In a terminal window use e.g. the command 'ac', which gives (on my OSX
10.4.11):

iMac24:~ otto$ ac
total 2207.24
iMac24:~ otto$

By typing 'man ac' in a Terminal you can get more related info, or
parameters. For example when I enter 'ac -d' you'll get the following
output:
iMac24:~ otto$ ac -d
Dec 28 total 2.84
Dec 29 total 5.49
Dec 30 total 0.60
