Linux/Ubuntu服务器命令行使用百度网盘
软件简介与安装
软件简介
百度网盘在下载大文件的时候，很容易让人沮丧，那么不如我们把百度网盘的大文件下载任务放在长时间开机运行的服务器上，用命令行运行任务并挂在后台；服务器上的大文件/数据也可以后台上传至网盘备份。
linux下百度网盘的命令行客户端是bypy（baidu yun python）。客户端提供了丰富的命令行操作，并且支持多线程操作，可以方便的让我们在服务器上下载、上传、文件同步等操作。
软件安装与登录
由于是python客户端，所以使用pip工具进行下载，没有pip工具的可以先下载pip
sudo apt-get install pip通过pip --version查看pip版本。
正式安装bypy
pip install bypy登录百度网盘账号
user@ubuntu:~ $ bypy info
Please visit:
https://openapi.baidu.com/oauth/2.0/authorize?client_id=q8W
And authorize this app
Paste the Authorization Code here within 10 minutes.
Press [Enter] when you are done按照要求浏览器访问网站，获取一串口令后，输入并回车即可登录。此时会在网盘的“我的应用数据”文件夹下新建一个文件夹“bypy”，命令行执行命令时的默认网盘目录就是这个文件夹，把网盘文件放在这个文件夹里就可以通过命令bypy list列出来了。

positional arguments:
command operations (quota, list, etc)
optional arguments:
-h, --help show this help message and exit

-d, --debug set debugging level (-dd to increase debugging level, -ddd to enable HTPP traffic debugging as
well (very talkative)) [default: 0]
-v, --verbose set verbosity level [default: 0]
-r RETRY, --retry RETRY
number of retry attempts on network error [default: 5 times]
-q, --quit-when-fail quit when maximum number of retry failed [default: False]
-t TIMEOUT, --timeout TIMEOUT
network timeout in seconds [default: 300]
-s SLICE, --slice SLICE
size of file upload slice (can use '1024', '2k', '3MB', etc) [default: 20 MB]
--chunk CHUNK size of file download chunk (can use '1024', '2k', '3MB', etc) [default: 20 MB]
-e, --verify verify upload / download [default : False]
-f, --force-hash force file MD5 / CRC32 calculation instead of using cached value
--no-resume-download resume instead of restarting when downloading if local file already exists [default: True]
--include-regex INCREGEX
regular expression of files to include. if not specified (default), everything is included.
for download, the regex applies to the remote files; for upload, the regex applies to the
local files. to exclude files, think about your regex, some tips here:
https://stackoverflow.com/questions/406230/regular-expression-to-match-string-not-containing-
a-word [default: ]
--on-dup ONDUP what to do when the same file / folder exists in the destination: 'overwrite', 'skip',
'prompt' [default: overwrite]
--no-symlink DON'T follow symbol links when uploading / syncing up
--disable-ssl-check DON'T verify host SSL cerificate
--cacerts CACERTS Specify the path for CA Bundle [default: None]
--mirror MIRROR Specify the PCS mirror (e.g. bj.baidupcs.com. Open
'https://pcs.baidu.com/rest/2.0/pcs/manage?method=listhost' to get the list) to use. [default:
pcs.baidu.com]
--select-fastest-mirror
Let the program run some tests and select the fastest PCS mirror it detectes. [default: False]
--rapid-upload-only only upload large files that can be rapidly uploaded
--resume-download-revert-back RCOUNT
Revert back at least RCOUNT download chunk(s) and align to chunk boundary when resuming the
download. A negative value means NO reverts. [default: 1]
--move Delete source files/directories after download/upload/syncdown/syncup is successful (This will
force verification of the files). [default: False]
--processes PROCESSES
Number of parallel processes. (Only applies to dir sync/dl/ul). [default: 1]
--downloader DOWNLOADER
downloader to use (use python if not specified). valid values: ['aria2'] [default: ]
--downloader-arguments DOWNLOADER_ARGS
arguments for the downloader: normally, the string is the arguments to be passed to the
downloader. however, when it begins with '@', it will be treated as the name of file, whose
contents will be used as the downloader arguments (example: when specifying '@args.txt', file
contents of 'args.txt' will be used as the downloader arguments, not the string '@args.txt'
itself). you can also use environment variable 'DOWNLOADER_ARGUMENTS' to specify the
downloader arguments (the environment variable has lower priority compared to this argument).
default values: {'aria2': '-c -k10M -x4 -s4 --file-allocation=none'}
--config-dir CONFIGDIR
specify the config path [default: /home/lichen/.bypy]

但是常用的指令比较简单，主要就是下载、上传和同步。如果不指定文件夹下，操作的就是当前文件夹和网盘上的bypy文件夹。
下载
bypy download filename #下载文件到当前文件夹下
bypy download remote/path/filename local/path/filename #下载网盘文件至本地指定路径上传
bypy upload filename #上传文件到bypy文件夹下
bypy upload local/path/filename remote/path/filename #上传文件至网盘指定路径同步
bypy syncup local/path remote/path #同步本地到云端
bypy syncdown remote/path local/path #同步云端到本地服务器后台运行命令
更常见的是，我们在下载大文件时，希望进程能在后台运行，尤其是当我们是ssh到服务器进行操作时，一旦退出ssh，进程就停止了。此时我们用nohup命令，使得进程不会因此而关闭；配合&参数让进程在后台运行。此时程序输出会被写入文件nohup.out，供我们查看。
以下载文件为例
nohup bypy download filename &
