Understanding File Permissions in AFS

In AFS, file permissions are specified for each directory, and apply to the directory and to all the files that directory contains.

These permissions do not apply to any subdirectory within a directory. However, any newly created subdirectory will inherit the permissions of its parent directory.

Seven Access Types You Can Grant


  • Ability to look at the directory's ACL and to list the contents of the directory (what files and directories are in it). It does not give read access to the files.


  • Read access on a directory allows reading of all the files in a directory.


  • Write access on a directory grants permission to modify existing files and subdirectories within a directory, and to change permissions on the files in that directory.


  • Insert access on a directory implies permission to create files or subdirectories in the directory.


  • Delete access on a directory gives the ability to remove files or empty subdirectories from the directory.


  • With administer access on a directory, it is possible to change the ACL of the directory.


  • A user with lock access on a directory can put advisory locks on files within the directory.
