Hungrycat 0.3 Publishing File Printing tool

Hungrycat is a tool that prints the contents of a file on standard output while releasing the disk space occupied by the file. It works when you need to process a large number of files, but you don't have enough space to store the output file, and you no longer need to enter the file.

Use Example:

$ md5sum Bigfile
