bash EOF in if statement

I am trying to do an action in a IF ELSE statement in Bash, but receive an error like this one:

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

Now I am quite new to this, so probably the solution to my problem should not be that difficult :)

if [ "$DAYNAME" = 'Sunday' ]; then
    echo 'The backup will be uploaded'
    ftp -n $HOST <<EOF
        quote USER $USER
        quote PASS $PASSWD
        put $filetoday
        delete ${filethreeweeksago}
        quit
    EOF
fi

Of course the vars are already filled.

I think it has to do with the EOF notation, because when i remove them, the problem disapears. Unfortunatly I don't know how to use the code without the EOF notation.

Can anyone tell me why this error is comming up?

The here document delimiter will not be recognized if it is indented.

You can fix it in one of two ways:

1.Simply remove the indentation, even though this may break formatting.

2.Use <<- instead of <<, and indent the script with tabs only (spaces will not be recognized).

Removing the indentation is preferred, since the script won't suddenly break if it's reformatted, copy-pasted, or saved with a different editor.

EOL inside If-Else

Syntax of EOL can be this type

if [ condition ]; then
    echo "Comment"
else
    cat >> file.txt <<-EOL

    EOL
fi

add a dash to EOF if you want to keep the tabs: from:

ftp -n $HOST <<EOF

to:

ftp -n $HOST <<-EOF

Drop the blanks and it should work:

    EOF
