Syntax error near unexpected token `elif'

问题:

./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,

./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?

Edit: When I add #!/bin/bash at the top, I get the following error:

interpreter "/bin/bash" not found
file link resolves to "/usr/bin/bash"
-bash: ./chkf: /bin/bash^M: bad interpreter: No such file or directory

回答1:

It's your line endings. Transferring it from Windows has left the CR/LF line endings on.

When I create a script then manually add the CR characters, I get exactly the same error:

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.

cat script.sh | sed '/\015/d' >newscript.sh

• CR character correspond to \015 octal representation as listed in ASCII

回答2:

it looks like you've got the "dos problem", embedded control-M's in your file. fix it with sed:

sed -i 's/\r//' chkf

回答3:

Two ways to resolve this

1) Using Sed:-

Syntax

sed -i 's/\r//' filename.txt

2) Using dos2unix command

Syntax

dos2unix fileName.txt fileName.txt

回答4:

Now that you've added the additional error message, I have a thought: the ^M is \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 ^M if it's not right through the file.

I got below error in my mail when i set up cron for magento.

/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.
