Linux expect 用法：
https://blog.csdn.net/catoop/article/details/48289991
运行脚本
root@Righteous:/tmp/tmp# vim expect_ftp_download.sh
root@Righteous:/tmp/tmp# which expect
/usr/bin/expect
root@Righteous:/tmp/tmp# vim expect_ftp_download.sh
root@Righteous:/tmp/tmp# cat expect_ftp_download.sh
#!/usr/bin/expect -f
set ip [lindex $argv 0 ]
set file [lindex $argv 1]
set timeout 10
spawn ftp $ip
expect "Name*"
send "test1\r"
expect "Password*"
send "test1\r"
expect "ftp>"
send "get $file\r"
expect {
"*bytes received*" { send_user "Download file success!\r";send "bye\r"}
"*File not found*" { send_user "Download file Failed!\r";send "bye\r"}
}
expect eof
注意expect脚本不能用bash来执行，chmod +x expect.sh，添加执行权限然后./expect.sh执行即可
