Subject: Appending to external file with vi?

I use the vi (ex?) command format:
|
||
|
|
|
||
|
|
:'x,.w file
|
||
|
|
|
||
|
|
to write a section of text to an external file (file).
|
||
|
|
But I don't know good way to append to an existing file.
|
||
|
|
The best I can think of is:
|
||
|
|
|
||
|
|
!'xtee -a file
|
||
|
|
|
||
|
|
where ! filters from the current position to 'x through tee.
|
||
|
|
Any ideas are welcomed. Thank you.

It's an ex command, like everything that starts with ':'.
|
||
|
|
|
||
|

How about:
|
||
|
|
|
||
|
|
:'x,.w >>file
|
||
|
|
|
||
|
|
Believe it or not, vi just informed me that "Write forms are 'w' and 'w>>'".
|
||
|
|
I'd swear I've never seen that message before. Typing
|
||
|
|
|
||
|
|
:w>
|
||
|
|
|
||
|
|
seems to trigger it.

I'd never thought of that. I might have come up with:
|
||
|
|
|
||
|
|
:'x,.w !cat>>file
|
||
|
|
^
|
||
|
|
where "w !" pipes (a portion of) the buffer into the indicated command.
|
||
|
|
Note the SPACE between the 'w' and the '!'. Without it, you'd be
|
||
|
|
creating a file named "cat>>file". (Creating files with shell meta-
|
||
|
|
characters in their names is always fun. Try creating a file named
|
||
|
|
"`rm -r $HOME`" sometime. :-)
