Method Details |
Create an SFTP client from an existing `.Channel`. The channel should already have requested the ``"sftp"`` subsystem. An alternate way to create an SFTP client context is by using `from_transport`. :param .Channel sock: an open `.Channel` using the ``"sftp"`` subsystem :raises SSHException: if there's an exception while negotiating sftp
|
Create an SFTP client channel from an open `.Transport`. :param .Transport t: an open `.Transport` which is already authenticated :return: a new `.SFTPClient` object, referring to an sftp session (channel) across the transport |
Close the SFTP session and its underlying channel. .. versionadded:: 1.4 |
Return the underlying `.Channel` object for this SFTP session. This might be useful for doing things like setting a timeout on the channel. .. versionadded:: 1.7.1 |
Return a list containing the names of the entries in the given ``path``. The list is in arbitrary order. It does not include the special entries ``'.'`` and ``'..'`` even if they are present in the folder. This method is meant to mirror ``os.listdir`` as closely as possible. For a list of full `.SFTPAttributes` objects, see `listdir_attr`. :param str path: path to list (defaults to ``'.'``) |
Return a list containing `.SFTPAttributes` objects corresponding to files in the given ``path``. The list is in arbitrary order. It does not include the special entries ``'.'`` and ``'..'`` even if they are present in the folder. The returned `.SFTPAttributes` objects will each have an additional field: ``longname``, which may contain a formatted string of the file's attributes, in unix format. The content of this string will probably depend on the SFTP server implementation. :param str path: path to list (defaults to ``'.'``) :return: list of `.SFTPAttributes` objects .. versionadded:: 1.2 |
Open a file on the remote server. The arguments are the same as for Python's built-in `python:file` (aka `python:open`). A file-like object is returned, which closely mimics the behavior of a normal Python file object, including the ability to be used as a context manager. The mode indicates how the file is to be opened: ``'r'`` for reading, ``'w'`` for writing (truncating an existing file), ``'a'`` for appending, ``'r+'`` for reading/writing, ``'w+'`` for reading/writing (truncating an existing file), ``'a+'`` for reading/appending. The Python ``'b'`` flag is ignored, since SSH treats all files as binary. The ``'U'`` flag is supported in a compatible way. Since 1.5.2, an ``'x'`` flag indicates that the operation should only succeed if the file was created and did not previously exist. This has no direct mapping to Python's file flags, but is commonly known as the ``O_EXCL`` flag in posix. The file will be buffered in standard Python style by default, but can be altered with the ``bufsize`` parameter. ``0`` turns off buffering, ``1`` uses line buffering, and any number greater than 1 (``>1``) uses that specific buffer size. :param str filename: name of the file to open :param str mode: mode (Python-style) to open in :param int bufsize: desired buffering (-1 = default buffer size) :return: an `.SFTPFile` object representing the open file :raises IOError: if the file could not be opened. |

Remove the file at the given path. This only works on files; for removing folders (directories), use `rmdir`. :param str path: path (absolute or relative) of the file to remove :raises IOError: if the path refers to a folder (directory) |
Remove the file at the given path. This only works on files; for removing folders (directories), use `rmdir`. :param str path: path (absolute or relative) of the file to remove :raises IOError: if the path refers to a folder (directory) |
Rename a file or folder from ``oldpath`` to ``newpath``. :param str oldpath: existing name of the file or folder :param str newpath: new name for the file or folder :raises IOError: if ``newpath`` is a folder, or something else goes wrong |
Create a folder (directory) named ``path`` with numeric mode ``mode``. The default mode is 0777 (octal). On some systems, mode is ignored. Where it is used, the current umask value is first masked out. :param str path: name of the folder to create :param int mode: permissions (posix-style) for the newly-created folder |
Remove the folder named ``path``. :param str path: name of the folder to remove |
Retrieve information about a file on the remote system. The return value is an object whose attributes correspond to the attributes of Python's ``stat`` structure as returned by ``os.stat``, except that it contains fewer fields. An SFTP server may return as much or as little info as it wants, so the results may vary from server to server. Unlike a Python `python:stat` object, the result may not be accessed as a tuple. This is mostly due to the author's slack factor. The fields supported are: ``st_mode``, ``st_size``, ``st_uid``, ``st_gid``, ``st_atime``, and ``st_mtime``. :param str path: the filename to stat :return: an `.SFTPAttributes` object containing attributes about the given file |
Retrieve information about a file on the remote system, without following symbolic links (shortcuts). This otherwise behaves exactly the same as `stat`. :param str path: the filename to stat :return: an `.SFTPAttributes` object containing attributes about the given file |
Create a symbolic link (shortcut) of the ``source`` path at ``destination``. :param str source: path of the original file :param str dest: path of the newly created symlink |
