|
|||
|
||||
- File attributes are settable via `chattr` and offer an alternative, lower-level alternative to file permissions. For example, to protect accidental file deletion the immutable flag: `sudo chattr +i /critical/directory/or/file`
|
||||
|
||||
- Use `getfacl` and `setfcle` to save and restore file permissions. For example:
|
||||
```sh
|
||||
getfacl -R /some/path > permissions.txt
|
||||
setfacl --restore=permissions.txt
|
||||
```
