Handling log files with Cygwin

How to handle log Files with the help of Cygwin?

The following steps are useful to guide that way,

1. Install Cygwin in your pc

Url: http://www.cygwin.com/mirrors.html

2. Download your production log file.

Ex: I am using FileZilla to download log file. If u want to install Filezilla in ur Pc then got this site and get it.

URL http://sourceforge.net/project/showfiles.php?group_id=21558

3. After getting the production.log file Paste that one to the follwingpath.

c:\cygwin\ home\SYSTEMNAME\(PASTEHERE) production.log
