I also get access denied when clicking on CMSSW Framework. If I reopen the browser I can get back into the CMS Twiki but that is all.

Here is a brief list of frequently/commonly used UNIX commands:

• cp – copy files
• scp – secure copy files
• ls – list files (ls -l lists files with attributes)
• chmod – change attributes of files, etc. (chmod u+x … makes a file executable for you)
• cd – change directory
• mv – move files
• rm – remove files
• pwd – to find out in which directory you are currently

You can use e.g. “man ls” on the command line to find out more about a specific command. You could also try to google details …

If you have found out other useful commands, tricks, etc. let us know!
