Mac OSX 10.13.3 系統下親測沒問題，直接看代碼：

#!/bin/bash

lfname=tencentcloud_poc_ljl_0009
#這裏是任何bash 命令
ls

printf "\n";
printf "starting scp $lfname-1.0-2.app.zip....\n";
printf "\n";

#這裏開始利用 expect 執行scp 並實現自動輸入密碼
/usr/bin/expect<<EOF

set timeout -1

spawn scp ./apspackages/$lfname-1.0-2.app.zip root@10.X.X.X:/root/ljlapp

expect {
 
"*assword" {send "password\r";}
"yes/no" {send "yes\r"; exp_continue;}
}
expect eof

EOF

printf "done..\n"

Mac OSX bash命令執行自動 scp
