set passwd "XXXXXXXX"

spawn ssh hadoop@$host

expect {

"yes/no" { send "yes\r"; exp_continue}

"password:" { send "$passwd\r" }

}

expect "$"

send "hostname \r"

#send "touch /tmp/expect_new.txt\r"

#send "sudo mkdir -p /home/backup/export \r"

send "sudo chown -R hadoop.hadoop /home/backup/export && chmod 755 /home/backup/export \r"

send "exit\r"

以上儲存為檔名：expect_test.exp， 並賦執行許可權 chmod +x  expect_test.exp

說明:

set timeout 1 設定登入時間 1秒

set host [lindex $argv 0]  設定輸入第一個引數為host變數的值，即：主機名稱
