Search-replacement, replacement of template

Two programki for batch work with textual information. The first - looking for the string "A" and change it to the string "B", but it does so in all the files specified directory. Second - looking line that starts with "A", ends with "B" and change the string to the string "B", it is also in all the files specified directory (instead of A, B, C can be any character sets).

These two programki can be used for example to quickly and more efficiently remove the banners, scripts, frames ... from the downloaded site.

RS Saving time is very palpable, actually editing a single file, and the changes are just the whole site.
