c# - 带有标准输入重定向的 WinSCP ExecuteCommand？

Question

给定:

var linuxCommmand = "/opt/ndmcli -x"; 
var linuxOptions = "sel stat pnum=157 detail=yes;\nquit;"; 
SSH.ExecuteCommand(String.Format("{0} <<!!\r\n{1}\r\n!!\r\n", linuxCommand, linuxOptions)); 

查询 session 日志显示命令是正确的:

2016-10-25 14:12:49.433 Script: call /opt/cdunix/ndm/bin/ndmcli -x <<!!
2016-10-25 14:12:49.433 sel stat pnum=157 detail=yes;
2016-10-25 14:12:49.433 quit;
2016-10-25 14:12:49.433 !!
2016-10-25 14:12:49.433 Executing user defined command.
2016-10-25 14:12:49.433 /opt/cdunix/ndm/bin/ndmcli -x <<!!
2016-10-25 14:12:49.433 sel stat pnum=157 detail=yes;
2016-10-25 14:12:49.433 quit;
2016-10-25 14:12:49.433 !! ; echo "WinSCP: this is end-of-file:$?"
2016-10-25 14:13:04.437 Waiting for data timed out, asking user what to do.
2016-10-25 14:13:04.437 Asking user:
2016-10-25 14:13:04.437 **Host is not communicating for 15 seconds.
2016-10-25 14:13:04.437 
2016-10-25 14:13:04.437 Wait for another 15 seconds?** ()

有什么原因我不能在 WinSCPNet 的 ExecuteCommand 中使用标准输入重定向？

谢谢!

****更新****奇怪的是，如果我添加尾随空格:

var linuxCommmand = "/opt/ndmcli -x"; 
var linuxOptions = "sel stat pnum=157 detail=yes;\nquit;"; 
SSH.ExecuteCommand(String.Format("{0} <<!!\r\n{1}\r\n!!\r\n ", linuxCommand, linuxOptions)); 

一切正常:

2016-10-25 15:58:03.489 Script: call /opt/cdunix/ndm/bin/ndmcli -x <<!!

2016-10-25 15:58:03.489 sel stat pnum=157 detail=yes;
2016-10-25 15:58:03.489 quit;

2016-10-25 15:58:03.489 !!

2016-10-25 15:58:03.489  
2016-10-25 15:58:03.489 Executing user defined command.
2016-10-25 15:58:03.489 /opt/cdunix/ndm/bin/ndmcli -x <<!!

2016-10-25 15:58:03.489 sel stat pnum=157 detail=yes;
2016-10-25 15:58:03.489 quit;

2016-10-25 15:58:03.489 !!

2016-10-25 15:58:03.489   ; echo "WinSCP: this is end-of-file:$?"

Answer 1

新行将完全混淆 WinSCP。

命令实际上没有正确执行，因为尾随的 !! 必须单独在一行，但事实并非如此。

您必须将所有内容放在一行中。

这可以工作:

( echo sel stat pnum=157 detail=yes; & echo quit; ) | /opt/cdunix/ndm/bin/ndmcli -x
