New files from parts of current buffer
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

Interfaces like lo can be omitted from the beginning, there are probably better ways of doing this, i'm a noob at awk.
