I removed the only ACL on the /Applications directory by running Code: chmod -N /Applications when I was trying to get my XAMPP server running and displaying my default web page. I fixed my issue with displaying the default web page and now I need to change the ACL on the /Applications directory back to Everyone deny delete so I can lock my system back down. I have read the man page for chmod but I am having no luck setting it. This may be simple but I am a newbie when it comes to ACLs on directories and files and would like to get some assistance with this. Any suggestions or links to where I can get some further assistance with setting ACLs on directories and files?
