How do I transfer files using SSH and SCP using Ruby calls?

Question

I have a file in the directory usr/share/ruby.rb. I want to transfer that file to IP-based remote devices using SSH and SCP using Ruby calls. Can anyone help me?

Solution 1

example:

require 'net/scp'

    host = '10.10.10.10'
    login = 'foo'
    password = 'bar'

    Net::SCP.start(host, login, :password => password) do |scp|
      puts 'SCP Started!'
      scp.download('/usr/share/ruby.rb', '.')
    end

there's also an scp.upload

Solution 2

The Net::SSH library includes Net::SCP, so you should start looking there.

From the Net::SCP docs:

  require 'net/scp'

  # upload a file to a remote server
  Net::SCP.upload!("remote.host.com", "username",
    "/local/path", "/remote/path",
    :password => "password")

  # download a file from a remote server
  Net::SCP.download!("remote.host.com", "username",
    "/remote/path", "/local/path",
    :password => password)

  # download a file to an in-memory buffer
  data = Net::SCP::download!("remote.host.com", "username", "/remote/path")

You'll need to modify the samples to fit your situation. The sample code isn't handing you fish to eat, it's showing you the appropriate things to use to catch your own fish.

Hi Tin, when I run the script it shows NoMethod error..what does that mean??.....this is my script..require net/scp

This is a great answer but how would I do it if I wanted to use a wildcard or regex to grab multiple files like file1 file2 file3. I tried /file* in the remote path but it is looking for a file named file*. When I scp i know i can add quotes like this scp "1.1.1.1:/file*" /localDirectory.

@NickD: I think scp is the wrong tool if you want wildcards or regex. scp wants a path which it can recursively retrieve or an individual file. Perhaps sftp or something with more capability would help, or use a ssh session to find the files, then scp them individually..
