To run the program you should follow these steps:

1. Download source files using this command: git clone https://github.com/5aboteur/cft-task.git
2. Go to the target directory and run: java -jar <JAR> <OPTIONS>, where JAR is the .jar file and OPTIONS are

• <path> -- path to the directory with files you want to sort;
• --out-prefix=<pfx> -- string that will be added as prefix to the filename;
• --content-type=<type> -- type of content you want to sort (i for integers, s for strings);
• --sort-mode=<mode> -- sort order (a for ascending, d for descending)
• --workers=<n> -- number of worker threads (default=2).

Or you can open that project in Maven environment and build it by yourself.

The .jar file built for targets that have version of Java >= 1.8 and tested with the following version:

$ java -version
