Syntax error: end of file unexpected (expecting "then")

Question

I am making this code for a minecraft server plugin updater I am a new shell scripter so I don't know alot...
when I run this code I get a error:

#!/bin/sh
export PATH=$PATH:.
#Options
PLUGINDOWNLOADLINK=http://api.bukget.org/3/plugins/bukkit/$PLUGINNAME/latest/download
# Plugin folder
if [ -f $PWD\plugins ]; then
PLUG=$PWD\plugins 
else
PLUG=$PWD\plug-ins
fi

cd $PLUG

if [ ! -f .\update ]; then
mkdir update
echo Making Directory "update"..
fi

# Plugins Found
    for i in $( ls );
    do
        PLUGINNAME=$i
    done
    cd .\update

    wget $PLUGINDOWNLOADLINK

    # No Plugins Found
    if [ ! -f $PLUG ]; then
    echo
echo
echo    No plugin found.
echo
echo
echo
echo   Plugins can be downloaded here:
echo   http://dev.bukkit.org/bukkit-plugins
fi

# stop 
sleep 3s
exit

I get this error:

Syntax error: end of file unexpected (expecting "then")

so I put "then" in the place it wanted me to and ran it again:
it gave me this error now:

Syntax error: end of file unexpected

I wrote it on windows 7 notepad++
how can I fix this?

Answer 1

I have met the same problem. And the problem is the format of the file is "dos", but in linux shell requires "unix", so I install the "dos2unix"

$ sudo apt-get install dos2unix

or if you use emacs, you can do this:

C-x RET f unix

Good luck :)
