Piped commands in paramiko

问题 How do I run piped commands in paramiko? I'm doing this: statement = 'grep thing file | grep thing2 | tail -1' last_msg = conn.execute(statement) and I get the output of grep thing file only. 回答1: Because grep doesn't know how to handle | . Get ready for some nasty escaping: statement = """sh -c 'grep thing file | grep thing2 | tail -1'""" This creates a shell on the other side, and asks it to interpret the string grep thing file | grep thing2 | tail -1 . The single quotes are necessary since

Passing a Paramiko connection SFTPFile as input to a dask.dataframe.read_parquet

I tried to pass class paramiko.sftp_file.SFTPFile instead of file URL for pandas.read_parquet and it worked fine. But when I tried the same with Dask, it threw an error. Below is the code I tried to run and the error I get. How can I make this work? import dask.dataframe as dd import parmiko ssh=paramiko.SSHClient() sftp_client = ssh.open_sftp() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) source_file=sftp_client.open(str(parquet_file),'rb') full_df = dd.read_parquet(source_file,engine='pyarrow') print(len(full_df)) Traceback (most recent call last): File "C:\Users\rrrrr\Documents

由 不问归期 提交于 2019-12-06 19:29:38
问题 I'm using Paramiko's SFTPClient to transfer file between hosts. I want my script to print the file transfer progress similar to the output seen using scp. $ scp my_file user@host user@host password: my_file 100% 816KB 815.8KB/s 00:00 $ Any idea? Thanks in advance 回答1: Use the optional callback parameter of the put function. Something like this: def printTotals(transferred, toBeTransferred): print "Transferred: {0}\tOut of: {1}".format(transferred, toBeTransferred) sftp.put("myfile",

Pass Python variable inside command with Paramiko

With this command, I want to save an output of the smartctl command of the sda drive. Now, since I use RAID, I have multiple drives, not just sda. The following command works fine: stdin, stdout, stderr = ssh.exec_command('/bin/su root -c "smartctl -a /dev/sda > /tmp/smartctl_output1"', get_pty=True) # ORIGINAL I want to achieve that I pass local Python variable "DISK" containing sda, sdb, sdc and so on instead only static value. The following line produces error: stdin, stdout, stderr = ssh.exec_command('/bin/su root -c "smartctl -a /dev/" + DISK + " > /tmp/" + DISK', get_pty=True) edit:

Context If have a script that connects to servers and then curls the localhost for the information I need Issue My issue is that I have around 200 servers I need to grab information from, the method I use, takes about 15 minutes to finish, which isn't bad but the stuff I'm wanting to do is more advanced and if I can nail multithreading I can achieve more. Desired Outcome I just want to have a threadpool of 5-10 workers so I can grab the information I need quicker. Code from Queue import Queue from multiprocessing.pool import ThreadPool import threading, os, sys import socket from threading

How to get each dependent command execution output using Paramiko exec_command

由 末鹿安然 提交于 2019-12-06 14:42:27
问题 I'm using Paramiko in order to execute a single or a multiple commands and get its output. Since Paramiko doesn't allow executing multiple commands on the same channel session I'm concatenating each command from my command list and executing it in a single line, but the output can be a whole large output text depending on the commands so it's difficult to differentiate which output is for each command. ssh.exec_command("pwd ls- l cd / ls -l") I want to have something like: command_output = [(
