bunch of if/then statements?

Somewhere you have to tell the script what the mac addresses are? in the exact format that etherwake needs. colon : separated or dash - separated? Then you could maybe just do a script with an IF statement for each menu option? there are a lot more better ways to do it, but you could just run this script real quick if its all you need...

#!/usr/bin/bash
MAC1=00-0e-12-34-ab-c1
MAC2=00-0e-12-34-ab-c2
MAC3=00-0e-12-34-ab-c3
echo "Which PC to wake??
1) PC1
2) PC2
3) PC3
4) Wake PC2, wait 40sec, then wake PC3
Q) Quit and take no action"
read input1
if [ $input1 == 1 ]; then
sudo /usr/sbin/etherwake -i eth1 -b $MAC1
exit 1
fi
if [ $input1 == 2 ]; then
sudo /usr/sbin/etherwake -i eth1 -b $MAC2
exit 1
fi
if [ $input1 == 3 ]; then
sudo /usr/sbin/etherwake -i eth1 -b $MAC3
exit 1
fi
if [ $input1 == 4 ]; then
sudo /usr/sbin/etherwake -i eth1 -b $MAC2
echo "PC2 sent, now waiting for 40sec"
sleep 40
sudo /usr/sbin/etherwake -i eth1 -b $MAC3
exit 1
fi
if [ $input1 == Q ] || [ $input1 == q ]; then
echo "later!"
exit 1
fi

#end of script

i just typed this out....something like this "could" work but gotta check it for notation and everything. ohh and your first line might be a different path to bash
like #/bin/bash or something like that?

LIBBASH(7)							  libbash Manual							LIBBASH(7)

NAME

     libbash -- A bash shared libraries package.

DESCRIPTION

     libbash  is  a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may
     want to load and use in scripts of your own.

     It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries.

     Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1).  A bash shared library that can be  loaded
     using
     ldbash(1) must answer 4 requirments:

     1.     It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).

     2.     It must contain a line that begins with '#EXPORT='.  That line will contain (after the '=') a list of functions that the library
	    exports.  I.e. all the function that will be usable after loading that library will be listed in that line.

     3.     It must contain a line that begins with '#REQUIRE='.  That line will contain (after the '=') a list of bash libraries that are
	    required for our library.  I.e. every bash library that is in use in our bash library must be listed there.

     4.     The library must be listed (For more information, see ldbashconfig(8)).

   Basic guidelines for writing library of your own:
     1.     Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions.

     2.     Try to declare all variables intended for internal use as local.

     3.     Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with:
		  __<library_name>_
	    For example, internal function myfoosort of hashstash library should be named as
		  __hashstash_myfoosort
	    This helps to avoid conflicts in global name space when using libraries that come from different vendors.

     4.     See html manual for full version of this guide.
