Don't bother with that! In Tiger, the /.hidden file is still supported. In the Terminal, just do the following:
Code:
sudo -s
[enter password]
echo "var" >> /.hidden
echo "etc" >> /.hidden
...
I added the sudo part because he might not be the owner of /. Do this for each item you want to hide, replacing the quoted string with the name of the item. If the Finder doesn't hide the items right away, log out and log back in.
I don't think the contents of /.hidden need to be in alphabetical order, but if it doesn't work you could try that too.
Edit: Actually, scratch that. Just do this:
Code:
sudo touch /.hidden
[enter password]
open -a textedit /.hidden
That will first make sure the file exists, and then open it for editing in TextEdit. If prompted, choose to overwrite when you save.
