2014年第一个脚本，哈哈！！！ expect实现远程主机自动执行命令脚本： 

#!/usr/bin/expect --if { [llength $argv] < 4 } {	puts "Usage: $argv0 ip user passwd port commands timeout"	exit 1}match_max 600000set ip [lindex $argv 0]set user [lindex $argv 1]set passwd [lindex $argv 2]set port [lindex $argv 3]set commands [lindex $argv 4]set timeoutflag [lindex $argv 5]set yesnoflag 0set timeout $timeoutflagfor {} {1} {} {# for is only used to retry when "Interrupted system call" occuredspawn /usr/bin/ssh -q -l$user -p$port $ipexpect 	{	"assword:" {		send "$passwd\r"		break;	}	"yes/no)?" {		set yesnoflag 1		send "yes\r"		break;	}	"FATAL" {		puts "\nCONNECTERROR: $ip occur FATAL ERROR!!!\n"		exit 1	}	timeout {		puts "\nCONNECTERROR: $ip Logon timeout!!!\n"		exit 1	}	"No route to host" {		puts "\nCONNECTERROR: $ip No route to host!!!\n"		exit 1	}	"Connection Refused" {		puts "\nCONNECTERROR: $ip Connection Refused!!!\n"		exit 1	}	"Connection refused" {		puts "\nCONNECTERROR: $ip Connection Refused!!!\n"		exit 1	}	"Host key verification failed" {		puts "\nCONNECTERROR: $ip Host key verification failed!!!\n"		exit 1	}	"Illegal host key" {		puts "\nCONNECTERROR: $ip Illegal host key!!!\n"		exit 1	}			"Connection Timed Out" {		puts "\nCONNECTERROR: $ip Logon timeout!!!\n"		exit 1	}	"Interrupted system call" {		puts "\n$ip Interrupted system call!!!\n"	}}}if { $yesnoflag == 1 } {	expect {		"assword:" {			send "$passwd\r"		}		"yes/no)?" {			set yesnoflag 2			send "yes\r"		}	}}if { $yesnoflag == 2 } {	expect {		"assword:" {			send "$passwd\r"		}	}}expect {	"]" {send "$commands \r"}	"assword:" {		send "$passwd\r"		puts "\nPASSWORDERROR: $ip Password error!!!\n"		exit 1	}}expect {	"]" {send "sleep 1 \r"}}expect {	"]" {send "exit\r"}}expect eof {	puts "OK_SSH: $ip\n"	exit 0;}

用法：

./ssh.expUsage: ./ssh.exp ip user passwd port commands timeout
