Any suggestions?
wol $(cat [path_to_]filename_containing_mac_address)
While that does work, I'd still like to know why the documented methods
don't.
What do you have in your file? It should contain more than just your mac
address
Such as??? WOL creates a magic packet that contains the MAC address.
What else has to be included? Using only the MAC address from the
command line works fine.

Your options for the file are

MAC host port password
MAC host password
MAC host port
MAC host

MAC alone won't do, the parser expects one of the above
The MAC alone certainly works fine when included on the command line. Also, the items you mentioned are options that are not necessary for basic operation. For example, you'd specify host if the computer you're issuing the command from has more than one network adapter, so that the magic packet is sent on the right interface. The port is used if necessary to get past some packet filter. The password would be used with a SecureOn capable NIC. All this is described in the wol man page. If they are required when reading from a file, they should also be required when including the MAC as part of the file.

I have created a file called "netfinity". It's contents are the MAC address of my server or 00:02:55:47:E0:7B.
If I issue the command "wol 00:02:55:47:E0:7B", the server boots up. If I use wol -f netfinity or wol --file=netfinity or wol <netfinity, it does not work. Why is the MAC alone sufficient when included on the command line, but not when reading from a file? Someone else suggested wol $(cat netfinity), which does work but shouldn't be necessary according to the man page.
