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 $ip

expect  {

        "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

                exit 1
        }

        }}}if { $yesnoflag == 1 } {
        expect {
                "assword:" {
                        send "$passwd\r"
                }

                "yes/no)?" {
                        set yesnoflag 2
                        send "yes\r"
                }
        }}if { $yesnoflag == 2 } {
        expect {

        "#" {send "$commands \r"}
        ">" {send "$commands \r"}
        "$" {send "$commands \r"}
        "assword:" {
                send "$passwd\r"

        "$" {send "sleep 1 \r"}}expect {

        ">" {send "exit\r"}
        "$" {send "exit\r"}}expect eof {
        puts "OK_SSH: $ip\n"
        exit 0;}
