Windows Permissions and Unix Mapping
| ID | Windows Permission | Included Permissions | Windows Notes | Unix Equivalent |
|---|---|---|---|---|
| FC | Full Control | M, CP, TO, RX, DS, L (ALL) | rwx (Read, Write, Execute) | |
| M | Modify | R, W, D | rwx (Read, Write, Execute) | |
| RX | Read & Execute | R, T | (Does not include L as a separate permission, but allows listing of folder contents) | rx (Read, Execute) |
| R | Read | RA, REA | r (Read) | |
| RA | Read Attributes | None | r (Read) | |
| REA | Read Extended Attributes | None | r (Read) | |
| T | Traverse Folder/Execute File | None | x (Execute) | |
| L | List Folder Contents | None | (is equivalent to RX on folders, allowing the user to view and list folder contents) | r (Read) |
| W | Write | WA, WEA | w (Write) | |
| WA | Write Attributes | None | Not directly equivalent in Unix. Unix does not have a separate permission for writing file attributes. | |
| WEA | Write Extended Attributes | None | Not directly equivalent in Unix. Unix does not have a separate permission for writing extended attributes. | |
| D | Delete | None | Not directly equivalent in Unix. Deletion of a directory or file is controlled by the permissions of the parent directory. | |
| DS | Delete Subfolders and Files | None | Not directly equivalent in Unix. In Unix write permission (`w`) on a directory allows deletion of files within that directory, but not deletion of the directory itself or its subdirectories. | |
| CP | Change Permissions | None | w (Write) | |
| TO | Take Ownership | None | Not directly equivalent in Unix. Ownership in Unix is managed separately from permissions. |
NFSv4 ACL Permissions r - Read Data / List Directory:
Allows reading the contents of a file or listing the contents of a directory. w - Write Data / Add File:
Allows modifying a file or adding a new file in a directory. x - Execute / Traverse:
Allows executing a file (if it is an executable) or traversing a directory. p - Append Data / Add Subdirectory:
Allows appending data to a file or adding a subdirectory within a directory. a - Append Data / Modify Directory:
Allows appending data to a file or modifying a directory. A - Read Attributes:
Allows reading basic attributes of a file or directory (e.g., timestamps, file size). R - Read Named Attributes:
Allows reading extended attributes associated with a file or directory. W - Write Named Attributes:
Allows writing or modifying extended attributes associated with a file or directory. c - Read ACL:
Allows reading the Access Control List of a file or directory. C - Write ACL:
Allows modifying the Access Control List of a file or directory. o - Write Owner:
Allows changing the ownership of a file or directory. s - Synchronize:
Ensures that file changes are synchronized to stable storage immediately. d - Delete:
Allows deleting a file or directory. D - Delete Child:
Allows deleting a file or directory within a directory. t - Read Attributes (NFSv4 specific):
Allows reading attributes related to the ACL. T - Write Attributes (NFSv4 specific):
Allows modifying attributes related to the ACL. N - Read Named Attributes (NFSv4 specific):
Allows reading named attributes specific to NFSv4.
Read (rxaRc): read, execute/traverse, append, read named attributes, read ACL. Modify (rwxpdcaARWco): read, write, execute/traverse, append, delete, read ACL, append/modify directory, read attributes, read/write named attributes, write owner. Traverse (x): execute/traverse directory. Full Control (rwxpdDaARWcCos): all permissions including delete child, synchronize, and full control over attributes and ACLs.
