Today I want to share some words with all those fellow Linux devotees…….<br>
<br>
But, first let me introduce my self …..<br>
<br>
My name is gopal ghosh and I live in new Delhi….<br>
my parent wanted me to become a <span style="mso-spacerun:yes"> </span>Railway
Ticket Checker at old Delhi railway station… but <br>
I want to become a computer wizard.. as pictures of computer systems influenced
me so much as a kid… that<br>
Some times in my dreams even I designed few cool mouse and trackball designs.<br>
<br>
and to fulfill my dreams I joined a local computer institute, but after 2 months
they throw me out as my questions irritate them <br>
in my view they are unable to satisfy my appetite to learn more…..<br>
<br>
still today I feel the same appetite which drives me to learn new things<br>
<br>
After this incident I strongly believe in self learning….. <span style="mso-spacerun:yes"> </span><br>
<br>now I am providing support for more than 1400 products from 32 principal brands
(<a href="http://www.adityagroup.com">www.adityagroup.com</a>) <br>
<br>
my reason for learning Linux is I want to provide tech support for Autodesk
smoke which runs on RHEL<br>
<br>
so to learn Linux I am here on this fedora mailing list…….<br>
<br>
I know what kind of information is mentioned in man pages to learn a command FIRST
I start with books with few switches and arguments<br>
<br>
THEN I go to man pages to test some more switches and arguments , some times I
find it easy to ride through the man pages, but <br>
sometimes I don't.<br>
<br>
Each time I learn a new thing I found myself deeply in love with Linux THANKS
to Linux god who created such a nice thing which can perform so many task in
one command…<br>
<br>
all that I mentioned here to emphasis the importance of a fair discussion with
out any altercation.<br>
<br>
sometimes what I know is accurate for me and wrong for others but that doesn't
mean I fight with them to prove I am right.<br>
i discuss the topic to update myself. <br>
I appreciate ur efforts to help people like me and I also request u not to
involve in any kind of altercation.<br>
<br>
here I am submitting my information for CP , CHMOD and command redirection<br>

</div>There is no indication that Gopal has read the 'man' pages or even<br>
understands that they exist. I would expect that my response(s) will<br>
invite Gopal's curiosity and that he will investigate this mysterious<br>
'man' command.<br>
<br>
The alternative is for someone to spend 20 minutes making precis of the<br>
relevant 'man' pages and posting them.<br>
