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
....
May 16 total 9.75
May 17 total 8.42
May 18 total 4.85
May 19 total 4.97
May 20 total 2.00
May 21 total 2.93
May 22 total 3.10
May 23 total 1.99
