fun_sftp

FunSftp

FunSftp is a ruby gem that provides a nice and easy to use wrapper for the Net::SFTP library.

Reference: net-sftp

Installation

gem 'fun_sftp'

Usage

Let's say you need to send a file or directory to a remote host. Well, you can upload it to the remote host via the following:

Setup the connection and specify a source directory if desired:

include FunSftp
conn = SFTPClient.new(server, username, password)
# For authentication via keys
conn = SFTPClient.new(server, username, password, keys: [/path/to/key], host_key: 'ssh-rsa')
conn.source = 'projects/awesome_project' #optional

Changing directories chdir and listing all files ll can be useful when working in a console. FunSftp now allows you to change your location on the remote host. This saves you from constantly entering long absolute paths.

conn.chdir("projects")
# Changes Directory
# => "Current Path changed to => ./projects"

conn.ll
# Lists all files in current location
# => file1
#    file2
#    Directory1
#    Directory2

conn.pwd
# Returns the current working directory
# => "./projects"

If you need to start from scratch then reset to the base path:

conn.reset_path!
# => "Path Reset!"

Now, you can upload your file:

conn.upload!("my_local_file_name.txt", "some_remote_directory/give_a_name.txt")

or directory

conn.upload!("my_awesome_local_directory", "desired_remote_directory_name")

That's it! Check the remote host to see that your file posted.

You can also download a remote file to your local machine:

conn.download!("some_remote_directory/file_to_download_name.txt", "desired_local_name.txt")

or directory

conn.download!("some_remote_directory", "desired_local_directory_name")

Need to read a file on the remote host? Ah, it's no biggie...

conn.read("path/to/file_name.txt")
# => Hello World!

It is also possible to read the attributes size, access time and modified time.

conn.size("path/to/file_name.txt")
# => 1413455562
# works also for directories

conn.atime("path/to/file_name.txt")
# => 2014-10-16 12:32:42 +0200

conn.mtime("path/to/file_name.txt")
#=> 2014-10-16 12:32:42 +0200

When investigating items on the remote host, these commands can be handy:

conn.has_directory?("directory_name")
# returns true or false if the directory exists

conn.entries("directory_name")
# outputs a nice array of entries in the specified directory
# Pass true as a second argument if you would like to see '.' files
# => ["test1", "test2", "some_directory_here"]

conn.items_in("directory_name")
# Traverses the provided directory returning an array of directories and files
# => ["test1", "test1/h1.rb", "test2", "test2/h2.txt"]

conn.print_directory_items("directory_name")
# a print out of contained directories/files one line at a time
# => test1.txt
#    test2.png
#    fun_directory_1

conn.glob("directory_name", "**/*.rb")
# Traverses the directory specified using the second argument/matcher
# So, you can get things like...
# => ["some_directory_here/hello_world.rb", "sftp_is_fun.rb"]

FileUtils

FileUtilities are handy for doing some dirty work on the remote host.

So far, you can make/remove directories, remove/rename files

conn.mkdir!("new_directory_name_here")

Removing a directory is the same as above except you would swap mkdir! for rmdir!:

conn.rmdir!("directory_name_to_remove")

Files can be removed and renamed off the remote host:

conn.rm("file.txt")

conn.rename("old_file_name.txt", "new_file_name.txt")
# old_file_name.txt is now named new_file_name.txt on the remote host.

Hopefully, this is easy enough to work with and transfer files!!

Logging

By default, logging is turned on and will use the Rails logger if within a Rails projects. If not logging will defer to STDOUT. Logging is prominent when downloading or uploading. To turn off logging, you can create an initializer and modify the configuration by:

FunSftp.configure do |config|
  config.log = false
end

You can also define your own logger if you'd like.

FunSftp.configure do |config|
  config.logger = MyAwesomeLogger.new
end
