shell腳本模擬交互操作實現上傳文件至sftp

需求：

將/home/log/下的所有.txt后綴的文件上傳至sftp服務器中

方法：

#!/bin/bash

logdir="/home/log/"
sftpremote='172.29.251.11'
sftp_user='collection_log'
stp_port='22'
sftp_password='hello23+'

cd $logdir

/usr/bin/expect << EOF
set timeout 20
spawn sftp -P $stp_port ${sftp_user}@${sftpremote}
expect  { 
    "yes/no" { 
        send "yes\r" 
        exp_continue 
            }         
            "assword:" { 
            send "$sftp_password\r" 
            }
        }

expect "sftp> "
send "cd log\r"
expect "sftp> "
send "put *.txt\r"
expect "sftp> "
send "bye"
EOF
