Hi, Apparently, a man page for hostid.1 already exists since 2001. My questions therefore are: 1) Is the corresponding command available within cygwin? If so, in which part? 2) How can I find out whether some tools/commands are available under cygwin in a deterministic way without downloading and installing everything? E.g. the website http://cygwin.com/ doesn't appear to have a search function for this purpose. Any hints would be highly appreciated! Rgds r.
