I'm running ubuntu on my laptop. I'm using vi to edit large files. What command do I use in vi to cut blocks of the file and output them as a separate files?
In command mode:
linenumber,linenumber w filename
I.e: 6,10 w outfile will save lines 6 to 10 to a file called outfile.
Hope this helps.
With vi running in two consoles, cut or copy from one and paste into the other.
highlight the text to cut/copy
ctrl+x to cut
ctrl+c to copy
ctrl+v to paste
You can also run vimtutor for a tutorial on using vim.
If you demand vi feeling, I strongly recommend vim instead of plain vi.
It offers a visual mode that is quite powerful and works really intuitive!
Having done so, it goes like this:
* Press v to enter visual mode or V to enter visual line mode (you'll see the difference)
* make your selection using hjkl or cursor keys
* press x to cut your selection into the the "clipboard" (register in vi terminology) or y to copy it instead (This exits visual mode)
Here you are unclear in what you want to do: Do you want to write these blocks to newly-created files, or do you want to paste them into other files?
* You paste your copied or cut block of text with p
If you want a selected region to be saved in a seperate file, do this:
* With your selected region still active type : to enter command mode
* Type w new-file-name.txt
It will look like this:
This means, your currently selected region will be written into new-file-name.txt
why do people stil use vi when ther are other easy to use editors like nano , emacs etc? i find it really difficult to use :scratch: .. is there anything special about vi ??
Vi/vim has the smallest memory footprint of editors, and it is present in just about every system.
Vim/emacs is an even older flamewar within the community than KDE/Gnome. Each side has its pros and cons.
Vim does take some getting used to, but it is super powerful. It is the only editor I have needed.
As for the original question, he's got answers enough already.
Personally, I use m instead of visual mode (mostly because some of my systems don't have vim and probably never will).
(Note, the above starts at the current line, and writes two paragraphs to the newfile the ^M stands for the <ENTER> key)
As more detailed explanation.
Tanx. Your responses have been very helpful. I like vi because it pretty easy to use. There are probably countless better editors available, but vi suits me fine.
Tanx again guys. Mucho obliged.
