I'm looking for an equivalent of the unix look command, which searches a text file for lines beginning with a given prefix. In particular, it has an option for a binary search within a pre-sorted text file.
Does anything like this exist on Windows? I know about find, but it doesn't have the binary search option.

You can find look in util-linux which is straight from ftp.kernel.org/pub/linux/utils/util-linux. look.c is simple enough to be adapted to a mingw or msvc build environment without great hassles.

There's always Cygwin.
There's probably a native solution of course.

In this case cygwin is unavailable - but according to this page it looks like look isn't available on cygwin either.

Looks great Luther! If you repost that as an answer, I'll give you the check mark. Also, are there any automated tests for the utils? I couldn't see any in an obvious location in that archive. – None – 2011-06-30T07:22:07.807
You don't say why you need the binary search option (or for that matter, why you would use look over grep.
findstr /Bdoes what you are asking, but it uses a linear search. – None – 2011-06-30T08:07:18.020
