When I try to run this file, this is the error I get:

iMac:no-ip_uninstaller danijelj$ ./noip-remove.sh 
./noip-remove.sh: line 87: unexpected EOF while looking for matching `"'
./noip-remove.sh: line 136: syntax error: unexpected end of file
iMac:no-ip_uninstaller danijelj$ 

Does anybody have any idea why line 87 is causing that problem, or 136 is giving the unexpected end of file issue to me? There isn't even 136 lines in this. It is a rip from the original file on my computer as above.

In the end I changed the whole script around, and it's now in a final revision, and ready to be converted into a Mac App, but this is what I ended up doing:

# Function Show script help
function showHelp {
        clear
        echo "No-IP Uninstaller $version"
        echo 
        echo 'Usage: sh $1 [option]'
        echo 
        echo 'Option:'
        echo '   -h    This help file'
        echo '   -r    Remove No-IP, no restart'
        echo '   -u    Completely uninstall, restart required'
        echo 
        echo "Advised Usage: sh $0 -u"
        echo 
}   # end of showHelp

The updated file looks nothing like the version above, so it's hard to compare. What a shame.
