    <p>I'm fairly rusty with my python and wanted to know if there was a better way or more efficient way of writing this script. </p> <p>The scripts purpose it to take a txt log and replace ' ' with replace with ',' to create a .csv.. Makes the logs a little easier to read.</p> <p>Any suggestions or advice would be appreciated. Thanks. </p> <pre><code>import sys import os import datetime t = datetime.datetime.now() ## time set to UTC zone ts = t.strftime("%Y_%m_%d_ %H_%M_%S") # Date format if len(sys.argv) != 2: # if CLi does not equal to 2 commands print print ("usage:progammename.py logname.ext") sys.exit(1) logSys = sys.argv[1] newLogSys = sys.argv[1] + "_" + ts +".csv" log = open(logSys,"r") nL = file(newLogSys ,"w") # Read from file log and write to nLog file for lineI in log.readlines(): rec=lineI.rstrip() if rec.startswith("#"): lineI=rec.replace(':',',').strip() nL.write(lineI + "\n") else: lineO=rec.replace(' ',',').strip() # nL.write(lineO + "\n") ## closes both open files; End script nL.close() log.close() =====Sample log======== #Date: 2008-04-18 15:41:16 #Fields: date time time-taken c-ip cs-username cs-auth-group x-exception-id sc-filter-result cs-categories cs(Referer) sc-status s-action cs-method rs(Content-Type) cs-uri-scheme cs-host cs-uri-port cs-uri-path cs-uri-query cs-uri-extension cs(User-Agent) s-ip sc-bytes cs-bytes x-virus-id 2012-02-02 16:19:01 14 xxx.xxx.xxx.xxx user domain\group dns_unresolved_hostname DENIED "Games" - 404 TCP_ERR_MISS POST - http updaterservice.wildtangent.com 80 /appupdate/appcheckin.wss - wss "Mozilla/4.0 (compatible; MSIE 8.0; Win32)" xxx.xxx.xxx.xxx 824 697 - </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
