Useful AFS Information
----------------------

Access Control List (ACL):
  An ACL contains information on permissions (read, write, etc.) for a directory
  "read" permission is listed as rl
  "write" permission is listed as rlidwk

Show Access Control List for a directory:
  command: fs listacl <directory_name>                      (abbreviated fs la)
             where <directory_name> is the name of the directory
  Examples: 
    fs la data        -- shows access control list for subdirectory "data"
    fs la .           -- shows ACL for the current directory

Set Access Control List for a directory:
  command: fs setacl <directory_name> <user|group> <acl>    (abbreviated fs sa)
             where <directory_name> is the name of the directory
                   <user|group> is the username or the name of the group
                   <acl> is the access control list
  Note: this command works on a given directory but not its subdirectories
  Examples:
    fs sa data smith write       -- give write permission to user "smith" for 
                                    subdirectory "data"
    fs sa . jones read           -- give read permission to user "jones" for 
                                    current directory
    fs sa dv01 smith:fmri write  -- give write permission to smith's fmri group 
                                    (named "smith:fmri") for subdirectory "dv01"

Set Access Control List for a directory and all of its subdirectories:
  command: chmodafs <directory_name> <user|group> <acl>  
  Example:
    chmodafs data smith write  -- give write permission to user "smith" for 
                                  subdirectory "data" and its subdirectories
