Expect

Question

我为 sftp 写了一个脚本。它可以正常工作几秒钟。但几秒钟后退出。我尝试了很多方法，但无法找出问题所在。这是我的代码。

#!/usr/bin/expect

set now [clock seconds]
set now [expr {$now - 3600}]
set date [clock format $now -format {%Y%m%d%H}]

set SOURCE "/home/sms/SMSC-Sec-2.0.7.0_MT/cdrs/"
spawn sftp root@10.167.250.75
  expect "password:"
     send "teledna\r"
     sleep 1
     expect "sftp>"
        send "cd /home/sms/CDRS-Noida \r"
        expect "sftp>"
           send "pwd \r"
           expect "sftp>"
               send "mput $SOURCE/DNA-AegisGw-CDR_PREPAID_$date*.log  \r"
               expect -exact "sftp>"
               send "quit \r"
send "I am here"

输出：

spawn sftp root@10.167.xx.xx
root@10.167.xx.xx's password:
Connected to 10.167.xx.xx.
sftp> cd /home/sms/CDRS-Noida
sftp> pwd

几秒后退出，这样说 5

由于您mput正在处理许多文件，因此预计需要相当长的时间。因此，请尝试在 mput:

之后使用更长的 timeout（默认值：10）

send "mput $SOURCE/DNA-AegisGw-CDR_PREPAID_$date*.log \r" 
expect -timeout 600 -exact "sftp>"

或者您也可以设置全局 timeout:

set timeout 600
spawn ...

并且无限 timeout 可以由值 −1 指定。

Expect - Spawn 在一段时间后退出

Expect - Spawn exiting after sometime
