Detailed Explanation
The permission 710 gives the owner full access, allows the group to execute/traverse only, and blocks others completely.
Octal breakdown:
- 7 (Owner): read (4) + write (2) + execute (1) = full access
- 1 (Group): execute (1) only
- 0 (Others): no access
In symbolic notation this is rwx--x---. The owner has full control. Group members can only traverse the directory (access files by exact path) but cannot list its contents. Others are completely blocked.
This permission is useful for home directories on systems where a web server (in the user's group) needs to reach a specific subdirectory like public_html but should not be able to list the user's other files. It provides more security than 711 by blocking access from users not in the group.
Use Case
Used for user home directories on shared hosting where the web server group needs traversal access to serve public_html, but other users should not have any access.
