The general problem is this: I have some binaries and I don't know what to do with them! I've downloaded some binaries (if it helps they are in http://www.robots.ox.ac.uk/~vgg/research/affine/detectors.html

it is the first folder of the updates, the one that says ""Harris&Hessian (also Windows)"") which I need for a project. Anyway, it says there that I need cygwin, so I install it on my Windows XP. And that's where it all stops. On the folder mentioned above there is an application for windows which I run, but does nothing. In a readme file also contained in it, it says ""./extract_features.ln -harhes -i img.png -sift -pca harhessift.basis"" , so I type this in cygwin but says ""no such file or directory"", then I try to change the path, but I can't. The concept is that we have an image and through that binary, an ASCII file with some features of the image is produced, but I can't get that to work. Anyway, sorry for my messy question, but my mind is all messed up, after all this search for this.

Thanks for your help.

I'm trying to edit a text file using AWK - I want to strip back a lot of the data in my file and save the output even if I have to do it bit by bit.
I've installed cygwin on my XP box and most of the functions are there except that I cant find a file editing tool like vi or edit? Any ideas? I haven't been able to find any other shell thus far..
