could anyone here give me a resource (book or web) so that i can learn Dos script as a UNIX programmer?

i'm stuck at a damn simple command, in UNIX we can do:

ls -t | tail -n 1

get the latest modified file in this directory.

But, i cannot find the corresponding command in Dos, simply becoz there is no "tail" in dos :(

thank you!

i only need one line as output. imagine a directory contains millions of files, no point to waste time on displaying the rest...

there's some tool kits provide by MS hv tail function, but i'd better make sure i don't relie on some extension applications to finish my script.

其实要是找unix emulator就不用这么费劲了，我就是想看看dos自己能不能做到这些……
