Dear All
Can you please do me favor and let me know how can I copy some text in one file and paste it to another file ,when both of the files are being opened by vi text editor ?
Thank you in advance

To copy the current line use yy , copy a word yw , copy 4 words y4w like that

to paste what you've copied use p or P

Thank you very much for your reply . But I meant copy from one file and paste to the other file , that both of the files are being opened concurrently in separate vi sessions . Can you please do me favor and modify your proposed procedure to get through ?
Thank you in advance

Translated, this means that, unless you are either a masochist or a computer software historian, you should choose a modern text editor.

I can use an abacus that is ingeniously connected to a computer, but I would prefer to use something a bit more up-to-date. By the same reasoning I would prefer any editor -- any editor -- over vi. My antique program Apple Writer, which ran on the Apple II and was terribly limited by modern standards, easily outperformed vi.

There are dozens of programs more usable than vi, whose command set was originally designed to avoid an unnecessary waste of paper at a time when all computer transactions were conducted on a paper teletype terminal, at great cost and expenditure of time. (I was obliged to use vi while working on the NASA Space Shuttle in the early 1970s.)

The appearance of the first glass terminal ought to have marked the end of vi's useful life, but no ... not even close. At a time when there are fantastic free text editors that know a mouse is something other than a nuisance rodent, a small clique of technological throwbacks patiently enter the archaic commands required of vi, as though the last forty years had not taken place.

When people ask for useful vi commands, I am tempted to reply:

Newbies: the above is a joke, don't type it.

Not everyone can agree with you(atleast I can't). I don't understand why you hate vi this much; atleast the popularity of vi just does prove that it is NOT as BAD as you're saying

@lutusp:
I totally disagree with that and it doesn't have anything to do with the original question.

All text editors have a learning curve and some editors you like and some you don't, a very personal choice.

And be very careful with the rm command you put down (a joke I know, but still....).

@hadimotamedi: Can't you use the mouse to select (part of) the text and paste it into the other vi session?
If you have gvim installed as well, try to use that one, it comes with pulldown menu's and copy/paste options (not limited to one session).

Hope this helps.

will copy a line in buffer k

will paste the content of buffer k

vi has 26+1 buffers; you can acces them with a double quote followed by the letters a to z and this can be used when editing 2 or more files (e.g vi abc.txt def.txt). One buffer does not have a letter and only works on the current file.

see http://sparky.rice.edu/vi.html and search for buffers

Open both of your files:
eg:


press CTRL+W,N

then enter :n

you'll see two interchangeable windows; each window represents your file1 and file2

switch between windows using Ctrl+W, W

then copy and paste like i said before
