View local/unix mail (`mail` in the Terminal) in Mail.app

You might also want to check out this SuperUser post. The accepted answer provides a bash script that utilizes AppleScript to send an email with an attachment from a Terminal command line. This script may be more functionality than you need, but it's a great starting point. The code from the answer:

#!/bin/bash
echo "tell application \"Mail\"
    activate

    set MyEmail to make new outgoing message with properties {visible:true, subject:\"$2\", content:\"Some Message Here\"}
    tell MyEmail
        make new to recipient at end of to recipients with properties {address:\"$1\"}
        make new attachment with properties {file name:((\"$3\" as POSIX file) as alias)}
    end tell
end tell
" | osascript

Sorry, I only know command-line tools to do the job.

You can use pmset for that (like in pmset schedule wake "02/12/2012 12:42:00").

More explanations here and, of course, man pmset.

Setting Multiple "Power On" & Power Off" Events

Currently, it appears that pmset will NOT allow you to set more than one pair of "power on" & "power off" events when using a repeating schedule.

For example...

# pmset repeat shutdown MTWRFSU 02:00:00 wakeorpoweron MTWRFSU 06:45:00

The above command would set a repeating schedule that would shutdown the Mac nightly at 2 AM in the morning and startup daily at 6:45 AM.

But, if you want to set multiple "power on" & "power off" events, you could specify a specific date/time and with a little scripting you could setup a schedule for a month.

# pmset schedule wakeorpoweron "06/07/2007 07:00:00"
# pmset schedule shutdown "06/07/2007 22:00:00"
# pmset schedule wakeorpoweron "06/07/2007 00:00:00"
# pmset schedule shutdown "06/07/2007 01:00:00"
