我需要制定一种从远程服务器获取FTP文件的方法。我无法使用键，因此登录名必须是“交互式的”。我觉得期望是要走的路。
我在bash脚本中具有以下期望代码：
expect <<EOD
spawn sftp $sftp_user@$sftp_svr
expect "password:"
send "$sftp_pw\r"
expect "sftp> "
send "mget $getfile_path$getfile_name $savefile_path\r"
expect "sftp> "
send "bye\r"
EOD
该代码段仅检索一个文件时效果很好。但是，如果需要检索多个文件，则永远不会执行最终的“ expect sftp>”。工作：
[ed@svr1 ~]$ ./sftp_expect.sh
spawn sftp user@svr2
user@svr2's password:
Connected to svr2.
sftp> mget /data/user/upload/lastcheck1.txt /home/ed/report_received/
Fetching /data/user/upload/lastcheck1.txt to /home/ed/report_received/lastcheck1.txt
/data/user/upload/lastcheck1.txt 100% 56 26.9KB/s 00:00
sftp>
[ed@svr1 ~]$
不工作：
[ed@svr1 ~]$ ./sftp_expect.sh
spawn sftp user@svr2
user@svr2's password:
Connected to svr2.
sftp> mget /data/user/upload/lastcheck*.txt /home/ed/report_received/
Fetching /data/user/upload/lastcheck1.txt to /home/ed/report_received/lastcheck1.txt
/data/user/upload/lastcheck1.txt 100% 56 26.5KB/s 00:00
Fetching /data/user/upload/lastcheck2.txt to /home/ed/report_received/lastcheck2.txt
/data/hf_user/upload/lastcheck2.txt 100% 56 19.3KB/s 00:00
Fetching /data/user/upload/lastcheck_svr2.txt to /home/ed/report_received/lastcheck_svr2.txt
/data/user/upload/lastcheck_svr2.txt 100% 56 31.9KB/s 00:00
sftp>
^C
[ed@svr1 ~]$
脚本获取文件，期望得到“期望的东西”，但不会继续：
