I'm planning to push code to this very "project" very soon. As previously discussed I'm going to push this to the misc-utils directory of the util-linux-ng project. We can split that directory as a new project in future if ever deemed necessary. > I'm not 100% sure it should be written in C, especially > since I wrote it in Perl: And here's a shell version: http://www.pixelbeat.org/scripts/truncate I'm probably going to (re)write all "miscutils" in C though. > Russell, if you want to write a C version and do the usual > complete job (update coreutils.texi, NEWS, etc. and add tests), > I'd probably go for it.

Note I already got util-linux-ng using the "coreutils" suffixes, so this should be a good fit. Russell if you want to push code to me it's fine, but I was going to work on this tool anyway. thanks, Pádraig.
