## Filters
|
||||
|
||||
### Filter file
|
||||
|
||||
Set up a `.rsync-filter` file in any directory. If `rsync` is called with the `-F` option, the filtering rules in that file will be applied from that directory to all its subfolders.
|
||||
|
||||
```sh
|
||||
$ cat '.rsync-filter'
|
||||
- .DS_Store
|
||||
- .localized
|
||||
- .obsidian
|
||||
- .terraform*
|
||||
|
||||
+ **
|
||||
|
||||
$ rsync … -F
|
||||
```
|
||||
|
||||
The filter file excludes files from the source, but does nothing for the ones on the remote.<br/>
|
||||
If one wants to exclude files from the remote, they must be set explicitly using the `--exclude` option.
