Overview

========

**hungrycat** is a tool that prints contents of a file

on the standard output,

while simultaneously freeing disk space occupied by the file.

It can be useful if you need to process a large file, but:

- you don't have enough space to store the output file and

- you wouldn't need the input file afterwards.

Example

=======

.. code:: console

   $ md5sum bigfile

   d9b18676a36c919c1688cba61a2cf0f1  bigfile

   $ ls -lh bigfile

   -rw-r--r-- 1 jwilk users 281M Sep 13 19:46 bigfile

   $ df -h .
