如何在solaris下使用spawn和sftp捕获期望输出 [英] How to capture expect output using spawn and sftp under solaris

问题描述

我正在使用Expect生成一个sftp会话，如下所示:

I am using expect to spawn a sftp session as follows:

(为了清晰起见，大量的代码被剪掉了，是的，我理解其中的风险...)

(lots of code snipped for clarity, and yes I understand the risks...)

#!/opt/csw/bin/expect -f

<snip>

spawn sftp $user@$host 

set rez [connect $passw]
if { $rez == 0 } {
  send "cd $location\r"
  set timeout -1
  send "ls -l\r" 
  send "quit\r"
  expect eof
  exit 0
}
puts "\nError connecting to server: $host, user: $user and password: $passw!\n"
exit 1

这很好用.

我的具体问题是如何捕获文件中发送"ls -l \ r" 命令的结果.

My specific question is how to I capture the results of the send "ls -l\r" command in a file.

推荐答案

send "ls\r"之后，您应该expect一些东西.在expect语句之后，变量$expect_out(0,string)将包含所需的输出.您必须解析出实际的命令字符串和随后的提示..您将可以在 http://docs.activestate.com/activetcl/8.5/expect4win/

After you send "ls\r" you should expect something. After the expect statement, the variable $expect_out(0,string) will contain the output you want. You do have to parse out the actual command string and the subsequent prompt.. You'll be able to find some examples at http://docs.activestate.com/activetcl/8.5/expect4win/
