(Nautilus Scripts) $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS; have problems with space

So the script is:

#!/bin/bash

for line in $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS; do
   if [[ "$line" = "" || "$line" = " " ]]; then
      exit
   else
      unzip "$line" -d "temp"
   fi
done

It works well and unzips the file. But if the file is named with a space (eg: Leon - 1994.zip) it will not work and the $line will be

1st time: /home/citybong/Downloads/Leon

2nd time: -

3rd time: 1994.zip

Edit: I fount a link http://g-scripts.sourceforge.net/faq.php for the question: "My script can't handle multiple files/files with spaces" but i am kinda newbie to bash scripting and i can't understand their solutions

IFS is by default set to space, that's why your string is being divided into spaces. Just set it to the newline with the following code:

IFS_BAK=$IFS
IFS="
"

for line in $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS; do
    whatever $line
done

IFS=$IFS_BAK

You don't need to mess with IFS:

echo "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" | while read filename; do
    unzip "$filename" -d temp
done

I had a similar problem and it turns out that echo preserves newlines in double quotes, but without quotes changes them to spaces.
