seaf-cli is command line interface for seafile client.

Subcommands:

    init:             create config files for seafile client
    start:            start and run seafile client as daemon
    stop:             stop seafile client
    list:             list local libraries
    status:           show syncing status
    download:         download a library from seafile server
                          (using libary id)
    download-by-name: download a library from seafile server
                          (using library name)
    sync:             synchronize an existing folder with a library in
                          seafile server
    desync:           desynchronize a library with seafile server
    create:           create a new library


Detail
======

Seafile client stores all its configure information in a config dir. The default location is `~/.ccnet`. All the commands below accept an option `-c <config-dir>`.

init
----
Initialize seafile client. This command initializes the config dir. It also creates sub-directories `seafile-data` and `seafile` under `parent-dir`. `seafile-data` is used to store internal data, while `seafile` is used as the default location put downloaded libraries.

    seaf-cli init [-c <config-dir>] -d <parent-dir>

start
-----
Start seafile client. This command starts `seaf-daemon`, which manages all the files.

    seaf-cli start [-c <config-dir>]

stop
----
Stop seafile client.

    seaf-cli stop [-c <config-dir>]


Download by id
--------
Download a library from seafile server (using library id)

    seaf-cli download -l <library-id> -s <seahub-server-url> -d <parent-directory> -u <username> -p <password> [-a <2fa-code>]


Download by name
--------
Download a library from seafile server (using library name)

    seaf-cli download -L <library-name> -s <seahub-server-url> -d <parent-directory> -u <username> -p <password> [-a <2fa-code>]


sync
----
Synchronize a library with an existing folder.

    seaf-cli sync -l <library-id> -s <seahub-server-url> -d <existing-folder> -u <username> -p <password> [-a <2fa-code>]

desync
------
Desynchronize a library from seafile server

    seaf-cli desync -d <existing-folder>

create
------
Create a new library

    seaf-cli create -s <seahub-server-url> -n <library-name> -u <username> -p <password> [-a <2fa-code>] -t <description> [-e <library-password>]
