Here are the most commonly used values for setting permissions on directories and files.
| directories | files | result |
|---|---|---|
| 0700 | 0600 | read/write for owner only. Owner must be the same as the PHP process user. |
| 0770 | 0660 | read/write for owner and group. The PHP process user needs to be in the user group |
| 0777 | 0666 | read/write for everyone. Dangerous because everybody with access to the server may write and delete your files. Use only as a last resort on trusted machines, NOT on a cheap shared hosting server. |
grep -Ev '^($|#)' data/deleted.files | xargs -n 1 rm -vf
