new mac mini with snow leopard.
entering the following into the terminal: cd /usr/local
get the following message: -bash: cd: /usr/local: No such file or directory
not sure why?
You're getting this error because the directory /usr/local does not exist. I don't have a Snow Leopard install in front of me right now, but it's entirely possible that this directory doesn't exist by default -- nothing would be installed there in a stock install.
Try this command in the terminal instead: ls /usr
This lists the contents of the /usr directory.
Do you see "local" is in the list of directories in /usr? If not, it doesn't exist and that's why you can't cd to /usr/local.
