Unix Tip #4427- April 25, 2025
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.
