### Configuration
|
||
|
|
Opensend allows configuration by TOML and by command line flags. It looks at the following paths for configs in the specified order:
|
||
|
|
|
||
|
|
#### Config files
|
||
|
|
|
||
|
|
1. Config path from `--config` flag
|
||
|
|
2. `~/.config/opensend.toml`
|
||
|
|
3. `/etc/opensend.toml`
|
||
|
|
|
||
|
|
#### Command line flags
|
||
|
|
|
||
|
|
```text
|
||
|
|
Usage of opensend:
|
||
|
|
-d string
|
||
|
|
Data to send
|
||
|
|
-dest-dir string
|
||
|
|
Destination directory for files or dirs sent over opensend (default "/home/arsen/Downloads")
|
||
|
|
-r Receive data
|
||
|
|
-s Send data
|
||
|
|
-send-to string
|
||
|
|
Use IP address of receiver instead of mDNS
|
||
|
|
-skip-mdns
|
||
|
|
Skip zeroconf service registration (use if mdns fails)
|
||
|
|
-t string
|
||
|
|
Type of data being sent
|
||
|
|
```
|
||
|
|
|
||
|
|
The purpose of the mdns-skipping flags is to account for the iSH app in iOS, as the mdns resolver and registration fails on it.
