节省ls命令的结果，在本地机器上远程SFTP服务器 [英] save the result of ls command in the remote sftp server on local machine

问题描述

我见过<一个href=\"http://stackoverflow.com/questions/14150451/how-do-i-pipe-the-output-of-an-ls-on-remote-server-to-the-local-filesystem-via-s\">This问题但我不太满意的答案。我连接到远程SFTP服务器，我会尽LS那里，我想有我的本地机器上LS的结果。我不希望任何额外的东西要保存，ls命令仅结果。我可以将结果保存到一个变量访问本地计算机上？

 ＃！的/ usr / bin中/预期产卵SFTP [e-mail]
预计密码
发送输入mypassword \\ N的;
期望SFTP＆gt;中
发送LS \\ n//保存在这里
相互作用
 

解决方案

下面是我会怎么做，有更多的传统的方法，需要打开一个文件写入所需的输出（我喜欢@kastelian的LOG_FILE理念，虽然）：

 ＃！的/ usr / bin中/预期产卵SFTP [e-mail]
预计密码
发送输入mypassword \\ N的;
期望SFTP＆gt;中设置文件[开放的/ tmp / LS-输出W];＃打开进行写入并设置文件标识符期望*;＃匹配缓冲任何以便清除它发送LS \\ R预计{
    SFTP＆gt;中{
        把$文件$ expect_out（缓冲）;＃保存到文件，因为最后一场比赛（清）缓冲区内容，直到这场比赛（SFTP＆GT;提示）
    }
    超时{;＃几分优雅的方式，如果出现错误死
        把$文件错误：期待块超时
    }
}关闭$文件相互作用
 

生成的文件将持有相同的两个额外的行作为LOG_FILE提出的解决方案：ls命令在顶部和底部的SFTP>提示符下，但你应该可以，只要你喜欢处理那些<。 / p>

我测试了这一点，它的工作原理。

让我知道，如果它帮助！

I have seen This question but I am not satisfied with answer. I connect to remote sftp server and I will do ls there I want to have the result of ls on my local machine. I don't want any thing extra to be saved, only the result of ls command. Can I save the result to a variable accessible on the local machine?

#!/usr/bin/expect

spawn sftp [e-mail]
expect "password:"
send "mypassword\n";
expect "sftp>"
send  "ls\n"  //save here
interact

解决方案

Here's how I would do it, with a more "traditional" approach that involves opening a file for writing the desired output (I like @kastelian 's log_file idea, though):

#!/usr/bin/expect

spawn sftp [e-mail]
expect "password:"
send "mypassword\n";
expect "sftp>"

set file [open /tmp/ls-output w]     ;# open for writing and set file identifier

expect ".*"     ;# match anything in buffer so as to clear it

send  "ls\r"

expect {
    "sftp>" {
        puts $file $expect_out(buffer)  ;# save to file buffer contents since last match (clear) until this match (sftp> prompt)
    }
    timeout {     ;# somewhat elegant way to die if something goes wrong
        puts $file "Error: expect block timed out"
    }
}

close $file

interact

The resulting file will hold the same two extra lines as in the log_file proposed solution: the ls command at the top, and the sftp> prompt at the bottom, but you should be able to deal with those as you like.

I have tested this and it works.

Let me know if it helped!
