but I feel there could be faster way to do this, without the bad-looking dummy file. How with some basic *ix -tool? Any simpler way to do it? I use Vim so I am happy also with Vim-based solution but simple unix-based solution also works (actually probably better in some cases, I can always spawn inside the editor).
Below a general case.

Just for the completeness of this list,
sed
can also do it:Sadly the
=
command prints the line numbers on separate line, so only a separatedsed
call can beautify the formatting.
