 <p><span class="code">ssh_tunnel.py</span></p> 108 <p><blockquote> 109 This starts an SSH tunnel to a remote machine. It 110 monitors the connection 111 and restarts the tunnel if it goes down. 112 </p></blockquote> 113 <p><span class="code">uptime.py</span></p> 114 <p><blockquote> 115 This will run the uptime command and parse the 116 output into variables. 117 This demonstrates using a single regular expression 118 to match the output 119 of a command and capturing different variable in 120 match groups. 121 The grouping regular expression handles a wide variety of different 122 uptime formats. 123 </blockquote> 124 125 <p> 126 <a href="http://sourceforge.net/projects/pexpect/" 127 title="The Pexpect project page on SourceForge.net"> <img 128 src="http://sourceforge.net/sflogo.php?group_id=59762&type=5" 129 alt="The Pexpect project page on SourceForge.net" border="0" 130 height="31" width="105"> </a> 131 </p> 132 </div> 133 134 </body> 135 </html> 136
