Syntax error near unexpected token `elif'
提问by Strawberry
./chkf: line 30: syntax error near unexpected token `elif'
'/chkf: line 30: `elif [ -f "$object" ] ; then
if [ -d "$object" ] ; then
message="$message a directory"
elif [ -f "$object" ] ; then
message="$message a regular file."
else
message="$message not a known file type"
fi
Also this,
还有这个，
./chkf: line 38: syntax error near unexpected token `else'
'/chkf: line 38: `else
if [ -w "$object" ] ; then
write="writeable"
else
write="not writeable"
fi
What is wrong with this? It seems to be correct. I tried so many variations and cannot figure out what is wrong. Is there some kind of invisible character? If so, is there a command to strip it?
这有什么问题？这似乎是正确的。我尝试了很多变体，但无法弄清楚出了什么问题。是否有某种无形的性格？如果是这样，是否有删除它的命令？
Edit:When I add #!/bin/bashat the top, I get the following error:
编辑：当我#!/bin/bash在顶部添加时，出现以下错误：
interpreter "/bin/bash" not found
file link resolves to "/usr/bin/bash"
-bash: ./chkf: /bin/bash^M: bad interpreter: No such file or directory

It's your line endings. Transferring it from Windows has left the CR/LFline endings on.
这是你的行尾。从 Windows 传输它使CR/LF行尾保持不变。
When I create a script then manually add the CRcharacters, I get exactly the same error:
当我创建一个脚本然后手动添加CR字符时，我得到完全相同的错误：
qq.sh: line 3: syntax error near unexpected token `elif'
'q.sh: line 3: `elif [ 1 == 1 ] ; then
You can fix it by removing the CR character from CR/LF line endings.
您可以通过从 CR/LF 行尾删除 CR 字符来修复它。
cat script.sh | sed '/5/d' >newscript.sh
- CR character correspond to
\015octal representation as listed in ASCII
- CR 字符对应
\015于ASCII 中列出的八进制表示

Now that you've added the additional error message, I have a thought: the ^Mis \r, which is the Mac OS X line ending or part of the Windows line ending - Linux uses \n only as EOL. If you edit in vim, you should be able to see the ^Mif it's not right through the file.
现在您已经添加了额外的错误消息，我有一个想法：它^M是 \r，它是 Mac OS X 行结尾或 Windows 行结尾的一部分 - Linux 仅将 \n 用作 EOL。如果您在 中进行编辑vim，您应该能够^M通过文件查看它是否不正确。

I got below error in my mail when i set up cron for magento.
当我为 magento 设置 cron 时，我的邮件中出现以下错误。
/bin/sh: -c: line 0: syntax error near unexpected token `newline'
/bin/sh: -c: line 0: `php /home/pooja/public_html/magento/journal/cron1.php >'
I found solution for that is i remove newline space from my cron1.php file. and its work.
我找到的解决方案是从我的 cron1.php 文件中删除换行符空间。和它的工作。
