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 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.
Using $@ instead of $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS in Nautilus scripts could solve the problem with new line separators (which are used as delimiters in $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS and $NAUTILUS_SCRIPT_SELECTED_URIS).
So, the code will look like:
#!/bin/bash
for line in "$@"; do
if [[ "$line" = "" || "$line" = " " ]]; then
exit
else
unzip "$line" -d "temp"
fi
done
Also, this is handy when we need just pass selection to another app:
#!/bin/sh
baobab "$@"
Put single quotes around the variable name, like so:
#!/bin/bash
for line in '$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS'; do
if [[ "$line" = "" || "$line" = " " ]]; then
exit
else
unzip "$line" -d "temp"
fi
done
