eg.wakeonlan 1.3

Yet another wake-on-lan library

wakeonlan

Yet another wake-on-lan command line script.

• Why another one?
• Setup
• Usage
  • Wake up a machine given its MAC address XX:XX:XX:XX:XX:XX
  • Save wake up configuration to be used later
  • Wake up a machine given saved configuration name
  • List existing configuration names
  • Delete a configuration
  • Transferring configurations to another machine
• Set up shell autocomplete
  • Bash
  • Zsh
  • Powershell

Why another one?

I couldn't find one that worked and did what I need. Specifically I need:

• A command line utility that works on Mac, Windows and Linux
• Can use saved configurations rather than force me to remember the MAC addresses of the machines I need to wake.
• Ideally, let me manipulate (create, delete, update, list) saved configurations using the same utility.
• Ideally, be open source so I can see what it is doing and know it doesn't do anything nefarious

None of the existing tools I found satisfied these criteria (even without the last two) so I wrote my own.

Setup

Pre-requisites: Python 3.7 or above. No additional packages required.

pip3 install eg.wakeonlan

On Windows, if you get a warning like:

WARNING: The script wakeonlan.exe is installed in 
'C:\Users\[username]\AppData\Roaming\Python\Python[VER]\Scripts' which is not on PATH.

You can either add this directory to your PATH or run pip3 install from Administrator command prompt.

The reason for this message is that Python does not add per user scripts directory to PATH on Windows, only the system-wide one. See this Python bug

Usage

Wake up a machine given its MAC address XX:XX:XX:XX:XX:XX

wakeonlan XX:XX:XX:XX:XX:XX [-a BroadcastAddress] [-p Port]

If not specified BroadcastAddress is 255.255.255.255 and Port is 9

Save wake up configuration to be used later

wakeonlan --save Name XX:XX:XX:XX:XX:XX [-a BroadcastAddress] [-p Port]

Name can be anything. The configuration is saved into $HOME/.wakeonlan file in JSON format --save can be abbreviated as -s

Wake up a machine given saved configuration name

wakeonlan Name

List existing configuration names

wakeonlan --list

--list can be abbreviated as -l

Delete a configuration

wakeonlan --delete Name

--delete can be abbreviated as -d

Transferring configurations to another machine

Saved configurations are stored in $HOME/.wakeonlan file (%USERPROFILE%\.wakeonlan for Windows users). Copy this file to another machine into equivalent location to transfer all the configurations.

Set up shell autocomplete

Autocomplete is supported for bash, zsh and powershell.

Bash

Add the following to your ~/.bashrc

source `wakeonlan --autocomplete-source`

Zsh

Add the following to your ~/.zhrc (make sure it is after the call to compinit)

source `wakeonlan --autocomplete-source`

Powershell

1. If you haven't already done so, you will need to enable script execution on your machine.

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

2. Remove "mark of the web" from the auto-complete script:

Unblock-File -Path $(wakeonlan --autocomplete-source)

2. Find the location of your profile file:

echo $profile

3. If it doesn't exist, create it. Then add the following to its content:

. $(wakeonlan --autocomplete-source)
