moving a file with spaces in name
===

I have a file in unix with name as "this is my file.xls"

I want to move it from one folder to other. I wrote the below lines:


    fileName="this is my file"
    myDate=20121125
 
    mv $FIRST_DIR/"${fileName}.xls" $SECOND_DIR/"${fileName}_${myDate}.xls"

However, this is not working. I am getting error as "file.xls is not a directory"

What is the correct way to do this?

Thanks for reading!
