DOS 32-bit, windows 32 and 64-bit versions are included. should be Vista/7 compatible. program compiles with mingw, borland c++, and djgpp.

And if uniq's on UNIX or you have UNIX tools installed on your computer, you probably won't want to call it uniq.exe. rename it uniq1 or something like that. (UNIX machines of course do not use a .exe extension)

This was compiled with Borland C++ 5.5.1 and djgpp and requires at least 128K memory. since it is STL, it could possibly be a memory hog on large text files, since everything is processed in RAM. The DOS version may start using virtual Memory at some point if it can find a C: drive.
