Question : Create a link based on the first letter of a file name

Is there a way to display the alphabet along the top of a web page in which the user will click a letter and links will be created to all the documents in a directory that begin with that letter? For example, a user clicks on the letter 'B' and all pdf files that have filenames beginning with 'B' will show up with links to those files. This needs to be written in PHP.

Thanks for any help on this....

Answer : Create a link based on the first letter of a file name

Are you certain you typed:
/etc/init.d/vsftpd stop
?

Strange things can happen when you are not root. It should have been:

sudo /etc/init.d/vsftpd restart

Maybe this will already straighten things out for you.
If you have a problem remembering to always prefix the 'sudo' command, issue
sudo -i
once at the beginning of a terminal session; this will simulate a root login shell.

This is an Ubuntu and Linux question. The zones you posted it in are very unlikely to give you practical and timely answers.
Good zones to ask this question in would have been:
