Jorge Moreno 2006-02-10 - Here is a frontend for LogParser
(from M$, http://www.microsoft.com/technet/scriptcenter/tools/logparser/default.mspx )
Very powerful text file parser, from what I reviewed and tried:

Step 1, Get the sample data:
http://www.briandunning.com/sample-data/ file: us-500.zip (which contains us-500.csv)
Make sure you convert the sample file to DOS format CR+LF (Its original format is Unix format so LF only for line termination)
You can do that by opening in excel and then overwriting to CSV format, or change the format with your favorite text editor.
Step 2, Prepare your query in a separate file
filename: query.sql, contents:
SELECT first_name,last_name,city FROM us-500.csv WHERE state = 'CA'
Dependecies in this example:
You will see some code being reused from this wiki (like RS's proc e'get) used in e: a tiny editor plugin for eTcl
JM 2006-Feb-13 cleaning up a little bit
JM 2006-Nov-4 just added stderr output to a file if there is any error message coming from LogParser