Change the mode (permissions) of a file. The permissions are unix-style and identical to those used by Python's `os.chmod` function. :param str path: path of the file to change the permissions of :param int mode: new permissions |
Change the owner (``uid``) and group (``gid``) of a file. As with Python's `os.chown` function, you must pass both arguments, so if you only want to change one, use `stat` first to retrieve the current owner and group. :param str path: path of the file to change the owner and group of :param int uid: new owner's uid :param int gid: new group id |
Set the access and modified times of the file specified by ``path``. If ``times`` is ``None``, then the file's access and modified times are set to the current time. Otherwise, ``times`` must be a 2-tuple of numbers, of the form ``(atime, mtime)``, which is used to set the access and modified times, respectively. This bizarre API is mimicked from Python for the sake of consistency -- I apologize. :param str path: path of the file to modify :param tuple times: ``None`` or a tuple of (access time, modified time) in standard internet epoch time (seconds since 01 January 1970 GMT) |
Change the size of the file specified by ``path``. This usually extends or shrinks the size of the file, just like the `~file.truncate` method on Python file objects. :param str path: path of the file to modify :param size: the new size of the file :type size: int or long |
Return the target of a symbolic link (shortcut). You can use `symlink` to create these. The result may be either an absolute or relative pathname. :param str path: path of the symbolic link file :return: target path, as a `str` |
Return the normalized path (on the server) of a given path. This can be used to quickly resolve symbolic links or determine what the server is considering to be the "current folder" (by passing ``'.'`` as ``path``). :param str path: path to be normalized :return: normalized form of the given path (as a `str`) :raises IOError: if the path can't be resolved on the server |
Change the "current directory" of this SFTP session. Since SFTP doesn't really have the concept of a current working directory, this is emulated by Paramiko. Once you use this method to set a working directory, all operations on this `.SFTPClient` object will be relative to that path. You can pass in ``None`` to stop using a current working directory. :param str path: new current working directory :raises IOError: if the requested path doesn't exist on the server .. versionadded:: 1.4 |
Return the "current working directory" for this SFTP session, as emulated by Paramiko. If no directory has been set with `chdir`, this method will return ``None``. .. versionadded:: 1.4 |
Copy the contents of an open file object (``fl``) to the SFTP server as ``remotepath``. Any exception raised by operations will be passed through. The SFTP operations use pipelining for speed. :param file fl: opened file or file-like object to copy :param str remotepath: the destination path on the SFTP server :param int file_size: optional size parameter passed to callback. If none is specified, size defaults to 0 :param callable callback: optional callback function (form: ``func(int, int)``) that accepts the bytes transferred so far and the total bytes to be transferred (since 1.7.4) :param bool confirm: whether to do a stat() on the file afterwards to confirm the file size (since 1.7.7) :return: an `.SFTPAttributes` object containing attributes about the given file. .. versionadded:: 1.4 .. versionchanged:: 1.7.4 Began returning rich attribute objects. |
Copy a local file (``localpath``) to the SFTP server as ``remotepath``. Any exception raised by operations will be passed through. This method is primarily provided as a convenience. The SFTP operations use pipelining for speed. :param str localpath: the local file to copy :param str remotepath: the destination path on the SFTP server :param callable callback: optional callback function (form: ``func(int, int)``) that accepts the bytes transferred so far and the total bytes to be transferred :param bool confirm: whether to do a stat() on the file afterwards to confirm the file size :return: an `.SFTPAttributes` object containing attributes about the given file .. versionadded:: 1.4 .. versionchanged:: 1.7.4 ``callback`` and rich attribute return value added. .. versionchanged:: 1.7.7 ``confirm`` param added. |
Copy a remote file (``remotepath``) from the SFTP server and write to an open file or file-like object, ``fl``. Any exception raised by operations will be passed through. This method is primarily provided as a convenience. :param object remotepath: opened file or file-like object to copy to :param str fl: the destination path on the local host or open file object :param callable callback: optional callback function (form: ``func(int, int)``) that accepts the bytes transferred so far and the total bytes to be transferred :return: the `number <int>` of bytes written to the opened file object .. versionadded:: 1.4 .. versionchanged:: 1.7.4 Added the ``callable`` param. |
Copy a remote file (``remotepath``) from the SFTP server to the local host as ``localpath``. Any exception raised by operations will be passed through. This method is primarily provided as a convenience. :param str remotepath: the remote file to copy :param str localpath: the destination path on the local host :param callable callback: optional callback function (form: ``func(int, int)``) that accepts the bytes transferred so far and the total bytes to be transferred .. versionadded:: 1.4 .. versionchanged:: 1.7.4 Added the ``callback`` param |
