This is the development version of Kanrisuru. Since this is still a pre-1.0 release, we don't recommend using this in system-critical production environments.

Kanrisuru

history

Get the history of commands run on a remote server in ruby.

Basic Usage

require 'kanrisuru'
host = Kanrisuru::Remote::Host.new(host: 'centos-host', username: 'centos', keys: ['~/.ssh/id_rsa'])

result = host.history(n: 5)
result.success?
true

result.to_a
[
  [0] "sysctl net.ipv4",
  [1] "sysctl --all",
  [2] "sysctl --all --deprecated",
  [3] "sysctl net.ipv4",
  [4] "echo $?"
]

Parameters

Field Type Description
histfile string
Location of the history file.
