==> The easiest solutiuon is to use 'cut', niot 'vi':

	cut -c26- filename

==> One line at a time 'vi' macro:

	25|d^		# you'll have to escape the pipe with one or more ^V

==> Every line with an "ex' command:

	:%s/^.........................//		# that's 25 dots

==> Again with 'ex':

	:%s;^\(-a\) \(.*\)/\(.*)/\(.*)$;\1\4;
