SSHelper

This gem is supposed to make your life easier if you have to do a lot of repetitive tasks over SSH. If you are sick of doing the constant ssh [email protected], cd /opt/path/to/something, ./start.sh etc, then this tool is for you!

Installation

Install it as follows:

$ gem install sshelper

Usage

After installation, you will have to create a '.sshelper.json' file in your home directory:

$ touch ~/.sshelper.json # or ~/.sshelper.yml for the YAML format

Or, you can use the built in functionality to generate a template:

$ sshelper -t json
# or
$ sshelper -t yaml

Open it in your favorite editor:

$ nano ~/.sshelper.json
# or
$ nano ~/.sshelper.yml

And use the following structure to add labels (for YAML):

my_label1:
    description: View the content of the newest file on example.org and test.com
    servers:
        - host: example.org
          port: 22
          user: root
        - host: test.com
          port: 1234
          user: eddy
    commands:
        - ls -l
        - cat `ls -1rt | tail -1`
my_label2:
    description: List 1 file on example.org
    servers:
        - host: example.org
          port: 22
          user: root
    commands:
        - ls -1

Or if you prefer JSON:

{
  "my_label1": {
    "description": "View the content of the newest file on example.org and test.com",
    "servers": [
        {
          "host": "example.org",
          "port": 22,
          "user": "root"
        },
        {
          "host": "test.com",
          "port": 1234,
          "user": "eddy"
        }
      ],
    "commands": [
        "ls -l",
        "cat `ls -1rt | tail -1`"
      ]
  },
  "my_label2": {
    "description": "List 1 file on example.org"
    "servers": [
        {
          "host": "example.org",
          "port": 22,
          "user": "root"
        }
      ],
    "commands": [
        "ls -1"
      ]
  }
}

You can also define labels in both JSON and YAML config files. These files will be merged at runtime.

After you have added a configuration file with labels, servers and commands, you can do stuff like this:

$ sshelper my_label1

This will execute all commands defined under "my_label1" on all servers defined under that same block! Talking about enhancing your workflow...

To list all the labels you have defined with their description, you can do:

$ sshelper -l
