Linux expect

一个expect使用的例子程序
[root@dba-server01 tftpboot]# less expect-ssh.exp

//提示用法proc usage {} {    puts stderr "usage: $::argv0 username password hostip"    exit 1}proc connect {pass} {   expect {       "(yes/no)?" {           send "yes\n"           expect "*password:" {                send "$pass\n"                expect {                    "*#" {                        return 0                    }                }           }       }       "*password:" {           send "$pass\n"           expect {               "*#" {                   return 0               }           }       }   }   return 1}if {$argc != 3} { usage }set username [lindex $argv 0]set password [lindex $argv 1]set hostip [lindex $argv 2]spawn ssh ${username}@${hostip}//这里表示如果连接不成功则返回!if {![connect $password]} {    exit 1}send "touch /home/oracle/test.txt\n"//注意转移回车的使用,以免和exit指令连在一起.这里是目标机要执行的指令.send "exit\n"expect eof
