DupRem

DupRem is a simple easy-to-use cross-platform application to remove duplicate and empty lines from any text file. It is also possible to keep or ignore case sensitive. Works also from command-line interface, e.g. "java -jar duprem.jar -r input_file.txt >output_file.txt", to create output file, or "java -jar duprem.jar -r input_file.txt >>output_file.txt", to create or append to output file. DupRem is portable, does not need installation and is developed in Java, so needs the Java Virtual Machine (version 6 or higher) that, in the case, is very easy to download and install.
