使用bash here-doc“文件意外末尾"时出错. [英] Error when using a bash here-doc "unexpected end of file"

问题描述

我在代码的最后一行(为空)上标记了以下错误:

I get the following error that is flagging on the last line of my code (which is empty):

syntax error: unexpected end of file

我不知道为什么这么说.我只是想使用here-doc进行ssh连接:

I can't figure out why it's saying this. I'm simply trying to use a here-doc for an ssh connection:

#!/bin/sh

connectToServer() {
   ssh -t root@$1 <<- ENDSSH
      echo "Connected to server!"
   ENDSSH
}

connectToServer $1

此代码有什么问题?

编辑

感谢那些帮助我解决此问题的人.我的脚本有几处错误；我在行上使用空格:

Thanks to those of you who helped me to troubleshoot this. There were a couple of things wrong with my script; I was using spaces on the line:

echo "Connected to server" 

代替制表符.我在结束ENDSSH之前也包含空格，这导致了EOF.这些更改是我的问题的一部分，但解决该问题的最后一件事是删除了在我关闭ENDSSH之后出现的另一个空格字符.

instead of tab characters. I was also including spaces before the closing ENDSSH which was causing the EOF. These changes were a part of my problem, but the final thing that resolved it was removing an additional space character that appeared AFTER my closing ENDSSH.

推荐答案

问题是关闭ENDSSH之前的空格.删除ENDSSH之前的所有前导空格.

Problem is spaces before closing ENDSSH. Take out all the leading spaces before ENDSSH.
