Whats the deal with permissions? How do I change them?
Each file or folder is considered to be owned by one user and one group (usually the main group to which that user belongs). There are a set of permissions associated with each file or folder that determines what actions on that file or folder are allowed for a particular user. You can see the ownership and permissions for a file or folder by using the ‘ls’ command with the “-l” option – i.e. with the command ‘ls -l’. (Since it is sometimes difficult to distinguish lowercase L’s from I’s and 1’s, I note that phonetically this command is “ell ess minus ell”.
