What does chmod 775 mean?
chmod 775 gives owner and group full, others read/execute. Like 755 but the group can also write. Common for shared upload or cache directories where the web server and a deploy user share a group.
| Who | Digit | Symbolic | Permissions |
|---|---|---|---|
| Owner (user) | 7 | rwx | read, write, execute |
| Group | 7 | rwx | read, write, execute |
| Others | 5 | r-x | read, execute |
Each digit is the sum of read (4), write (2) and execute (1). In ls -l the file shows as -rwxrwxr-x and a directory as drwxrwxr-x.
