VI COPING BETWEEN FILES

VI editor is a very powerful editor. Suppose you want to copy line numbers 1-10 and 23-77 of file A and paste them on file B at the same time, what will you do ?? Here I am giving a tip to do this :-

Place the cursor on line no. 1
Press ESCAPE
Press Shift "(Shift double quotes)
Press a
Press 10yy [the number of lines you want to copy]

Now place the cursor on line no. 23
Press ESCAPE
Press Shift "(Shift double quotes)
Press b
Press 55yy [the number of lines you want to copy]

Now the first 10 lines have been copied in buffer "a" and next 55 lines have been copied in buffer "b".

Now press " : " (COLON) to get the vi prompt. Hit e "Destination file name"

Once you enter the Destination file go to the line where you want the first 10 lines in buffer "a" to be inserted.

Press ESCAPE.
Press Shift "(Shift double quotes)
Press a.
Press p.

The first 10 lines in buffer "a"
gets inserted.

Now go to the line where you want the rest 55 lines in buffer "b" to be inserted.

Press ESCAPE.
Press Shift "(Shift double quotes)
Press b.
Press p.

The rest 55 lines in buffer "b" gets inserted.
