mussh 是shell开发的一个小工具，pssh是python开发的一个用来批量管理linux主机的工具，现在我们来介绍mussh和pssh的使用方法。
先说下mussh，mussh 是shell开发的一个小工具，刚学习运维和shell的朋友可以拿来锻炼下，做个工具的二次开发。

mussh的帮助，会看到他的帮助相当的简单。 代码如下
[root@devops-ruifengyun ~ ]$ mussh --help
Usage: mussh [OPTIONS] <-h host.. | -H hostfile> [-c cmd] [-C scriptfile]
mussh --help for full help text
Send a command or list of commands to multiple hosts.
OPTIONS:
--help This text.
-d [n] Verbose debug. Prints each action, all hosts
and commands to be executed to STDERR. 'n' can
be from 0 to 2.
-v [n] Ssh debug levels. Can be from 0 to 3.
-m [n] Run concurrently on 'n' hosts at a time (asynchronous).
Use '0' (zero) for infinite. (default if -m)
-q No output unless necessary.
-i <identity> [identity ..]
Load an identity file. May be used
more than once.
-o <ssh-args> Args to pass to ssh with -o option.
-a Force loading ssh-agent.
-A Do NOT load ssh-agent.
-b Print each hosts' output in a block without mingling
with other hosts' output.
-B Allow hosts' output to mingle. (default)
-u Unique. Eliminate duplicate hosts. (default)
-U Do NOT make host list unique.
-P Do NOT fall back to passwords on any host. This will
skip hosts where keys fail.
-l <login> Use 'login' when no other is specified with hostname.
-L <login> Force use of 'login' name on all hosts.
-s <shell> Path to shell on remote host. (Default: bash)

-c <command> Add a command or quoted list of commands and
args to list of commands to be executed on
each host. May be used more than once.
-C <file> [file ..]

executed on each host. May be used more
than once.
At least one host is required. Arguments are in no particular order.
