file: files sending/receiving/management

file group all commands related to file management, and allows you to send easily a file to a contact or device from the command line.


Send a file to a contact.

The file will be sent using best available method (which is Jingle File Transfer when available), and will try to send the file in P2P when possible. If P2P is possible, the signal is sent through the server (metadata, negotiation, etc.), while the file itself goes directly from the source device to the target device. When P2P is not possible, the file may go through the server or an other one (if a proxy is used for instance).

When sending a file, you specify one or more file(s) to send, and the either the bare jid or the full jid of the target device. If bare jid is specified, the main resource will be used.

You’ll usually want to see the progression of the transfer, use -P, --progress for that.

If you send several files at once, you may want to use -b, --bz2 to group them in a single compressed tar.bz2 archive (the client receiving the files will then receive a single file, than the user can then decompress).

By default the name of the source file is used, but you use -n NAME, --name NAME to specify another one.

The path and namespace (set with -d PATH, --path PATH and -N NAMESPACE, --namespace NAMESPACE) are non-standard metadata used by Libervia to organise files (PATH being like a file path on locale file system, and NAMESPACE being a name to associate to a group of files, for instance for a photo album).


Send a file to Louise, with a progress bar:

$ li file send -P some_file.ext

Send a picture to a file sharing component, putting it in the holidays namespace, in the /some/path path:

$ li file send -P -N holidays -d /some/path some_photo.jpg


Ask to get a file from a device/sharing service. A file is requested using one or more metadata, which can be the file name (with -n NAME, --name NAME), its hash (with -H HASH, --hash HASH and the algorithm may be specified with -a HASH_ALGO, --hash-algo HASH_ALGO), its path (with -d PATH, --path PATH) and its namespace (with -N NAMESPACE, --namespace NAMESPACE). Note that PATH and NAMESPACE are Libervia specific and not (yet?) XMPP standards.

If you already know the hash, it’s the most efficient and recommended way to retrieve a file.

You need to specify the full jid of the device or the sharing service as a positional argument.

By default the file is downloaded in current directory, but you can specify an other one (and an other filename) with -D DEST, --dest DEST.

If you want to see progression of the transfer, use -P, --progress.


Request a file names some_file.jpg in path /photos/demo_album at service, with a progress bar:

$ li file request -P -d photos/demo_album -n some_file.jpg

Request file with given sha-256 hash (which is default hash algorithm, so we don’t specify it), and save it to file dest_file.txt:

$ li file request -H f2ca1bb6c7e907d06dafe4687e579fce76b37e4e93b7605022da52e6ccc26fd2 -D dest_file.txt


Wait for a file (or several ones) to be received, and accept it if it match criteria.

You should specify which jid you are expecting a file from, using the positional arguments. If you don’t, all files will be accepted, which can be dangerous if some malicious user send you a file at this moment.

To see progression (this is recommended), you can use the -P, --progress options.

By default, if a file with the same name as the proposed one exists, the transfer will be denied. You can override this behaviour with -f, --force, but be sure to absolutely trust the sender in this case, as the name is chosen by her, and could be malicious, or it could override an important file.

If you expect several files, you can use the -m, --multiple, in this case the command won’t stop after the file received file, and you’ll have to manually stop it with Ctrl-C or by sending a SIGTERM.

File(s) will be written in the current directory, but you may specify an other destination with --path DIR.


Accept and receive the next file, save it to local directory and show a progress bar:

$ li file receive --progress

Several files are expected from Louise, accept them and store them do ~/Downloads/Louise:

$ li file receive --multiple --path ~/Downloads/Louise


Download a file from an URI. This commands handle URI scheme common with XMPP, so in addition to http and https, you can use it with aesgcm scheme (encrypted files with key in URL, this is notably used with OMEMO encryption).

As usual, you can use -P, --progress to see a progress bar.


Download an encrypted file with a progress bar, and save it to current working directory with the same name as in the URL (some_image.jpg). The URL fragment part (after #) is used for decryption, so be sure to not leak the URL when you manipulate one:

$ li file get -P "aesgcm://"


Upload a file to your XMPP server (or an other entity if specified). The upload will be done using XEP-0363 (HTTP File Upload), and the public URL to retrieve the file will be printed. Note that anybody knowing this URL can download the file you’ve uploaded.

The path to the file to upload is expected as first argument, then optionally the entity of the service to upload too (by default, this is autodetected if your server offers this feature).

As usual, you can use -P, --progress to see a progress bar.

You can encrypt the file using AES GCM with the -e, --encrypt argument. You will then get an aesgcm:// link instead of the usual https, this link contains the decryption key (in the fragment part) so be sure to not leak it and to transmit it only over encrypted communication channels.


Upload a document to a server:

$ li file upload -P ~/Documents/something_interesting.odt

Encrypt and upload a document to server:

$ li file upload -P -e ~/Documents/something_secret.odt
