Download

• Download the latest version of WoL.sh (0.1) or browse older versions.
• DISCLAIMER: WoL.sh is currently at pre-release stage - users should exercise caution.

Compatibility

WoL.sh should (but is not guaranteed to) work on most Mac or Linux systems. The author is using this utility on a macOS 10.15.3 system to wake up a Windows 10 PC, both on Wi-Fi.

Before Use

Like any shell script, you must first make WoL.sh executable. This can be done by running in terminal (assuming WoL.sh is located at ~/Desktop/WoL.sh):

chmod u+x ~/Desktop/WoL.sh

Syntax

WoL.sh [MAC] [IP] [Port]

• MAC: mandatory, MAC address of the target machine
• IP: recommeded, the magic packet will be sent to this IP, default: 255.255.255.255 (broadcast to all IPs)
• Port: optional, the magic packet will be sent to this port, default: 9

Examples

Example 1 (Recommended)

~/Desktop/WoL.sh 0F:1E:2D:3C:4B:5A 192.168.1.100

In this example:

• WoL.sh is located at ~/Desktop/WoL.sh.
• The target computer's MAC address is 0F:1E:2D:3C:4B:5A.
• This command will send a magic packet to 192.168.1.100 at port 9 (usual port for magic packets).

Example 2

~/Desktop/WoL.sh 0F:1E:2D:3C:4B:5A 192.168.1.100 9000

In this example:

• WoL.sh is located at ~/Desktop/WoL.sh.
• The target computer's MAC address is 0F:1E:2D:3C:4B:5A.
• This command will send a magic packet to 192.168.1.100 at port 9000. It is usually unnecessary to specify the port unless port 9 of the target is blocked (e.g. by a firewall).

Example 3

~/Desktop/WoL.sh 0F:1E:2D:3C:4B:5A

In this example:

• WoL.sh is located at ~/Desktop/WoL.sh.
• The target computer's MAC address is 0F:1E:2D:3C:4B:5A.
• This command will broadcast a magic packet to all systems at port 9.
• This command has not been tested.

Why WoL.sh

WoL.sh does not require installation. Most authors on the web recommend dedicated programs to perform Wake-on-LAN. A common example is "wakeonlan" for Macs. These programs are well-tested and probably contain more features than WoL.sh. But there are many scenarios where installing a program is inappropriate or not allowed (e.g. on a company machine) or there may be concerns over installing new software.

What is Wake-on-LAN or Wake-on-WLAN?

A computer can be configured to wake from sleep when it receieves a special network message known as a "Magic Packet". This technique is known as "Wake-on-LAN" (for a computer using a wired connection) or "Wake-on-WLAN" (for a computer using a wireless connection).
