can anyone pls help me to understand without link what is vi and emacs. i know they are editor but what are they used for? how do you start them? any commands how you save?

From the command line type vi or vim either one will work. This will start the editor in that window. If you type vimtutor, this will start a very easy to use tutorial on vi. The same goes for emacs, type it at the command line and a new window will open for the emacs editor, complete with tutorial.

emacs is a much more than a text editor, its a big editing suite. Many people dont like it cause its so bulky. Vi is the orginal and standard UNIX text editor. Whatever editor you choose is up to you, but you prolly gonna need to know vi either way.

Vi is just an over-hyped front-end to ed, the REAL
unix editor ;)

start here...go to linux konsole and type vi or vi with filename
e.g. #vi
or
#vi test.txt
(for 1st eg we can give the file name at the time of saving)
for vi editor there are 3 modes
for writing text u have change it as insert mode. to do this just press 'i' then u can start typing

to save & quit,first change the mode .to do this press 'Esc'
then press ':' (shift+ and wq
eg. the end of file will now looklike
:wq

or u can type 'x' instead of wq

for giving file name give like:
:w filename

this is just an intro. ok.

I wrote this little emacs tutorial in a thread just a couple of days ago, but since you demanded a "link free zone" I'll copy & paste it here

Quick tutorial for emacs beginners:

C-x means Control-x
M-x means Meta-x (which, on a PC keyboard, is Alt-x)


To open a file: C-x C-f
To save a file: C-x C-s
To save as: C-x C-w
To get out of the minibuffer (for example, if you press C-x C-w and change your mind): C-g

To start marking text: C-space
To copy from mark to cursor: M-w
To cut from mark to cursor: C-w
To insert text: C-y

If you open a second file, then you have two active buffers. To switch between active buffers: C-b
A tab here gives a list of possible buffers to switch between

To kill a buffer: C-k

Want more?
M-x help (that is 'M-x' and then type 'help' <RET> )
enters the help system.

Before leaving, make sure to try
M-x tetris
Use arrows and space to control and C-k to exit

To shut down emacs: C-x C-c


Enjoy the world of emacs!
