Shell Programming and Scripting

Hello, I'm new to UNIX and using BASH shell. Using VI to script and I can't figure this out. Basically, I'm trying to write a script that will ask for a filename, then ask for a name. It will then redirect this to a new file (whatever was choosen for the file name. These were my instructions:


This is what I have so far.

Code:

if [ -z $filename ]
then
   echo No scriptname.
   end
else
   echo $filename
fi

echo -n "Please type your name: "
read yourname

if [ -z $yourname ]
then
    echo No name given.
    end
else
    echo echo Script: $filename >> $filename
    echo echo Author: $yourname >> $filename
    echo echo Date: >> $filename
    date >> $filename
    chmod 755 $filename >> $filename
    echo echo Hello, world\!\! >> $filename
    echo echo "I am the script $0" >> $filename

Whenever I do this, the last like "I am the script $0" will display the original file name, that is sgen2, rather than the new filename. Any help would be GREATLY appreciated!
