Commands

Slash Commands

Crow supports slash commands typed into the message composer. These commands control channels, storage, and other node functions.

Channel Commands

/channels

/channels local

List public channels visible on the local AREDN network. Channels you can join are clickable.

/channels world

List public channels visible across the wider mesh network (requires a bridge node). Falls back to local channels if no bridge is available.

/channels join <name> [key]

Join a channel by name. Channels prefixed with # generate their key automatically from the name. Channels prefixed with % use the open key. Other channels require an explicit key.

Examples:

/channels join #mychannel
/channels join %public
/channels join MyChannel base64keyhere==

/channels leave <name>

Leave a channel by name.

/channels leave #mychannel

Storage Commands

These commands manage where Crow stores messages, images, and Winlink forms. See USB Storage for full setup instructions.

/storage status

Show current storage state: mode (internal/usb/degraded), root directory, image directory, mountpoint, and USB port availability.

/storage usb scan

Detect removable USB storage devices attached to the node. Lists device path, model, size, and mount status.

/storage usb enable

Mount and activate USB storage. Auto-detects the first removable USB drive, mounts it, creates the required directories, and migrates existing data.

/storage usb disable

Return to internal node storage. The USB drive is not unmounted or erased.

/storage quota images <mb>

Set the image storage quota in megabytes (1–65536). Oldest images are pruned when the quota is exceeded.

/storage quota images 128

#groupname message	Send to all members of a configured group
#groupname CALL1, CALL2 message	Send to an inline list of stations
