Appending to an Existing File (Unix Power Tools, 3rd Edition) 17.12. Appending to an Existing File You can use the Unix redirect and append operator (>>) with w to append all or part of the buffer's contents to an existing file. For example, if you entered: :1,10w newfile and then: $ Section 20.3 :340,$w >>newfile newfile would contain lines 1-10 and line 340 to the end of the buffer. --TOR, from Learning the vi Editor (O'Reilly, 1998) 17.11.
