# Preface
This section describes in brief some CLI commands. Please read [the general notes on the command line interface](index) before continuing.
# Importing newsfeeds from OPML
It's possible to import not only newsfeeds but also folders and Fever groups using OPML files. The process is simple:
```sh
sudo arsse import "user@example.com" "subscriptions.opml"
```
The importer is forgiving, but some OPML files may fail, with the reason printed out. Files are either imported in total, or not at all.
# Exporting newsfeeds to OPML
It's possible to export not only newsfeeds but also folders and Fever groups to OPML files. The process is simple:
```sh
sudo arsse export "user@example.com" "subscriptions.opml"
```
The output might look like this:
```xml
```
# Managing newsfeeds via OPML
Not all protocols supported by The Arsse allow modifying newsfeeds or folders, et cetera; additionally, not all clients support these capabilities even if the protocol has the necessary features. An OPML export/import sequence with the `--replace` import option specified, however, makes any kind of modification possible. For example:
```sh
# export your newsfeeds
sudo arsse export "user@example.com" "subscriptions.opml"
# make any changes you want in your editor of choice
nano "subscriptions.opml"
# re-import the modified information
sudo arsse import "user@example.com" "subscriptions.opml" --replace
```
