yah sure. I saw you guys when I peek into that.
But, mostly I may not have time to enter IRC, at the same time when you people are.

"Run" , at the same time or seperately?

either case, you can visit,

https://www.linux.com/community/forums/getting-started-with-linux/a-few-quick-questions

then the link from arochester

sounds great.

If there is place to discuss about what people know, with others [ kind of blog posts, discussion ,tutorials or whatever], it will be helpful .

Thanks Daniel

1. Learn How Linux is booting
2. Linux File Structure [ http://tldp.org/LDP/intro-linux/html/sect_03_01.html ]

I hope these 2 will give a head shot about Linux quickly.

Then you can/should start with "bash" scripting, since you want to become Admin .

Edit: And visit this site[ and other linux Q & A, Linux IRC channels] very often, to see how the problems are getting solved.

There is no cons in dual boot until a clear boot loader is configured to boot both the OSs.

If you have more amount of RAM, and have any purpose to use both the OS at the same time, virtual machines are good.
And Ubuntu makes your life easier. Will let you to use your internet, without any extra work, which can be used to solve any upcoming problem if any.

If you dont have more amount of RAM then Vitual box may not be a good choice, since Running 2 OSs at same time need some more main memory[RAM] . Dual boot option wins here.

And if you dont have any purpose to use both OS at same time, by dedicating some 1-1.5 min[ shutdown current OS , reboot, then get into another OS] in dual boot, will reduce the system load in a notable manner .

In Windows-7 , I have a good experience with Ubuntu as Guest OS.

I just waited the same thing to happen, since, its not happenening always.
And I got it now, and I dont find any difference in $PATH variable.

But, when trying to mention with current dir indication [ as you mentioned in some other thread too ], the search and autofill is faster than the prior.

Generally what I guess is the search time duration may get configured for too long?
I need to check that too..

@Matt: that link has some info about ambiguity thing. That is a must note :-)
