这个expect脚本是为了获取线上服务器的容量大小，并无实际意义

#!/usr/bin/expect

set timeout 60       #设置超时

set user [lindex $argv 0]    #设置第一个参数

set password [lindex $argv 1]

set ipaddr [lindex $argv 2]
set port [lindex $argv 3]

set mypassword [lindex $argv 4]

spawn ssh $user@$ipaddr -p $port    #远程连接ssh
expect {
    "(yes/no)" { send "yes\r"; exp_continue }
    "password:" { send "$password\r" }
}

expect $user@*  {send " df -h > $ipaddr.disk.rocky \r" }  ;
expect $user@*  {send " df -ih >> $ipaddr.disk.rocky \r"}


#expect $user@*  {send " scp -P 8026 *.rocky rockycai@180.173.150.12:/home/rockycai/ip_file/$ipaddr/ \r" }  ;
#expect {
#    "(yes/no)" { send "yes\r"; exp_continue }
#    "password:" { send "$mypassword\r" }
#}

expect $user@*  {send " rm -rf *.rocky \r"}
expect $user@*  {send " exit \r" } ;

#spawn /home/rockycai/ssh/autoDemo.sh $ipaddr

expect eof ;

可以根据实际情况来更改需求
