第16行的语法错误

Question

对我来说，语法似乎写得正确，但我得到了第16行的错误....任何想法？

#!/bin/sh 

#This is script is meant to be an add on to another one I'm using. Based on the return code output it will mail me the message. 

read -p "What is the file name? " variable 
rc = $? 

ls -al $variable 
if [[ $rc != 0 ]]; then 
     mail -s "$variable script did not complete" email address -- -f email address \ 
     << EOF Your script has failed with error code $rc << EOF; 
elif [[ $rc = 0 ]]; then 
     mail -s "Your script completed" email address -- -f email address \ 
     << EOF Your script completed with error code $rc. << EOF; 
fi 

粘贴似乎已经搞乱了格式。下面是引擎收录链接：

的here document开始<< EOF需要其最终EOF在自己的行的开始。

mail -s "$variable script did not complete" email address -- -f email address << EOF 
Your script $variable has failed with error code $rc. 
EOF 

如果使用标签（标签严格）缩进，你可以使用：

mail -s "$variable script did not complete" email address -- -f email address <<-EOF 
    Your script $variable has failed with error code $rc. 
    EOF 

（我漫不经心地假设你mail命令的语法是确定的，但我不相信这一点，即使是GNU getopt()重新排序选项。如果这两个词email address是email1@us.example.com和email2@uk.example.com或类似的东西，那么这将是更近确定。至于我自己，我还是喜欢以前的参数选项。）

我还希望将失败的脚本名称包含在电子邮件正文中以及主题行中。
