New files from parts of current buffer

:n,m w newfile.txt
On command mode in Vim you can save parts of the current buffer in another file. * The 'n' value represents the first line of the new file. * The 'm' value represents the last line of the new file. * newfile.txt is the newfile. The results are similar to this command in perl: perl -ne 'print if n..m' in.sql > out.sql

What Others Think

Nice. For those not familiar, :set number to show line numbers in VI, and :set nonumber to turn them off.

In vi here is a way to do this without line numbers. First, move to the line you want to start at and type "ma" (mnemonic "mark a"). 2nd, move to the line you want to end at, type "mb". Now type :'a,'b w newfile.txt

You can also hit Shift-V at the start position of the block you want, navigate to the end and type ':w newfile.txt' to parse that selection out as the new file. It's the same thing, just using the "visual" system to create the marks.
