Paramiko download file

IOError — if newpath is a folder, or something else goes wrong. Retrieve information about a file on the remote system. 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 stat object, the result may not be accessed as a tuple. Create a symbolic link to the source path at destination. Change the size of the file specified by path. This usually extends or shrinks the size of the file, just like the truncate method on Python file objects.

Set the access and modified times of the file specified by path. 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. Server-side SFTP subsystem support. Since this is a SubsystemHandler , it can be and is meant to be set as the handler for "sftp" requests. Use Transport. This is a convenience function for trapping exceptions in server code and returning an appropriate result. This is meant to be a handy helper function for translating SFTP file requests into local file operations.

Representation of the attributes of a file or proxied file for SFTP in client or server mode. It attemps to mirror the object returned by os. Because SFTP allows flags to have other arbitrary named attributes, these are stored in a dict named attr.

Occasionally, the filename is also stored, in filename. Bases: paramiko. Instances of this class may be used as context managers in the same way that built-in Python file objects are. Ask the server for a hash of a section of this file. This can be used to verify a successful upload or download, or for various rsync-like operations. The file is hashed from offset , for length bytes. If length is 0, the remainder of the file is hashed. Thus, if both offset and length are zero, the entire file is hashed.

The hash results are all concatenated and returned as a single string. For example, check 'sha1', 0, , will return a string of length The first 20 bytes will be the SHA-1 of the first bytes of the file, and the last 20 bytes will be the SHA-1 of the next bytes. Change the mode permissions of this file. Change the owner uid and group gid of this file. Write out any data in the write buffer. This may do nothing if write buffering is not turned on. Returns the timeout in seconds as a float associated with the socket or ssh Channel used for this file.

Pre-fetch the remaining contents of this file in anticipation of future read calls. If reading the entire file, pre-fetching can dramatically improve the download speed by avoiding roundtrip latency. The prefetched data is stored in a buffer until read via the read method. Read at most size bytes from the file less if we hit the end of the file first.

If the size argument is negative or omitted, read all the remaining data in the file. Read up to len buff bytes into bytearray buff and return the number of bytes read.

Read one entire line from the file. A trailing newline character is kept in the string but may be absent when a file ends with an incomplete line. If the size argument is present and non-negative, it is a maximum byte count including the trailing newline and an incomplete line may be returned.

You would have to use another interface to retrieve the name of the latest file. For example, if you have a shell access: You can use some smart command like in: How do I get the name of the newest file via the Terminal? Or you can create web service web page on the server that returns the name of the latest file. Martin Prikryl Martin Prikryl k 46 46 gold badges silver badges bronze badges.

If one controls the server, can just have it maintain a symlink to the latest file; considerably less trouble than setting up a web page, and keeps everything over just one protocol which is pertinent if the SSH server for which we're using the SFTP subsystem is configured not to honor shell or exec requests. Unfortunately I can only run SFTP commands, trying to execute shell commands returns This service allows sftp connections only. Sign up or log in Sign up using Google. Sign up using Facebook.
