功能类似于multissh。事实上我也抄了这个名字//grin。
要求安装了 pexpect 这个包先。
用法见usage:
Usage: ./multissh.py -f cmdfile -l username -c cmd -n nodesfile -v -r
execut cmd on remote hosts (all hosts in ./hosts.txt by default)
-v verbose
-r recording hosts on which mission succeeded and failed
-l username
-c cmd to be executed remotely
-n file containing the nodes
-f file conaining the cmd
-h show the usage
就是指定一个文件比如nodes.txt以及命令以后,它可以自动
登录 到nodes.txt包含的节点里执行命令。可以在源文件里替换进你自己的密码,也可以使用公钥密钥
登录 不需输入密码。指定了v选项的话得到在远端每台主机上的详细输出。指定了r选项的话记录下那些节点成功那些节点失败。
我前面的帖子里有关于ansi_color的一个脚本,拿过来可以配合使用得到彩色输出
1. #!/usr/bin/python

另附一个邮件列表组的讨论内容:
python-cn邮件列表 写道
python 能不能模拟键盘输入字符,类似于TCL的post,比如在我用SSH 连接到LINUX,然后用PYTHON 来输入ls命令。急用

你这个并非模拟键盘输入,
而仅仅是远程通过 ssh 执行命令,
