warning, non perl solution below!

Because youre using the expression "some DOS text" I will (possibly mistakenly) assume that you are using a *nix. In which case, you can use perl but its sort of overkill. I would use sed(1).

[alex@creamy]$ sed 's:^L:\n:g' filename > filename.out
[download]

of course, to create a ^L you actually need to do a ^V^L or your shell will assume you really mean ^L. Also, \n is native to the gnu sed, and may not work in BSD or ATT *nix's.
